--- Comment #2 from jafb at tinet dot org 2011-04-10 11:45:55 UTC --- Ok. In the documentation it said that was equivalent to -flto in BOOT_CFLAGS, that's why I used it. Now I've checked bootstrap-lto.mk and looks like it disables lto when doing a profiled bootstrap. Is it right? I wonder what gives better performance: lto or profiled-driven optimizations...
