Note that LTO runs a bunch of optimizations during the compile phase that you wouldn't get with that. Steven had issues in the past when mixing O0 and https://reviews.llvm.org/owners/package/2/ in LTO, I don't remember the details unfortunately (and Steven is OOO). Right now we don't add the `optnone` attribute when building with O0, maybe we should as well if we go this route. https://reviews.llvm.org/D28053 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
