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

[clang-tblgen] Add -print-records and -dump-json modes. Currently, if clang-tblgen is run without a mode option, it defaults to the first mode in its 'enum Action', which happens to be -gen-clang-attr-classes. I think it makes more sense for it to behave the same way as llvm-tblgen, i.e. print a diagnostic dump if it's not given any more specific instructions. I've also added the same -dump-json that llvm-tblgen supports. This means any tblgen command line (whether llvm- or clang-) can be mechanically turned into one that processes the same input into JSON.

PR14922: when printing an attribute, use the real syntax of the attribute (GNU, C++11, MS Declspec) instead of hardcoded GNU syntax. Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute. When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and name, then passed to Attr that will use the index to print itself. Thanks to Richard Smith for the idea and review. llvm-svn: 173358

Emit TypeNodes.def with tblgen. The primary goal here is to make the type node hierarchy available to other tblgen backends, although it should also make it easier to generate more selective x-macros in the future. Because tblgen doesn't seem to allow backends to preserve the source order of defs, this is not NFC because it significantly re-orders IDs. I've fixed the one (fortunately obvious) place where we relied on the old order. Unfortunately, I wasn't able to share code with the existing AST-node x-macro generators because the x-macro schema we use for types is different in a number of ways. The main loss is that subclasses aren't ordered together, which doesn't seem important for types because the hierarchy is generally very shallow with little clustering. llvm-svn: 373407

GenClangTypeNodes,
Abstract serialization: TableGen the (de)serialization code for Types. The basic technical design here is that we have three levels of readers and writers: - At the lowest level, there's a `Basic{Reader,Writer}` that knows how to emit the basic structures of the AST. CRTP allows this to be metaprogrammed so that the client only needs to support a handful of primitive types (e.g. `uint64_t` and `IdentifierInfo*`) and more complicated "inline" structures such as `DeclarationName` can just be emitted in terms of those primitives. In Clang's binary-serialization code, these are `ASTRecord{Reader,Writer}`. For now, a large number of basic structures are still emitted explicitly by code on those classes rather than by either TableGen or CRTP metaprogramming, but I expect to move more of these over. - In the middle, there's a `Property{Reader,Writer}` which is responsible for processing the properties of a larger object. The object-level reader/writer asks the property-level reader/writer to project out a particular property, yielding a basic reader/writer which will be used to read/write the property's value, like so: ``` propertyWriter.find("count").writeUInt32(node->getCount()); ``` Clang's binary-serialization code ignores this level (it uses the basic reader/writer as the property reader/writer and has the projection methods just return `*this`) and simply relies on the roperties being read/written in a stable order. - At the highest level, there's an object reader/writer (e.g. `Type{Reader,Writer}` which emits a logical object with properties. Think of this as writing something like a JSON dictionary literal. I haven't introduced support for bitcode abbreviations yet --- it turns out that there aren't any operative abbreviations for types besides the QualType one --- but I do have some ideas of how they should work. At any rate, they'll be necessary in order to handle statements. I'm sorry for not disentangling the patches that added basic and type reader/writers; I made some effort to, but I ran out of energy after disentangling a number of other patches from the work. Negligible impact on module size, time to build a set of about 20 fairly large modules, or time to read a few declarations out of them.

[Syntax] Start to move trivial Node class definitions to TableGen. NFC This defines two node archetypes with trivial class definitions: - Alternatives: the generated abstract classes are trivial as all functionality is via LLVM RTTI - Unconstrained: this is a placeholder, I think all of these are going to be Lists but today they have no special accessors etc, so we just say "could contain anything", and migrate them one-by-one to Sequence later. Compared to Dmitri's prototype, Nodes.td looks more like a class hierarchy and less like a grammar. (E.g. variants list the Alternatives parent rather than vice versa). The main reasons for this: - the hierarchy is an important part of the API we want direct control over. - e.g. we may introduce abstract bases like "loop" that the grammar doesn't care about in order to model is-a concepts that might make refactorings more expressive. This is less natural in a grammar-like idiom. - e.g. we're likely to have to model some alternatives as variants and others as class hierarchies, the choice will probably be based on natural is-a relationships. - it reduces the cognitive load of switching from editing *.td to working with code that uses the generated classes Differential Revision: https://reviews.llvm.org/D90543

