[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.

Fix the declaration printer to properly handle prototypes in C Previously, we would take a declaration like void f(void) and print it as void f(). That's correct in C++ as far as it goes, but is incorrect in C because that converts the function from having a prototype to one which does not. This turns out to matter for some of our tests that use the pretty printer where we'd like to get rid of the K&R prototypes from the test but can't because the test is checking the pretty printed function signature, as done with the ARCMT tests.

// CHECK: int main(void) {
Use functions with prototypes when appropriate; NFC A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the seventh batch of tests being updated (there are a significant number of other tests left to be updated).

[OpenMP 5.0] Parsing/sema support for map clause with mapper modifier. This patch implements the parsing and sema support for OpenMP map clauses with potential user-defined mapper attached. User defined mapper is a new feature in OpenMP 5.0. A map clause can have an explicit or implicit associated mapper, which instructs the compiler to generate extra data mapping. An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(id: struct S s) map(s, s.d[0:s.len]) struct S ss; #pragma omp target map(mapper(id) tofrom: ss) // use the mapper with name 'id' to map ss Contributed-by: Lingda Li <lildmh@gmail.com> Differential Revision: https://reviews.llvm.org/D58074 llvm-svn: 354347

[OpenMP 5.0] Parsing/sema support for from clause with mapper modifier. This patch implements the parsing and sema support for the OpenMP 'from'-clause with potential user-defined mappers attached. User-defined mappers are a new feature in OpenMP 5.0. A 'from'-clause can have an explicit or implicit associated mapper, which instructs the compiler to generate and use customized mapping functions. An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(id: struct S s) map(s, s.d[0:s.len]) struct S ss; #pragma omp target update from(mapper(id): ss) // use the mapper with name 'id' to map ss from device Contributed-by: Lingda Li <lildmh@gmail.com> Differential Revision: https://reviews.llvm.org/D58638 llvm-svn: 354817
