Bug ID: 92195
Summary: [7/8 Regression/Latent] 'libgomp.c/pr90811.c:29:1:
error: address taken, but ADDRESSABLE bit not set'
('internal compiler error: verify_gimple failed')
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: ice-checking, openmp
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: amonakov at gcc dot gnu.org, jakub at gcc dot gnu.org
Target Milestone: ---
With '--enable-checking=yes,extra,rtl', I see the test case from PR90811 in
gcc-8-branch (cherry-picked in r272163), and gcc-7-branch (cherry-picked in
r275155) run into an ICE in the host (not offload!) compiler (so this must be a
latent issue, not related to the 'gcc/config/nvptx/nvptx.c' code changes):
source-gcc/libgomp/testsuite/libgomp.c/pr90811.c: In function
'main._omp_fn.1':
source-gcc/libgomp/testsuite/libgomp.c/pr90811.c:29:1: error: address
taken, but ADDRESSABLE bit not set

There is no ICE when compiling with '-foffload=disable'.
This ICE is not seen on trunk, and gcc-9-branch (cherry-picked in r272162).