Comment parsing: resolve more named character references This reimplements r173850 with a better approach: (1) use a TableGen-generated matcher instead of doing a linear search; (2) avoid allocations for new strings by converting code points to string iterals with TableGen. llvm-svn: 173931

GenClangCommentHTMLNamedCharacterReferences,
Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp. Now we have a list of all commands. This is a good thing in itself, but it also enables us to easily implement typo correction for command names. With this change we have objects that contain information about each command, so it makes sense to resolve command name just once during lexing (currently we store command names as strings and do a linear search every time some property value is needed). Thus comment token and AST nodes were changed to contain a command ID -- index into a tables of builtin and registered commands. Unknown commands are registered during parsing and thus are also uniformly assigned an ID. Using an ID instead of a StringRef is also a nice memory optimization since ID is a small integer that fits into a common bitfield in Comment class. This change implies that to get any information about a command (even a command name) we need a CommandTraits object to resolve the command ID to CommandInfo*. Currently a fresh temporary CommandTraits object is created whenever it is needed since it does not have any state. But with this change it has state -- new commands can be registered, so a CommandTraits object was added to ASTContext. Also, in libclang CXComment has to be expanded to include a CXTranslationUnit so that all functions working on comment AST nodes can get a CommandTraits object. This breaks binary compatibility of CXComment APIs. Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't need TU parameter anymore, so it was removed. This is a source-incompatible change for this C API. llvm-svn: 163540

[OpenCL] Declare builtin functions using TableGen This patch adds a `-fdeclare-opencl-builtins` command line option to the clang frontend.

It does not cover all builtins defined by the various OpenCL specifications. As such, it is not a replacement for `-finclude-default-header` yet.

[clang,ARM] Initial ACLE intrinsics for MVE. This commit sets up the infrastructure for auto-generating <arm_mve.h> and doing clang-side code generation for the builtins it relies on, and demonstrates that it works by implementing a representative sample of the ACLE intrinsics, more or less matching the ones introduced in LLVM IR by D67158,D68699,D68700. Like NEON, that header file will provide a set of vector types like uint16x8_t and C functions with names like vaddq_u32(). Unlike NEON, the ACLE spec for <arm_mve.h> includes a polymorphism system, so that you can write plain vaddq() and disambiguate by the vector types you pass to it. Unlike the corresponding NEON code, I've arranged to make every user- facing ACLE intrinsic into a clang builtin, and implement all the code generation inside clang. So <arm_mve.h> itself contains nothing but typedefs and function declarations, with the latter all using the new `__attribute__((__clang_builtin))` system to arrange that the user- facing function names correspond to the right internal BuiltinIDs. So the new MveEmitter tablegen system specifies the full sequence of IRBuilder operations that each user-facing ACLE intrinsic should translate into. Where possible, the ACLE intrinsics map to standard IR operations such as vector-typed `add` and `fadd`; where no standard representation exists, I call down to the sample IR intrinsics introduced in an earlier commit. Doing it like this means that you get the polymorphism for free just by using __attribute__((overloadable)): the clang overload resolution decides which function declaration is the relevant one, and _then_ its BuiltinID is looked up, so by the time we're doing code generation, that's all been resolved by the standard system. It also means that you get really nice error messages if the user passes the wrong combination of types: clang will show the declarations from the header file and explain why each one doesn't match. (The obvious alternative approach would be to have wrapper functions in <arm_mve.h> which pass their arguments to the underlying builtins. But that doesn't work in the case where one of the arguments has to be a constant integer: the wrapper function can't pass the constantness through. So you'd have to do that case using a macro instead, and then use C11 `_Generic` to handle the polymorphism. Then you have to add horrible workarounds because `_Generic` requires even the untaken branches to type-check successfully, and //then// if the user gets the types wrong, the error message is totally unreadable!)

