linux-yocto/3.10: fix long perf compile times1.5_M5.rc3
perf's builtin-sched.c triggers extremly long build times on some architectures due to gcc 4.7+ var-tracking functionality. To fix this, we can cherry pick the 3.12 commit: f36f83f94 [perf sched: Move struct perf_sched definition out of cmd_sched()] With this change build times are reduced from 15 to 20 minutes for qemuarm to: real 2m19.940s user 1m35.438s sys 0m11.165s For kernel's that are not carrying this patch, the following can be added to the perf recipe to also fix the issue: +++ b/meta/recipes-kernel/perf/perf.bb @@ -68,6 +68,7 @@ EXTRA_OEMAKE = \ CC="${CC}" \ AR="${AR}" \ perfexecdir=${libexecdir} \ + EXTRA_CFLAGS="-fno-var-tracking" \ NO_GTK2=1 ${TUI_DEFINES} NO_DWARF=1 ${SCRIPTING_DEFINES} \ (From OE-Core rev: 82ad5305381c2f541ef051a8fc28243cd91776fe) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
