--- Comment #2 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> --- Author: rsandifo Date: Tue Oct 1 12:55:16 2019 New Revision: 276407 URL: https://gcc.gnu.org/viewcvs?rev=276407&root=gcc&view=rev Log: Fix reload after function-abi patches (PR91948) The code was passing a pseudo rather than its allocated hard reg to ira_need_caller_save_p. Running under valgrind to reproduce the failure also showed that ALLOCNO_CROSSED_CALLS_ABIS wasn't being explicitly initialised. 2019-10-01 Richard Sandiford <richard.sandif...@arm.com> gcc/ PR rtl-optimization/91948 * ira-build.c (ira_create_allocno): Initialize ALLOCNO_CROSSED_CALLS_ABIS. * ira-color.c (allocno_reload_assign): Pass hard_regno rather than regno to ira_need_caller_save_p.
