Subject: Disable new sroa now that all buildbots have tested it.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=8a96348a417acedef5d62eaff5245d31d0efa3f9;p=oota-llvm.git

Disable new sroa now that all buildbots have tested it.

What we have so far:
- Some clang test failures (these were known already)

- Perf results are mixed, some big regressions
  http://llvm.org/perf/db_default/v4/nts/3844
  http://llvm.org/perf/db_default/v4/nts/3845

  bullet suffers a lot. matmul is interesting: slower scalar code, faster with -vectorize.

- Some dragonegg selfhost bots crash in SROA during selfhost now
