--- Comment #13 from Sandra Loosemore <sandra at codesourcery dot com> --- I think the new version of the patch in comment 11 is probably OK. I ran the entire gcc testsuite (but not g++, etc yet) and have a couple hundred regressions compared to my r217010 build, but I don't see a pattern of them being obviously lto-related. (I started skimming over them and they look mostly like broken test cases.)
