This patch enables use of 'declare mapper' for 'target update' directives,
for each of C, C++ and Fortran.
There are some implementation choices here and some
"read-between-the-lines" consequences regarding this functionality,
as follows:
* It is possible to invoke a mapper which contains clause
This patch moves 'declare mapper' lookup for OpenMP clauses from parse
time to resolution time for Fortran, and adds diagnostics for missing
named mappers. This changes clause lookup in a particular case -- where
several 'declare mapper's are defined in a context, mappers declared
earlier may now
This patch adds C_ORT_DECLARE_MAPPER and C_ORT_OMP_DECLARE_MAPPER
region types to the c_omp_region_type enum, and uses them in cp/pt.cc.
Previously the C_ORT_DECLARE_SIMD code was being abused to inhibit calling
finish_omp_clauses within mapper definitions, but this patch uses one
of the new enumer
This patch reprocesses expanded clauses after 'declare mapper'
instantiation -- checking things such as duplicated clauses, illegal
use of strided accesses, and so forth. Two functions are broken out
of the 'resolve_omp_clauses' function and reused in a new function
'resolve_omp_mapper_clauses', c
This patch moves the code for explicit 'declare mapper' directive
instantiation in the Fortran front-end to openmp.cc from trans-openmp.cc.
The transformation takes place entirely in the front end's own
representation and doesn't involve middle-end trees at all. Also, having
the code in openmp.cc i
This series (for the og13 branch) implements 'declare mapper' support for
'target update' directives, and improves diagnostic behaviour relating
to mapper expansion (mostly for Fortran) in several ways.
Tested with offloading to AMD GCN. Further comments on individual
patches. I will apply (to t
