--- Comment #19 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Jakub Jelinek from comment #18) > Attached is an attempt to fix this just by setting JUMP_LABEL on the > indirect jump, then computed_jump_p predicate will be false and the various > places in RTL optimizers will be told where it jumps to. Not 100% how > adding the JUMP_LABEL plays with e.g. LABEL_NUSES, should it increment it or > not, or do only LABEL_REFs count for that? In any case, the patch fixes the > bug in the cross compiler, can't test it on Alpha though, perhaps could test > say on ppc64 and s390x which also don't define HAS_LONG_UNCOND_BRANCH to > non-zero. But, our testsuite coverage for -freorder-blocks-and-partition is > very limited anyway. I have started bootstrap on Alpha.