Also renamed one of the SveEmitter options to be in line with MVE. Summary: This is a first patch in a series for the SveEmitter to generate the arm_sve.h header file and builtins. I've tried my best to strip down this patch as best as I could, but there are still a few changes that are not necessarily exercised by the load intrinsics in this patch, mostly around the SVEType class which has some common logic to represent types from a type and prototype string. I thought it didn't make much sense to remove that from this patch and split it up.

Emit TypeNodes.def with tblgen. The primary goal here is to make the type node hierarchy available to other tblgen backends, although it should also make it easier to generate more selective x-macros in the future. Because tblgen doesn't seem to allow backends to preserve the source order of defs, this is not NFC because it significantly re-orders IDs. I've fixed the one (fortunately obvious) place where we relied on the old order. Unfortunately, I wasn't able to share code with the existing AST-node x-macro generators because the x-macro schema we use for types is different in a number of ways. The main loss is that subclasses aren't ordered together, which doesn't seem important for types because the hierarchy is generally very shallow with little clustering. llvm-svn: 373407

Abstract serialization: TableGen the (de)serialization code for Types. The basic technical design here is that we have three levels of readers and writers: - At the lowest level, there's a `Basic{Reader,Writer}` that knows how to emit the basic structures of the AST. CRTP allows this to be metaprogrammed so that the client only needs to support a handful of primitive types (e.g. `uint64_t` and `IdentifierInfo*`) and more complicated "inline" structures such as `DeclarationName` can just be emitted in terms of those primitives. In Clang's binary-serialization code, these are `ASTRecord{Reader,Writer}`. For now, a large number of basic structures are still emitted explicitly by code on those classes rather than by either TableGen or CRTP metaprogramming, but I expect to move more of these over. - In the middle, there's a `Property{Reader,Writer}` which is responsible for processing the properties of a larger object. The object-level reader/writer asks the property-level reader/writer to project out a particular property, yielding a basic reader/writer which will be used to read/write the property's value, like so: ``` propertyWriter.find("count").writeUInt32(node->getCount()); ``` Clang's binary-serialization code ignores this level (it uses the basic reader/writer as the property reader/writer and has the projection methods just return `*this`) and simply relies on the roperties being read/written in a stable order. - At the highest level, there's an object reader/writer (e.g. `Type{Reader,Writer}` which emits a logical object with properties. Think of this as writing something like a JSON dictionary literal. I haven't introduced support for bitcode abbreviations yet --- it turns out that there aren't any operative abbreviations for types besides the QualType one --- but I do have some ideas of how they should work. At any rate, they'll be necessary in order to handle statements. I'm sorry for not disentangling the patches that added basic and type reader/writers; I made some effort to, but I ran out of energy after disentangling a number of other patches from the work. Negligible impact on module size, time to build a set of about 20 fairly large modules, or time to read a few declarations out of them.

[Syntax] Start to move trivial Node class definitions to TableGen. NFC This defines two node archetypes with trivial class definitions: - Alternatives: the generated abstract classes are trivial as all functionality is via LLVM RTTI - Unconstrained: this is a placeholder, I think all of these are going to be Lists but today they have no special accessors etc, so we just say "could contain anything", and migrate them one-by-one to Sequence later. Compared to Dmitri's prototype, Nodes.td looks more like a class hierarchy and less like a grammar. (E.g. variants list the Alternatives parent rather than vice versa). The main reasons for this: - the hierarchy is an important part of the API we want direct control over. - e.g. we may introduce abstract bases like "loop" that the grammar doesn't care about in order to model is-a concepts that might make refactorings more expressive. This is less natural in a grammar-like idiom. - e.g. we're likely to have to model some alternatives as variants and others as class hierarchies, the choice will probably be based on natural is-a relationships. - it reduces the cognitive load of switching from editing *.td to working with code that uses the generated classes Differential Revision: https://reviews.llvm.org/D90543

