LRA merge should not affect ARM because old reload should work for ARM. There is a very small change for arm.c because I added a new argument for final.c::alter_subreg. There is few changes in IRA too but again I don't think it affect ARM. Could you provide a preprocessed file because I can not reproduce the problem by myself. Thanks. ^ permalink raw reply [flat|nested] 6+ messages in thread
