Hi!As mentioned in the PR, e.g. wide-int is very unhappy if the shift second operand doesn't fit into the shift mode. Generally, the backend shift patterns ensure that, but in debug insns nothing enforces that. This patch fixes that by making sure e.g. QImode shifts have always at QImode shift amount, HImode shifts have QImode or HImode shift amount etc. Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2015-03-09 Jakub Jelinek <ja...@redhat.com> PR rtl-optimization/65321 * cfgexpand.c (expand_debug_expr): Ensure shift amount isn't wider than shift mode. * var-tracking.c (use_narrower_mode): Likewise. * gcc.dg/pr65321.c: New test.
OK. jeff