[OpenCL] Declare builtin functions using TableGen This patch adds a `-fdeclare-opencl-builtins` command line option to the clang frontend. This enables clang to verify OpenCL C builtin function declarations using a fast StringMatcher lookup, instead of including the opencl-c.h file with the `-finclude-default-header` option. This avoids the large parse time penalty of the header file. This commit only adds the basic infrastructure and some of the OpenCL builtins. It does not cover all builtins defined by the various OpenCL specifications. As such, it is not a replacement for `-finclude-default-header` yet.

[Clang][SVE] Parse builtin type string for scalable vectors This patch adds 'q' to mean 'scalable vector' in the builtin type string, and for SVE will return the matching builtin type as defined in the C/C++ language extensions for SVE. This patch also adds some scaffolding to generate the arm_sve.h header file, and some builtin definitions (+CodeGen) to be able to implement some simple masked load intrinsics that use the ACLE types, such as: svint8_t test_svld1_s8(svbool_t pg, const int8_t *base) { return svld1_s8(pg, base); } Reviewers: efriedma, rjmccall, rovka, rsandifo-arm, rengolin Reviewed By: efriedma Tags: #clang Differential Revision: https://reviews.llvm.org/D75298

Reland D75470 [SVE] Auto-generate builtins and header for svld1. Reworked the patch to avoid sharing a header (SVETypeFlags.h) between include/clang/Basic and utils/TableGen/SveEmitter.cpp. Now the patch generates the enum/flags which is included in TargetBuiltins.h. Also renamed one of the SveEmitter options to be in line with MVE. Summary: This is a first patch in a series for the SveEmitter to generate the arm_sve.h header file and builtins. I've tried my best to strip down this patch as best as I could, but there are still a few changes that are not necessarily exercised by the load intrinsics in this patch, mostly around the SVEType class which has some common logic to represent types from a type and prototype string. I thought it didn't make much sense to remove that from this patch and split it up.

[clang,ARM] Initial ACLE intrinsics for MVE. This commit sets up the infrastructure for auto-generating <arm_mve.h> and doing clang-side code generation for the builtins it relies on, and demonstrates that it works by implementing a representative sample of the ACLE intrinsics, more or less matching the ones introduced in LLVM IR by D67158,D68699,D68700. Like NEON, that header file will provide a set of vector types like uint16x8_t and C functions with names like vaddq_u32(). Unlike NEON, the ACLE spec for <arm_mve.h> includes a polymorphism system, so that you can write plain vaddq() and disambiguate by the vector types you pass to it. Unlike the corresponding NEON code, I've arranged to make every user- facing ACLE intrinsic into a clang builtin, and implement all the code generation inside clang. So <arm_mve.h> itself contains nothing but typedefs and function declarations, with the latter all using the new `__attribute__((__clang_builtin))` system to arrange that the user- facing function names correspond to the right internal BuiltinIDs. So the new MveEmitter tablegen system specifies the full sequence of IRBuilder operations that each user-facing ACLE intrinsic should translate into. Where possible, the ACLE intrinsics map to standard IR operations such as vector-typed `add` and `fadd`; where no standard representation exists, I call down to the sample IR intrinsics introduced in an earlier commit. Doing it like this means that you get the polymorphism for free just by using __attribute__((overloadable)): the clang overload resolution decides which function declaration is the relevant one, and _then_ its BuiltinID is looked up, so by the time we're doing code generation, that's all been resolved by the standard system. It also means that you get really nice error messages if the user passes the wrong combination of types: clang will show the declarations from the header file and explain why each one doesn't match. (The obvious alternative approach would be to have wrapper functions in <arm_mve.h> which pass their arguments to the underlying builtins. But that doesn't work in the case where one of the arguments has to be a constant integer: the wrapper function can't pass the constantness through. So you'd have to do that case using a macro instead, and then use C11 `_Generic` to handle the polymorphism. Then you have to add horrible workarounds because `_Generic` requires even the untaken branches to type-check successfully, and //then// if the user gets the types wrong, the error message is totally unreadable!)

