Re: Parallelize the compilation using Threads

Hi I've managed to compile gimple-match.c with -ftime-report, and "phase opt and generate" seems to be what takes most of the compilation time. This is captured by the "TV_PHASE_OPT_GEN" timevar, and all its occurrences seem to be in toplev.c and lto.c. Any ideas of which part such that this varia

GCC's ICF vs. gold's ICF

Hi, why is the ICF pass in gcc not folding member functions which depend on a template parameter but happen to generate identical code? Is it because it is not identical on the IR level in the compiler? Can I somehow dump the IR in text form? The ICF pass in the gold linker can do it on binary le

Re: __has_include__ is problematic

Why not give the wierdo __has_include__ an unspellable name? ('builtinhasinclude') and take care constructing the __has_include macro expansion to have a token with exactly that spelling? Wouldn't that break -dM rather horribly? pah! However, the following thinks __DATE__ is a defined ma
