Subject: tree-optimization/107485 - fix non-call exception ICE with inlining
X-Git-Tag: releases/gcc-10.5.0~409
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c17873d83aaeed037fb5d039df2e6303d4b6a553;p=thirdparty%2Fgcc.git

tree-optimization/107485 - fix non-call exception ICE with inlining

Inlining performs a wrong non-call exception fixup for VEC_COND_EXPRs
which on the branch fail to properly have the condition split out in
the first place.

	PR tree-optimization/107485
	* tree-inline.c (remap_gimple_stmt): Use correct type for
	split out condition of [VEC_]COND_EXPRs.