PR14922: when printing an attribute, use the real syntax of the attribute (GNU, C++11, MS Declspec) instead of hardcoded GNU syntax. Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute. When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and name, then passed to Attr that will use the index to print itself.

Emit TypeNodes.def with tblgen. The primary goal here is to make the type node hierarchy available to other tblgen backends, although it should also make it easier to generate more selective x-macros in the future. Because tblgen doesn't seem to allow backends to preserve the source order of defs, this is not NFC because it significantly re-orders IDs. I've fixed the one (fortunately obvious) place where we relied on the old order. Unfortunately, I wasn't able to share code with the existing AST-node x-macro generators because the x-macro schema we use for types is different in a number of ways. The main loss is that subclasses aren't ordered together, which doesn't seem important for types because the hierarchy is generally very shallow with little clustering. llvm-svn: 373407

Abstract serialization: TableGen the (de)serialization code for Types. The basic technical design here is that we have three levels of readers and writers: - At the lowest level, there's a `Basic{Reader,Writer}` that knows how to emit the basic structures of the AST. CRTP allows this to be metaprogrammed so that the client only needs to support a handful of primitive types (e.g. `uint64_t` and `IdentifierInfo*`) and more complicated "inline" structures such as `DeclarationName` can just be emitted in terms of those primitives. In Clang's binary-serialization code, these are `ASTRecord{Reader,Writer}`. For now, a large number of basic structures are still emitted explicitly by code on those classes rather than by either TableGen or CRTP metaprogramming, but I expect to move more of these over. - In the middle, there's a `Property{Reader,Writer}` which is responsible for processing the properties of a larger object. The object-level reader/writer asks the property-level reader/writer to project out a particular property, yielding a basic reader/writer which will be used to read/write the property's value, like so: ``` propertyWriter.find("count").writeUInt32(node->getCount()); ``` Clang's binary-serialization code ignores this level (it uses the basic reader/writer as the property reader/writer and has the projection methods just return `*this`) and simply relies on the roperties being read/written in a stable order. - At the highest level, there's an object reader/writer (e.g. `Type{Reader,Writer}` which emits a logical object with properties. Think of this as writing something like a JSON dictionary literal. I haven't introduced support for bitcode abbreviations yet --- it turns out that there aren't any operative abbreviations for types besides the QualType one --- but I do have some ideas of how they should work. At any rate, they'll be necessary in order to handle statements. I'm sorry for not disentangling the patches that added basic and type reader/writers; I made some effort to, but I ran out of energy after disentangling a number of other patches from the work. Negligible impact on module size, time to build a set of about 20 fairly large modules, or time to read a few declarations out of them.

[OpenCL] Declare builtin functions using TableGen This patch adds a `-fdeclare-opencl-builtins` command line option to the clang frontend. This enables clang to verify OpenCL C builtin function declarations using a fast StringMatcher lookup, instead of including the opencl-c.h file with the `-finclude-default-header` option. This avoids the large parse time penalty of the header file. This commit only adds the basic infrastructure and some of the OpenCL builtins. It does not cover all builtins defined by the various OpenCL specifications. As such, it is not a replacement for `-finclude-default-header` yet.

