Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

[OpenMP][Part 2] Use reusable OpenMP context/traits handling This patch implements an almost complete handling of OpenMP contexts/traits such that we can reuse most of the logic in Flang through the OMPContext.{h,cpp} in llvm/Frontend/OpenMP. All but construct SIMD specifiers, e.g., inbranch, and the device ISA selector are define in `llvm/lib/Frontend/OpenMP/OMPKinds.def`. From these definitions we generate the enum classes `TraitSet`, `TraitSelector`, and `TraitProperty` as well as conversion and helper functions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`. The above enum classes are used in the parser, sema, and the AST attribute. The latter is not a collection of multiple primitive variant arguments that contain encodings via numbers and strings but instead a tree that mirrors the `match` clause (see `struct OpenMPTraitInfo`). The changes to the parser make it more forgiving when wrong syntax is read and they also resulted in more specialized diagnostics. The tests are updated and the core issues are detected as before. Here and elsewhere this patch tries to be generic, thus we do not distinguish what selector set, selector, or property is parsed except if they do behave exceptionally, as for example `user={condition(EXPR)}` does. The sema logic changed in two ways: First, the OMPDeclareVariantAttr representation changed, as mentioned above, and the sema was adjusted to work with the new `OpenMPTraitInfo`. Second, the matching and scoring logic moved into `OMPContext.{h,cpp}`. It is implemented on a flat representation of the `match` clause that is not tied to clang. `OpenMPTraitInfo` provides a method to generate this flat structure (see `struct VariantMatchInfo`) by computing integer score values and boolean user conditions from the `clang::Expr` we keep for them. The OpenMP context is now an explicit object (see `struct OMPContext`). This is in anticipation of construct traits that need to be tracked. The OpenMP context, as well as the `VariantMatchInfo`, are basically made up of a set of active or respectively required traits, e.g., 'host', and an ordered container of constructs which allows duplication. Matching and scoring is kept as generic as possible to allow easy extension in the future. --- Test changes: The messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have been auto generated to match the new warnings and notes of the parser. The "subset" checks were reversed causing the wrong version to be picked. The tests have been adjusted to correct this. We do not print scores if the user did not provide one. We print spaces to make lists in the `match` clause more legible.

[OPENMP 4.0] Initial support for 'omp declare reduction' construct. Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct. User-defined reductions are defined as #pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )] These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting combined value after executing the combiner. As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

[OpenMP 5.0] Parsing/sema support for "omp declare mapper" directive. This patch implements parsing and sema for "omp declare mapper" directive. User defined mapper, i.e., declare mapper directive, is a new feature in OpenMP 5.0. It is introduced to extend existing map clauses for the purpose of simplifying the copy of complex data structures between host and device (i.e., deep copy). An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(struct S s) map(s, s.d[0:s.len]) // Memory region that d points to is also mapped using this mapper.

In Clang declare target is implemented as implicit attribute for the declaration. The syntax of the declare target directive is as follows: #pragma omp declare target declarations-definition-seq #pragma omp end declare target Based on patch from Michael Wong http://reviews.llvm.org/D15321 llvm-svn: 265530

[OPENMP 4.0] Initial support for 'omp declare reduction' construct. Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct. User-defined reductions are defined as #pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )] These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting combined value after executing the combiner. As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

[OpenMP] Parsing and sema support for target update directive Summary: This patch is to add parsing and sema support for `target update` directive. Support for the `to` and `from` clauses will be added by a different patch. This patch also adds support for other clauses that are already implemented upstream and apply to `target update`, e.g. `device` and `if`. This patch is based on the original post by Kelvin Li.

[OpenMP 5.0] Parsing/sema support for "omp declare mapper" directive. This patch implements parsing and sema for "omp declare mapper" directive. User defined mapper, i.e., declare mapper directive, is a new feature in OpenMP 5.0. It is introduced to extend existing map clauses for the purpose of simplifying the copy of complex data structures between host and device (i.e., deep copy). An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(struct S s) map(s, s.d[0:s.len]) // Memory region that d points to is also mapped using this mapper.

