--- Comment #21 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:077425c890927eefacb765ab5236060de9859e82 commit r12-5337-g077425c890927eefacb765ab5236060de9859e82 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Nov 17 14:18:42 2021 +0100 lim: Reset flow sensitive info even for pointers [PR103192] Since 2014 is lim clearing SSA_NAME_RANGE_INFO for integral SSA_NAMEs if moving them from conditional contexts inside of a loop into unconditional before the loop, but as the miscompilation of gimplify.c shows, we need to treat pointers the same, even for them we need to reset whether the pointer can/can't be null or the recorded pointer alignment. This fixes -FAIL: libgomp.c/../libgomp.c-c++-common/target-in-reduction-2.c (internal compiler error) -FAIL: libgomp.c/../libgomp.c-c++-common/target-in-reduction-2.c (test for excess errors) -UNRESOLVED: libgomp.c/../libgomp.c-c++-common/target-in-reduction-2.c compilation failed to produce executable -FAIL: libgomp.c++/../libgomp.c-c++-common/target-in-reduction-2.c (internal compiler error) -FAIL: libgomp.c++/../libgomp.c-c++-common/target-in-reduction-2.c (test for excess errors) -UNRESOLVED: libgomp.c++/../libgomp.c-c++-common/target-in-reduction-2.c compilation failed to produce executable -FAIL: libgomp.c++/target-in-reduction-2.C (internal compiler error) -FAIL: libgomp.c++/target-in-reduction-2.C (test for excess errors) -UNRESOLVED: libgomp.c++/target-in-reduction-2.C compilation failed to produce executable on both x86_64 and i686. 2021-11-17 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/103192 * tree-ssa-loop-im.c (move_computations_worker): Use reset_flow_sensitive_info instead of manually clearing SSA_NAME_RANGE_INFO and do it for all SSA_NAMEs, not just ones with integral types.
