Bug ID: 64747
Summary: OpenACC: Rejects "gang()" in acc loop/kernels
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Keywords: openacc, rejects-valid
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: tschwinge at gcc dot gnu.org
Example is the code
https://github.com/parallel-forall/code-samples/tree/master/posts/002-openacc-example/step3
Compiling the C example fails as follows - the "gang(" looks okay at a glance
and it seems to compile correctly with PGI's compiler. [Additionally, the ME
support seems to be missing.]
gcc -w -fopenacc -I../common *.c -lm
