Bug ID: 123794
Summary: [openmp] ice during GIMPLE pass: vect
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C++ code:
extern long a[];
#pragma omp declare simd
long my_fun(long);
long foo_i;
void foo() {
#pragma omp simd
for (foo_i = 0; foo_i < 3; foo_i += 1)
a[foo_i] = my_fun(foo_i);
}
compiled by recent gcc trunk, does this:
cvise $ ~/gcc/results/bin/gcc -c -w -fopenmp bug1175.cc
cvise $ ~/gcc/results/bin/gcc -c -w -fopenmp -O1 bug1175.cc
bug1175.cc: In function ‘void foo()’:
bug1175.cc:5:6: error: missing definition
5 | void foo() {
| ^~~
for SSA_NAME: .MEM_9 in statement:
# .MEM_30 = VDEF <.MEM_9>
MEM <vector(2) long int> [(long int *)vectp_a.10_28] = vect__10.9_26;
during GIMPLE pass: vect
bug1175.cc:5:6: internal compiler error: verify_ssa failed
gcc 15.2.0 doesn't like it:
cvise $ ~/gcc/results.15.2.0/bin/gcc -c -w -fopenmp -O1 bug1175.cc
bug1175.cc: In function ‘void foo()’:
bug1175.cc:5:6: error: missing definition
5 | void foo() {
| ^~~
for SSA_NAME: .MEM_9 in statement:
# .MEM_30 = VDEF <.MEM_9>
MEM <vector(2) long int> [(long int *)vectp_a.10_28] = vect__10.9_26;
during GIMPLE pass: vect
bug1175.cc:5:6: internal compiler error: verify_ssa failed
so the error is before then.