Remove \brief commands from doxygen comments. This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

[OPENMP 4.0] Initial support for 'omp declare reduction' construct. Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct. User-defined reductions are defined as #pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )] These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting combined value after executing the combiner. As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

The intention of this change is to make it possible to consume the expanded tokens without re-runnig the preprocessor with minimal changes to the preprocessor and minimal performance penalty when preprocessing without recording the tokens. The added hook is very low-level and reconstructing the expanded token stream requires more work in the client code, the actual algorithm to collect the tokens using this hook can be found in the follow-up change.

[OpenMP][Part 2] Use reusable OpenMP context/traits handling This patch implements an almost complete handling of OpenMP contexts/traits such that we can reuse most of the logic in Flang through the OMPContext.{h,cpp} in llvm/Frontend/OpenMP. All but construct SIMD specifiers, e.g., inbranch, and the device ISA selector are define in `llvm/lib/Frontend/OpenMP/OMPKinds.def`. From these definitions we generate the enum classes `TraitSet`, `TraitSelector`, and `TraitProperty` as well as conversion and helper functions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`. The above enum classes are used in the parser, sema, and the AST attribute. The latter is not a collection of multiple primitive variant arguments that contain encodings via numbers and strings but instead a tree that mirrors the `match` clause (see `struct OpenMPTraitInfo`). The changes to the parser make it more forgiving when wrong syntax is read and they also resulted in more specialized diagnostics. The tests are updated and the core issues are detected as before. Here and elsewhere this patch tries to be generic, thus we do not distinguish what selector set, selector, or property is parsed except if they do behave exceptionally, as for example `user={condition(EXPR)}` does. The sema logic changed in two ways: First, the OMPDeclareVariantAttr representation changed, as mentioned above, and the sema was adjusted to work with the new `OpenMPTraitInfo`. Second, the matching and scoring logic moved into `OMPContext.{h,cpp}`. It is implemented on a flat representation of the `match` clause that is not tied to clang. `OpenMPTraitInfo` provides a method to generate this flat structure (see `struct VariantMatchInfo`) by computing integer score values and boolean user conditions from the `clang::Expr` we keep for them. The OpenMP context is now an explicit object (see `struct OMPContext`). This is in anticipation of construct traits that need to be tracked. The OpenMP context, as well as the `VariantMatchInfo`, are basically made up of a set of active or respectively required traits, e.g., 'host', and an ordered container of constructs which allows duplication. Matching and scoring is kept as generic as possible to allow easy extension in the future. --- Test changes: The messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have been auto generated to match the new warnings and notes of the parser. The "subset" checks were reversed causing the wrong version to be picked. The tests have been adjusted to correct this. We do not print scores if the user did not provide one. We print spaces to make lists in the `match` clause more legible.

[OpenMP][Part 2] Use reusable OpenMP context/traits handling This patch implements an almost complete handling of OpenMP contexts/traits such that we can reuse most of the logic in Flang through the OMPContext.{h,cpp} in llvm/Frontend/OpenMP. All but construct SIMD specifiers, e.g., inbranch, and the device ISA selector are define in `llvm/lib/Frontend/OpenMP/OMPKinds.def`. From these definitions we generate the enum classes `TraitSet`, `TraitSelector`, and `TraitProperty` as well as conversion and helper functions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`. The above enum classes are used in the parser, sema, and the AST attribute. The latter is not a collection of multiple primitive variant arguments that contain encodings via numbers and strings but instead a tree that mirrors the `match` clause (see `struct OpenMPTraitInfo`). The changes to the parser make it more forgiving when wrong syntax is read and they also resulted in more specialized diagnostics. The tests are updated and the core issues are detected as before. Here and elsewhere this patch tries to be generic, thus we do not distinguish what selector set, selector, or property is parsed except if they do behave exceptionally, as for example `user={condition(EXPR)}` does. The sema logic changed in two ways: First, the OMPDeclareVariantAttr representation changed, as mentioned above, and the sema was adjusted to work with the new `OpenMPTraitInfo`. Second, the matching and scoring logic moved into `OMPContext.{h,cpp}`. It is implemented on a flat representation of the `match` clause that is not tied to clang. `OpenMPTraitInfo` provides a method to generate this flat structure (see `struct VariantMatchInfo`) by computing integer score values and boolean user conditions from the `clang::Expr` we keep for them. The OpenMP context is now an explicit object (see `struct OMPContext`). This is in anticipation of construct traits that need to be tracked. The OpenMP context, as well as the `VariantMatchInfo`, are basically made up of a set of active or respectively required traits, e.g., 'host', and an ordered container of constructs which allows duplication. Matching and scoring is kept as generic as possible to allow easy extension in the future. --- Test changes: The messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have been auto generated to match the new warnings and notes of the parser. The "subset" checks were reversed causing the wrong version to be picked. The tests have been adjusted to correct this. We do not print scores if the user did not provide one. We print spaces to make lists in the `match` clause more legible.

