config BR2_DEBUG_1
	bool "debug level 1"
	help
	  Debug level 1 produces minimal information, enough
	  for making backtraces in parts of the program that
	  you don't plan to debug. This includes descriptions
	  of functions and external variables, but no information
	  about local variables and no line numbers.

config BR2_DEBUG_2
	bool "debug level 2"
	help
	  The default gcc debug level is 2

config BR2_DEBUG_3
	bool "debug level 3"
	help
	  Level 3 includes extra information, such as all the
	  macro definitions present in the program. Some debuggers
	  support macro expansion when you use -g3.

	prompt "gcc optimization level"
	default BR2_OPTIMIZE_S
	help
	  Set the optimization level for gcc

config BR2_OPTIMIZE_0
	bool "optimization level 0"
	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
	  -frerun-loop-opt -fcaller-saves -fpeephole2 -fschedule-insns
	  -fschedule-insns2 -fsched-interblock -fsched-spec -fregmove
	  -fstrict-aliasing -fdelete-null-pointer-checks -freorder-blocks
	  -freorder-functions -falign-functions -falign-jumps -falign-loops
	  -falign-labels -ftree-vrp -ftree-pre
	  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
	  -freorder-blocks -freorder-blocks-and-partition -fprefetch-loop-arrays
	  -ftree-vect-loop-version

endchoice

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
	  the target filesystem.

	  WARNING: This is highly experimental at the moment.

config BR2_HAVE_DOCUMENTATION
	bool "documentation on the target"
	help
	  Install the documentation, including manual pages and info
	  pages, on the target.
	  If you say n here, your target will not contain any
	  documentation.

config BR2_HAVE_DEVFILES
	bool "development files in target filesystem"
	help
	  Install headers and static libraries in the
	  target filesystem

config BR2_PACKAGE_OVERRIDE_FILE
	string "location of a package override file"
	default "$(TOPDIR)/local.mk"
	help
	  A package override file is a short makefile that contains
	  variable definitions of the form <pkg>_OVERRIDE_SRCDIR,
	  which allows to tell Buildroot to use an existing directory
	  as the source directory for a particular package. See the
	  Buildroot documentation for more details on this feature.
