cp/cp-gimplify.c:1240
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gscfq@t-online.de
Target Milestone: ---
Using testfile gcc/testsuite/c-c++-common/gomp/master-combined-1.c
Affects g++ versions down to r9 (gcc-11 accepts it) :
$ g++-8 -c master-combined-1.c -fopenmp-simd
$ g++-11-20201206 -c master-combined-1.c -fopenmp
$
$ g++-11-20201206 -c master-combined-1.c -fopenmp-simd
master-combined-1.c: In function 'void foo(int*)':

I can't see the ICE. Moreover, g++ rejects the code:

--- Comment #2 from G. Steinmetz <gscfq@t-online.de> ---
Hmm, trying to provide some reductions along different paths :
(iff there is no g++/gcc ICE, this PR can be closed then)
(will eventually retry with some future snapshots)
$ cat z1.C
void
foo (int *a)
{
#pragma omp parallel master default(none) private (k)
}
$ cat z2.C
void
foo (int *a)
{
int i, j, k, u = 0, v = 0, w = 0, x = 0, y = 0, z = 0;
z += a[i];
#pragma omp parallel master taskloop reduction (+:u) default(none)
firstprivate(a)
}
$ cat z3.C
void bar (int *);
void
foo (int *a)
{
int i, j, k, u = 0, v = 0, w = 0, x = 0, y = 0, z = 0;
{
z += a[i];
}
#pragma omp parallel master taskloop reduction (+:u) default(none)
firstprivate(a)
}
$ cat z4.C
void
foo (int *a)
{
int i, j, k, u = 0, v = 0, w = 0, x = 0, y = 0, z = 0;
{
for (i = 0; i < 64; i++)
for (i = 0; i < 64; ++i)
z += a[i];
}
#pragma omp parallel master taskloop reduction (+:u) default(none)
firstprivate(a)
}
Yields :
z1.C:5:1: internal compiler error: Segmentation fault, in cp_genericize_r at
cp/cp-gimplify.c:1240
z1.C:5:1: internal compiler error: tree check: expected omp_clause, have

Confirmed for the test-cases. I guess Jakub will take a look.