[OpenMP][Part 2] Use reusable OpenMP context/traits handling This patch implements an almost complete handling of OpenMP contexts/traits such that we can reuse most of the logic in Flang through the OMPContext.{h,cpp} in llvm/Frontend/OpenMP. All but construct SIMD specifiers, e.g., inbranch, and the device ISA selector are define in `llvm/lib/Frontend/OpenMP/OMPKinds.def`. From these definitions we generate the enum classes `TraitSet`, `TraitSelector`, and `TraitProperty` as well as conversion and helper functions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`. The above enum classes are used in the parser, sema, and the AST attribute. The latter is not a collection of multiple primitive variant arguments that contain encodings via numbers and strings but instead a tree that mirrors the `match` clause (see `struct OpenMPTraitInfo`). The changes to the parser make it more forgiving when wrong syntax is read and they also resulted in more specialized diagnostics. The tests are updated and the core issues are detected as before. Here and elsewhere this patch tries to be generic, thus we do not distinguish what selector set, selector, or property is parsed except if they do behave exceptionally, as for example `user={condition(EXPR)}` does. The sema logic changed in two ways: First, the OMPDeclareVariantAttr representation changed, as mentioned above, and the sema was adjusted to work with the new `OpenMPTraitInfo`. Second, the matching and scoring logic moved into `OMPContext.{h,cpp}`. It is implemented on a flat representation of the `match` clause that is not tied to clang. `OpenMPTraitInfo` provides a method to generate this flat structure (see `struct VariantMatchInfo`) by computing integer score values and boolean user conditions from the `clang::Expr` we keep for them. The OpenMP context is now an explicit object (see `struct OMPContext`). This is in anticipation of construct traits that need to be tracked. The OpenMP context, as well as the `VariantMatchInfo`, are basically made up of a set of active or respectively required traits, e.g., 'host', and an ordered container of constructs which allows duplication. Matching and scoring is kept as generic as possible to allow easy extension in the future. --- Test changes: The messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have been auto generated to match the new warnings and notes of the parser. The "subset" checks were reversed causing the wrong version to be picked. The tests have been adjusted to correct this. We do not print scores if the user did not provide one.

[OpenMP][Part 2] Use reusable OpenMP context/traits handling This patch implements an almost complete handling of OpenMP contexts/traits such that we can reuse most of the logic in Flang through the OMPContext.{h,cpp} in llvm/Frontend/OpenMP. All but construct SIMD specifiers, e.g., inbranch, and the device ISA selector are define in `llvm/lib/Frontend/OpenMP/OMPKinds.def`. From these definitions we generate the enum classes `TraitSet`, `TraitSelector`, and `TraitProperty` as well as conversion and helper functions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`. The above enum classes are used in the parser, sema, and the AST attribute. The latter is not a collection of multiple primitive variant arguments that contain encodings via numbers and strings but instead a tree that mirrors the `match` clause (see `struct OpenMPTraitInfo`). The changes to the parser make it more forgiving when wrong syntax is read and they also resulted in more specialized diagnostics. The tests are updated and the core issues are detected as before. Here and elsewhere this patch tries to be generic, thus we do not distinguish what selector set, selector, or property is parsed except if they do behave exceptionally, as for example `user={condition(EXPR)}` does. The sema logic changed in two ways: First, the OMPDeclareVariantAttr representation changed, as mentioned above, and the sema was adjusted to work with the new `OpenMPTraitInfo`. Second, the matching and scoring logic moved into `OMPContext.{h,cpp}`. It is implemented on a flat representation of the `match` clause that is not tied to clang. `OpenMPTraitInfo` provides a method to generate this flat structure (see `struct VariantMatchInfo`) by computing integer score values and boolean user conditions from the `clang::Expr` we keep for them. The OpenMP context is now an explicit object (see `struct OMPContext`). This is in anticipation of construct traits that need to be tracked. The OpenMP context, as well as the `VariantMatchInfo`, are basically made up of a set of active or respectively required traits, e.g., 'host', and an ordered container of constructs which allows duplication. Matching and scoring is kept as generic as possible to allow easy extension in the future. --- Test changes: The messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have been auto generated to match the new warnings and notes of the parser. The "subset" checks were reversed causing the wrong version to be picked. The tests have been adjusted to correct this. We do not print scores if the user did not provide one. We print spaces to make lists in the `match` clause more legible.

