Steven Rostedt 72441cb1fd ftrace/x86: Add support for C version of recordmcount

This patch adds the support for the C version of recordmcount and
compile times show ~ 12% improvement.

After verifying this works, other archs can add:

 HAVE_C_MCOUNT_RECORD

in its Kconfig and it will use the C version of recordmcount
instead of the perl version.

Raw Blame History

scripts contains sources for various helper programs used throughout

the kernel for the build process.

---------------------------------------------------------------------------

kallsyms: Find all symbols in vmlinux

pnmttologo: Convert pnm files to logo files

conmakehash: Create chartable

conmakehash: Create arrays for initializing the kernel console tables

hostprogs-$(CONFIG_KALLSYMS) += kallsyms hostprogs-$(CONFIG_LOGO) += pnmtologo hostprogs-$(CONFIG_VT) += conmakehash hostprogs-$(CONFIG_IKCONFIG) += bin2c hostprogs-$(BUILD_C_RECORDMCOUNT) += recordmcount

always := $(hostprogs-y) $(hostprogs-m)

The following hostprogs-y programs are only build on demand

hostprogs-y += unifdef

subdir-$(CONFIG_MODVERSIONS) += genksyms subdir-y += mod subdir-$(CONFIG_SECURITY_SELINUX) += selinux subdir-$(CONFIG_DTC) += dtc

Let clean descend into subdirs

subdir- += basic kconfig package selinux
