More fix for PR rtl-optimization/66626
* ira.h: Include "function.h". 2015-07-16 Vladimir Makarov <vmakarov@redhat.com> PR rtl-optimization/66626 * ira.h (emit-rtl.h): Include. (non_spilled_static_chain_regno_p): New. * ira-color.c (setup_profitable_hard_regs): Clear profitable regs unless it is non spilled static chain pseudo. (assign_hard_rego): Spill memory profitable allocno unless it is non spilled static chain pseudo. (allocno_spill_priority_compare): Put non spilled static chain pseudo at the end of sorted array. (improve_allocation): Do nothing if we have static chain and non-local goto. (allocno__priority_compare_func): Put non spilled static chain pseudo at the beginning of sorted array. (move_spill_restore): Ignore non spilled static chain pseudo. * ira-costs.c (find_costs_and_classes): Don't assign class NO_REGS to non spilled static chain pseudo. * lra-assigns.c (pseudo_compare_func): Put non spilled static chain pseudo at the beginning of sorted array. (spill_for): Spill non spilled static chain pseudo last. * lra-constraints.c (lra_constraints): Remove static chain pseudo check for equivalence. 2015-07-16 Vladimir Makarov <vmakarov@redhat.com> PR rtl-optimization/66626 * gcc.target/i386/pr66626-2.c: New. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@225891 138bc75d-0d04-0410-961f-82ee72b054a4
