Bug ID: 103349
Summary: ICE in potential_constant_expression_1, at
cp/constexpr.c:9104 (sorry, unimplemented: unexpected
AST of kind omp_masked)
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, openmp
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
g++-12.0.0-alpha20211114 snapshot (g:3057f1ab737582a9fb37a3fb967ed8bf3659f2f4)
ICEs when compiling the following testcase, reduced from
test/OpenMP/masked_codegen.cpp from the clang 13.0.0 test suite, w/ -fopenmp:
int c;
void
lambda_masked (int a, int b)
{
[=] ()
{
#pragma omp masked
c = a + b;
};
}
% g++-12.0.0 -fopenmp -c zvbd9hfy.cpp