Remove \brief commands from doxygen comments. This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

[OPENMP 4.0] Initial support for 'omp declare reduction' construct. Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct. User-defined reductions are defined as #pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )] These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting combined value after executing the combiner. As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

[OpenMP 5.0] Parsing/sema support for "omp declare mapper" directive. This patch implements parsing and sema for "omp declare mapper" directive. User defined mapper, i.e., declare mapper directive, is a new feature in OpenMP 5.0. It is introduced to extend existing map clauses for the purpose of simplifying the copy of complex data structures between host and device (i.e., deep copy). An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(struct S s) map(s, s.d[0:s.len]) // Memory region that d points to is also mapped using this mapper.

If the default memory ordering is specified as seq_cst, all atomic constructs on which memory-order-clause is not specified behave as if the seq_cst clause appears. If the default memory ordering is specified as relaxed, all atomic constructs on which memory-order-clause is not specified behave as if the relaxed clause appears. If the default memory ordering is specified as acq_rel, atomic constructs on which memory-order-clause is not specified behave as if the release clause appears if the atomic write or atomic update operation is specified, as if the acquire clause appears if the atomic read operation is specified, and as if the acq_rel clause appears if the atomic captured update operation is specified.

[OPENMP 4.0] Initial support for 'omp declare reduction' construct. Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct. User-defined reductions are defined as #pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )] These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting combined value after executing the combiner. As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

[OpenMP 5.0] Parsing/sema support for "omp declare mapper" directive. This patch implements parsing and sema for "omp declare mapper" directive. User defined mapper, i.e., declare mapper directive, is a new feature in OpenMP 5.0. It is introduced to extend existing map clauses for the purpose of simplifying the copy of complex data structures between host and device (i.e., deep copy). An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(struct S s) map(s, s.d[0:s.len]) // Memory region that d points to is also mapped using this mapper.

Resubmission of http://reviews.llvm.org/D21564 after fixes. [OpenMP] Initial implementation of parse and sema for composite pragma 'distribute parallel for' This patch is an initial implementation for #distribute parallel for. The main differences that affect other pragmas are: The implementation of 'distribute parallel for' requires blocking of the associated loop, where blocks are "distributed" to different teams and iterations within each block are scheduled to parallel threads within each team. To implement blocking, sema creates two additional worksharing directive fields that are used to pass the team assigned block lower and upper bounds through the outlined function resulting from 'parallel'. In this way, scheduling for 'for' to threads can use those bounds. As a consequence of blocking, the stride of 'distribute' is not 1 but it is equal to the blocking size. This is returned by the runtime and sema prepares a DistIncrExpr variable to hold that value. As a consequence of blocking, the global upper bound (EnsureUpperBound) expression of the 'for' is not the original loop upper bound (e.g. in for(i = 0 ; i < N; i++) this is 'N') but it is the team-assigned block upper bound. Sema creates a new expression holding the calculation of the actual upper bound for 'for' as UB = min(UB, PrevUB), where UB is the loop upper bound, and PrevUB is the team-assigned block upper bound. llvm-svn: 273884

PR40642: Fix determination of whether the final statement of a statement expression is a discarded-value expression. Summary: We used to get this wrong in three ways: 1) During parsing, an expression-statement followed by the }) ending a statement expression was always treated as producing the value of the statement expression. That's wrong for ({ if (1) expr; }) 2) During template instantiation, various kinds of statement (most statements not appearing directly in a compound-statement) were not treated as discarded-value expressions, resulting in missing volatile loads (etc). 3) In all contexts, an expression-statement with attributes was not treated as producing the value of the statement expression, eg ({ [[attr]] expr; }).

