2017-03-16stabilize store mergingAlexandre Oliva2-16/+62
Don't let pointer randomization change the order in which we process store chains. This may cause SSA_NAMEs to be released in different order, and if they're reused later, they may cause differences in SSA partitioning, leading to differences in expand, and ultimately to different code. bootstrap-debug-lean (-fcompare-debug) on i686-linux-gnu has failed in haifa-sched.c since r245196 exposed the latent ordering problem in store merging. In this case, the IR differences (different SSA names selected for copies in out-of-SSA, resulting in some off-by-one differences in pseudos) were not significant enough to be visible in the compiler output. for gcc/ChangeLog * gimple-ssa-store-merging.c (struct imm_store_chain_info): Add linked-list forward and backlinks.
