Bug ID: 104757
Summary: [12 Regression] ICE (segfault) GIMPLE pass: walloca -
in gimple_range_global
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
Target Milestone: ---
This requires that
ENABLE_OFFLOADING
is true (affects gcc/*.cc; e.g. by s/ENABLE_OFFLOADING/true/ inside gcc/*.cc).
Plus the following environment variable has to be set
OFFLOAD_TARGET_NAMES=nvptx-none
(This value, using something else [like amdgcn-amdhsa] does not ICE.)
Afterwards, the fail is:
export OFFLOAD_TARGET_NAMES=nvptx-none
f951 -quiet -O -fopenmp testsuite/gfortran.dg/gomp/clauses-1.f90
during GIMPLE pass: walloca