[OpenMP 5.0] Parsing/sema support for "omp declare mapper" directive. This patch implements parsing and sema for "omp declare mapper" directive. User defined mapper, i.e., declare mapper directive, is a new feature in OpenMP 5.0. It is introduced to extend existing map clauses for the purpose of simplifying the copy of complex data structures between host and device (i.e., deep copy). An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(struct S s) map(s, s.d[0:s.len]) // Memory region that d points to is also mapped using this mapper.

Resubmission of http://reviews.llvm.org/D21564 after fixes. [OpenMP] Initial implementation of parse and sema for composite pragma 'distribute parallel for' This patch is an initial implementation for #distribute parallel for. The main differences that affect other pragmas are: The implementation of 'distribute parallel for' requires blocking of the associated loop, where blocks are "distributed" to different teams and iterations within each block are scheduled to parallel threads within each team. To implement blocking, sema creates two additional worksharing directive fields that are used to pass the team assigned block lower and upper bounds through the outlined function resulting from 'parallel'. In this way, scheduling for 'for' to threads can use those bounds. As a consequence of blocking, the stride of 'distribute' is not 1 but it is equal to the blocking size. This is returned by the runtime and sema prepares a DistIncrExpr variable to hold that value. As a consequence of blocking, the global upper bound (EnsureUpperBound) expression of the 'for' is not the original loop upper bound (e.g. in for(i = 0 ; i < N; i++) this is 'N') but it is the team-assigned block upper bound. Sema creates a new expression holding the calculation of the actual upper bound for 'for' as UB = min(UB, PrevUB), where UB is the loop upper bound, and PrevUB is the team-assigned block upper bound. llvm-svn: 273884

PR40642: Fix determination of whether the final statement of a statement expression is a discarded-value expression. Summary: We used to get this wrong in three ways: 1) During parsing, an expression-statement followed by the }) ending a statement expression was always treated as producing the value of the statement expression. That's wrong for ({ if (1) expr; }) 2) During template instantiation, various kinds of statement (most statements not appearing directly in a compound-statement) were not treated as discarded-value expressions, resulting in missing volatile loads (etc). 3) In all contexts, an expression-statement with attributes was not treated as producing the value of the statement expression, eg ({ [[attr]] expr; }). Also fix incorrect enforcement of OpenMP rule that directives can "only be placed in the program at a position where ignoring or deleting the directive would result in a program with correct syntax". In particular, a label (be it goto, case, or default) should not affect whether directives are permitted.

[OPENMP 4.0] Initial support for '#pragma omp declare simd' directive. Initial parsing/sema/serialization/deserialization support for '#pragma omp declare simd' directive. The 'declare simd' construct can be applied to a function to enable the creation of one or more versions that can process multiple arguments using SIMD instructions from a single invocation from a SIMD loop. If the function has any declarations, then the declare simd construct for any declaration that has one must be equivalent to the one specified for the definition. Otherwise, the result is unspecified. This pragma can be applied many times to the same declaration. Internally this pragma is represented as an attribute. But we need special processing for this pragma because it must be used before function declaration, this directive is applied to.

[OPENMP] Parsing and Sema support for 'omp declare target' directive Add parsing, sema analysis for 'declare target' construct for OpenMP 4.0 (4.5 support will be added in separate patch). The declare target directive specifies that variables, functions (C, C++ and Fortran), and subroutines (Fortran) are mapped to a device. The declare target directive is a declarative directive. In Clang declare target is implemented as implicit attribute for the declaration. The syntax of the declare target directive is as follows: #pragma omp declare target declarations-definition-seq #pragma omp end declare target Based on patch from Michael Wong http://reviews.llvm.org/D15321 llvm-svn: 265530

[OpenMP] Fix handling of clause on wrong directive, by Joel. E. Denny Summary: First, this patch fixes an assert failure when, for example, "omp for" has num_teams. Second, this patch prevents duplicate diagnostics when, for example, "omp for" has uniform. This patch makes the general assumption (even where it doesn't necessarily fix an existing bug) that it is worthless to perform sema for a clause that appears on a directive on which OpenMP does not permit that clause. However, due to this assumption, this patch suppresses some diagnostics that were expected in the test suite. I assert that those diagnostics were likely just distracting to the user.

