Subject: OpenMP: Fix for ICE in tree-nested.cc.
X-Git-Tag: basepoints/gcc-16~9348
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=80c03ac8041340b29325f86ed58ea8bd40a55b99;p=thirdparty%2Fgcc.git

OpenMP: Fix for ICE in tree-nested.cc.

Use gimple_omp_target_clauses() instead of gimple_omp_taskreg_clauses()
when stmt is GIMPLE_OMP_TARGET, to avoid an as_a<> ICE.  The code
immediately following this is already conditionalized in the same way.

gcc/ChangeLog
	* tree-nested.cc (convert_tramp_reference_stmt): Use the correct
	accessor for GIMPLE_OMP_TARGET clauses.
