Bug ID: 84556
Summary: C++17, lambda, OpenMP simd: sorry, unimplemented:
unexpected AST
Product: gcc
Version: 7.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bisqwit at iki dot fi
Target Milestone: ---
This code generates an AST error when compiled with -std=c++17 -fopenmp.
void foo()
{
auto keymaker = [](void)
{
#pragma omp simd
for(unsigned pos = 0; pos < 4; ++pos)
{
}
};
}
test.cc: In lambda function:
test.cc:9:5: sorry, unimplemented: unexpected AST of kind omp_simd
};
^
test.cc:9: confused by earlier errors, bailing out
Compiling without -fopenmp, or using an earlier standard mode such as
-std=c++14 or -std=c++11, the error is not produced.
Tested on: g++-7 (Debian 7.2.0-19) 7.2.0
