------- Additional Comments From gschafer at zip dot com dot au 2005-01-05 00:19 ------- Here are some timimgs from my test runs. This is all done with:
--enable-languages=c --disable-checking make bootstrap gcc-4.0 14:50 gcc-4.0 12.25 -> with STAGE1_CHECKING manually removed as you can see, STAGE1_CHECKING results in a 19.5% slowdown! Here it is again, but this time adding in --disable-mudflap: gcc-4.0 14.07 gcc-4.0 12.04 -> with STAGE1_CHECKING manually removed Quicker, but still a 17% slowdown. Now for comparison purposes, here is gcc-3.4.3 gcc-3.4.3 7.25 Conclusions: - STAGE1_CHECKING most definitely slows down C only bootstraps by up to 19.5% - C only bootstrap times on GCC-4 have almost exactly doubled since 3.4.3 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19223
