Hi!This patch is a fix for gomp4.1 branch ICEs on FAIL libgomp.c/for-5.c FAIL libgomp.c++/for-13.C that can be reproduced with intelmic emul offloading even on the trunk with the attached testcase. The problem is that LTO streaming doesn't really like earlier unreferenced VAR_DECLs to be streamed late during output_function (from output_cfg). The patch fixes it by clearing loop->simduid when optimizations removed all IL uses of the var and remove_unused_locals is about to nuke it from cfun->local_decls. Ok for trunk/5.3 if it passes bootstrap/regtest? 2015-09-04 Jakub Jelinek <ja...@redhat.com> PR middle-end/67452 * tree-ssa-live.c: Include cfgloop.h. (remove_unused_locals): Clear loop->simduid if simduid is about to be removed from cfun->local_decls. * gcc.dg/lto/pr67452_0.c: New test.
OK. jeff
