[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.

[OpenMP 5.0] Parsing/sema support for to clause with mapper modifier. This patch implements the parsing and sema support for OpenMP to clause with potential user-defined mappers attached. User defined mapper is a new feature in OpenMP 5.0. A to/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 to(mapper(id): ss) // use the mapper with name 'id' to map ss to device Contributed-by: <lildmh@gmail.com> Differential Revision: https://reviews.llvm.org/D58523 llvm-svn: 354698