[Syntax] Start to move trivial Node class definitions to TableGen. NFC This defines two node archetypes with trivial class definitions: - Alternatives: the generated abstract classes are trivial as all functionality is via LLVM RTTI - Unconstrained: this is a placeholder, I think all of these are going to be Lists but today they have no special accessors etc, so we just say "could contain anything", and migrate them one-by-one to Sequence later. Compared to Dmitri's prototype, Nodes.td looks more like a class hierarchy and less like a grammar. (E.g. variants list the Alternatives parent rather than vice versa). The main reasons for this: - the hierarchy is an important part of the API we want direct control over. - e.g. we may introduce abstract bases like "loop" that the grammar doesn't care about in order to model is-a concepts that might make refactorings more expressive. This is less natural in a grammar-like idiom. - e.g. we're likely to have to model some alternatives as variants and others as class hierarchies, the choice will probably be based on natural is-a relationships. - it reduces the cognitive load of switching from editing *.td to working with code that uses the generated classes Differential Revision: https://reviews.llvm.org/D90543

[clang,ARM] Initial ACLE intrinsics for MVE. This commit sets up the infrastructure for auto-generating <arm_mve.h> and doing clang-side code generation for the builtins it relies on, and demonstrates that it works by implementing a representative sample of the ACLE intrinsics, more or less matching the ones introduced in LLVM IR by D67158,D68699,D68700. Like NEON, that header file will provide a set of vector types like uint16x8_t and C functions with names like vaddq_u32(). Unlike NEON, the ACLE spec for <arm_mve.h> includes a polymorphism system, so that you can write plain vaddq() and disambiguate by the vector types you pass to it. Unlike the corresponding NEON code, I've arranged to make every user- facing ACLE intrinsic into a clang builtin, and implement all the code generation inside clang. So <arm_mve.h> itself contains nothing but typedefs and function declarations, with the latter all using the new `__attribute__((__clang_builtin))` system to arrange that the user- facing function names correspond to the right internal BuiltinIDs. So the new MveEmitter tablegen system specifies the full sequence of IRBuilder operations that each user-facing ACLE intrinsic should translate into. Where possible, the ACLE intrinsics map to standard IR operations such as vector-typed `add` and `fadd`; where no standard representation exists, I call down to the sample IR intrinsics introduced in an earlier commit. Doing it like this means that you get the polymorphism for free just by using __attribute__((overloadable)): the clang overload resolution decides which function declaration is the relevant one, and _then_ its BuiltinID is looked up, so by the time we're doing code generation, that's all been resolved by the standard system. It also means that you get really nice error messages if the user passes the wrong combination of types: clang will show the declarations from the header file and explain why each one doesn't match. (The obvious alternative approach would be to have wrapper functions in <arm_mve.h> which pass their arguments to the underlying builtins. But that doesn't work in the case where one of the arguments has to be a constant integer: the wrapper function can't pass the constantness through. So you'd have to do that case using a macro instead, and then use C11 `_Generic` to handle the polymorphism. Then you have to add horrible workarounds because `_Generic` requires even the untaken branches to type-check successfully, and //then// if the user gets the types wrong, the error message is totally unreadable!)

[Clang][SVE] Parse builtin type string for scalable vectors This patch adds 'q' to mean 'scalable vector' in the builtin type string, and for SVE will return the matching builtin type as defined in the C/C++ language extensions for SVE. This patch also adds some scaffolding to generate the arm_sve.h header file, and some builtin definitions (+CodeGen) to be able to implement some simple masked load intrinsics that use the ACLE types, such as: svint8_t test_svld1_s8(svbool_t pg, const int8_t *base) { return svld1_s8(pg, base); } Reviewers: efriedma, rjmccall, rovka, rsandifo-arm, rengolin Reviewed By: efriedma Tags: #clang Differential Revision: https://reviews.llvm.org/D75298

Reworked the patch to avoid sharing a header (SVETypeFlags.h) between include/clang/Basic and utils/TableGen/SveEmitter.cpp. Now the patch generates the enum/flags which is included in TargetBuiltins.h. Also renamed one of the SveEmitter options to be in line with MVE. Summary: This is a first patch in a series for the SveEmitter to generate the arm_sve.h header file and builtins. I've tried my best to strip down this patch as best as I could, but there are still a few changes that are not necessarily exercised by the load intrinsics in this patch, mostly around the SVEType class which has some common logic to represent types from a type and prototype string. I thought it didn't make much sense to remove that from this patch and split it up.