However, due to this assumption, this patch suppresses some diagnostics that were expected in the test suite. I assert that those diagnostics were likely just distracting to the user.

Format of 'if' clause is as follows: ``` if([ directive-name-modifier :] scalar-logical-expression) ``` The restriction rules are also changed. 1. If any 'if' clause on the directive includes a 'directive-name-modifier' then all 'if' clauses on the directive must include a 'directive-name-modifier'. 2. At most one 'if' clause without a 'directive-name-modifier' can appear on the directive. 3. At most one 'if' clause with some particular 'directive-name-modifier' can appear on the directive. 'directive-name-modifier' is important for combined directives and allows to separate conditions in 'if' clause for simple sub-directives in combined directive. This 'directive-name-modifier' identifies the sub-directive to which this 'if' clause must be applied. llvm-svn: 246747

[OpenMP] Fix handling of clause on wrong directive, by Joel. E. Denny Summary: First, this patch fixes an assert failure when, for example, "omp for" has num_teams. Second, this patch prevents duplicate diagnostics when, for example, "omp for" has uniform. This patch makes the general assumption (even where it doesn't necessarily fix an existing bug) that it is worthless to perform sema for a clause that appears on a directive on which OpenMP does not permit that clause. However, due to this assumption, this patch suppresses some diagnostics that were expected in the test suite. I assert that those diagnostics were likely just distracting to the user.

[OpenMP] Fix handling of clause on wrong directive, by Joel. E. Denny Summary: First, this patch fixes an assert failure when, for example, "omp for" has num_teams. Second, this patch prevents duplicate diagnostics when, for example, "omp for" has uniform. This patch makes the general assumption (even where it doesn't necessarily fix an existing bug) that it is worthless to perform sema for a clause that appears on a directive on which OpenMP does not permit that clause. However, due to this assumption, this patch suppresses some diagnostics that were expected in the test suite. I assert that those diagnostics were likely just distracting to the user.

Rather than sprinkle calls to DiagnoseUnusedExprResult() around in places where we want diagnostics, we now diagnose unused expression statements and full expressions in a more generic way when acting on the final expression statement.

[OpenMP] Fix handling of clause on wrong directive, by Joel. E. Denny Summary: First, this patch fixes an assert failure when, for example, "omp for" has num_teams. Second, this patch prevents duplicate diagnostics when, for example, "omp for" has uniform. This patch makes the general assumption (even where it doesn't necessarily fix an existing bug) that it is worthless to perform sema for a clause that appears on a directive on which OpenMP does not permit that clause. However, due to this assumption, this patch suppresses some diagnostics that were expected in the test suite. I assert that those diagnostics were likely just distracting to the user.

Format of 'if' clause is as follows: ``` if([ directive-name-modifier :] scalar-logical-expression) ``` The restriction rules are also changed. 1. If any 'if' clause on the directive includes a 'directive-name-modifier' then all 'if' clauses on the directive must include a 'directive-name-modifier'. 2. At most one 'if' clause without a 'directive-name-modifier' can appear on the directive. 3. At most one 'if' clause with some particular 'directive-name-modifier' can appear on the directive. 'directive-name-modifier' is important for combined directives and allows to separate conditions in 'if' clause for simple sub-directives in combined directive. This 'directive-name-modifier' identifies the sub-directive to which this 'if' clause must be applied. llvm-svn: 246747

Refactor the way we handle diagnosing unused expression results. Rather than sprinkle calls to DiagnoseUnusedExprResult() around in places where we want diagnostics, we now diagnose unused expression statements and full expressions in a more generic way when acting on the final expression statement. This results in more appropriate diagnostics for [[nodiscard]] where we were previously lacking them, such as when the body of a for loop is not a compound statement.
