Subject: [PATCH 2/3] Correct the reported line number in c++ combined OpenACC directives
Date: Wed, 25 Jul 2018 15:29:00 -0000 [thread overview]
Message-ID: <3c6835f87a8d9b25e46106f666a1d2850c781bd4.1532531520.git.cesar@codesourcery.com> (raw)
In-Reply-To: <cover.1532531520.git.cesar@codesourcery.com>
Like the fortran FE, the C++ FE doesn't set the expr_location of the
split acc loop in combined acc parallel/kernels loop directives. This
only happens for with combined directives, otherwise
cp_parser_omp_construct would be responsible for setting the
location. After fixing this bug, I was able to resolve a couple of
long standing diagnostics discrepancies between the c/c++ FEs in the
test suite.
Is this patch OK for trunk? I bootstrapped and regtested using x86_64
with nvptx offloading.
Thanks,
Cesar

gcc/cp/
* parser.c (cp_parser_oacc_kernels_parallel): Adjust EXPR_LOCATION
on the combined acc loop.
gcc/testsuite/
* c-c++-common/goacc/combined-directives-3.c: New test.
* c-c++-common/goacc/loop-2-kernels.c (void K): Adjust test.
* c-c++-common/goacc/loop-2-parallel.c (void P): Adjust test.
* c-c++-common/goacc/loop-3.c (void p2): Adjust test.
