ak at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |FIXED CC| |ak at gcc dot gnu.org Status|ASSIGNED |RESOLVED --- Comment #27 from ak at gcc dot gnu.org --- Implemented in trunk in a mostly LLVM compatible way. There are some remaining open issues (PR116019, PR115979, PR115606, PR115607) , but none should be show stoppers. There are some differences to clang, mainly that gcc handles a few cases that clang doesn't, but clang handles more cases with -O0. The success also depends on the architecture and the languages (C is better than C++ due to PR115606)
