	  Note that Buildroot does not try to invalidate the cache
	  contents when the compiler changes in an incompatible
	  way. Therefore, if you make a change to the compiler version
	  and/or configuration, you are responsible for purging the
	  ccache cache by removing the $HOME/.buildroot-ccache
	  directory.

	help
	  Do not optimize. This is the default.

config BR2_OPTIMIZE_1
	bool "optimization level 1"
	help
	  Optimize. Optimizing compilation takes somewhat more time,
	  and a lot more memory for a large function. With -O, the
	  compiler tries to reduce code size and execution time,
	  without performing any optimizations that take a great deal
	  of compilation time. -O turns on the following optimization
	  flags: -fdefer-pop -fdelayed-branch -fguess-branch-probability
	  -fcprop-registers -floop-optimize -fif-conversion
	  -fif-conversion2 -ftree-ccp -ftree-dce -ftree-dominator-opts
	  -ftree-dse -ftree-ter -ftree-lrs -ftree-sra -ftree-copyrename
	  -ftree-fre -ftree-ch -funit-at-a-time -fmerge-constants
	  -O also turns on -fomit-frame-pointer on machines where doing
	  so does not interfere with debugging.

config BR2_OPTIMIZE_2
	bool "optimization level 2"
	help
	  Optimize even more. GCC performs nearly all supported optimizations
	  that do not involve a space-speed tradeoff. The compiler does not
	  perform loop unrolling or function inlining when you specify -O2.
	  As compared to -O, this option increases both compilation time and
	  the performance of the generated code. -O2 turns on all optimization
	  flags specified by -O. It also turns on the following optimization
	  flags: -fthread-jumps -fcrossjumping -foptimize-sibling-calls
	  -fcse-follow-jumps -fcse-skip-blocks -fgcse  -fgcse-lm
	  -fexpensive-optimizations -fstrength-reduce -frerun-cse-after-loop

	  Please note the warning under -fgcse about invoking -O2 on programs
	  that use computed gotos.

config BR2_OPTIMIZE_3
	bool "optimization level 3"
	help
	  Optimize yet more. -O3 turns on all optimizations specified by -O2
	  and also turns on the -finline-functions, -funswitch-loops and
	  -fgcse-after-reload options.

config BR2_OPTIMIZE_S
	bool "optimize for size"
	help
	  Optimize for size. -Os enables all -O2 optimizations that do not
	  typically increase code size. It also performs further optimizations
	  designed to reduce code size. -Os disables the following optimization
	  flags: -falign-functions -falign-jumps -falign-loops -falign-labels

	  -ftree-vect-loop-version

	  -fstack-protector-all option.

	  See http://www.linuxfromscratch.org/hints/downloads/files/ssp.txt
	  for details.

	  Note that this requires the toolchain to have SSP

config BR2_PREFER_STATIC_LIB
	bool "prefer static libraries"
	help
	  Where possible, build and use static libraries for the target.
	  This potentially increases your code size and should only be
	  used if you know what you do.
	  The default is to build dynamic libraries and use those on

	  WARNING: This is highly experimental at the moment.

config BR2_PACKAGE_OVERRIDE_FILE

	  A package override file is a short makefile that contains
	  variable definitions of the form <pkg>_OVERRIDE_SRCDIR,

	  as the source directory for a particular package. See the
	  Buildroot documentation for more details on this feature.

config BR2_GLOBAL_PATCH_DIR
	string "global patch directories"
	help
	  You may specify a space separated list of one or more directories
	  containing global package patches. For a specific version
	  <packageversion> of a specific package <packagename>, patches are
	  applied as follows:

	  First, the default Buildroot patch set for the package is applied
	  from the package's directory in Buildroot.

	  Then for every directory - <global-patch-dir> - that exists in
	  BR2_GLOBAL_PATCH_DIR, if the directory
	  <global-patch-dir>/<packagename>/<packageversion>/ exists, then all
	  *.patch files in this directory will be applied.

	  Otherwise, if the directory <global-patch-dir>/<packagename> exists,
	  then all *.patch files in the directory will be applied.
