2016-01-11[PR69123] fix handling of MEMs in VTA to avoid dataflow oscillationAlexandre Oliva4-6/+112
The problem arises because we used to drop overwritten MEMs from loc lists of VALUEs, but not of other onepart variables, and it just so happens that, by doing so, block 6 in the testcase has no D#5 in its output in the first pass, because the MEM holding its (previous) value was correctly dropped from value 88:88, but gains it in the second pass because D#5 has the MEM location incoming directly in its loc list, rather than indirectly in a VALUE. This incorrect binding enables other blocks to believe they have a tentative binding for D#5 in some cycles, but others, still operating on the early conclusion, believe there isn't, and they oscillate from that. Since we check for escaping MEMs in clobbers, we won't lose anything relevant by dropping call-clobbered or overwritten MEMs in all onepart variables, and this ensures the loc intersection operation in onepart vars won't let a MEM through that wasn't present in earlier iterations. for gcc/ChangeLog PR bootstrap/69123 * var-tracking.c (drop_overlapping_mem_locs): Operate on all onepart vars.
