config NATIVE_TOOLCHAIN
	bool
	prompt "Use host's toolchain" if DEVEL && BROKEN
	default n
	help
		If enabled, OpenWrt will compile using your existing toolchain instead of compiling one

menuconfig TOOLCHAINOPTS
	bool "Toolchain Options" if DEVEL
	depends !NATIVE_TOOLCHAIN

menuconfig EXTRA_TARGET_ARCH
	bool
	prompt "Enable an extra toolchain target architecture" if TOOLCHAINOPTS
	default n
	help
	  Some builds may require a 'biarch' toolchain. This option
	  allows you to specify an additional target arch.

	  Most people will answer N here.

	config EXTRA_TARGET_ARCH_NAME
		string
		prompt "Extra architecture name" if EXTRA_TARGET_ARCH
		help
		  Specify the cpu name (eg powerpc64 or x86_64) of the
		  additional target architecture.

	config EXTRA_TARGET_ARCH_OPTS
		string
		prompt "Extra architecture compiler options" if EXTRA_TARGET_ARCH
		help
		  If you're specifying an addition target architecture,
		  you'll probably need to also provide options to make
		  the compiler use this alternate arch.

		  For example, if you're building a compiler that can build
		  both powerpc and powerpc64 binaries, you'll need to
		  specify -m64 here.

config GDB
	bool
	prompt "Build gdb" if TOOLCHAINOPTS
	default n
	help
		Enable if you want to build the gdb

config LARGEFILE
	bool
	prompt "Enable large file (files > 2 GB) support?" if TOOLCHAINOPTS
	default y
	help
		Enable large file (files > 2 GB) support

config SHADOW_PASSWORDS
	bool
	prompt "Enable shadow password support?" if TOOLCHAINOPTS
	default y
	help
		Enable shadow password support.

config SOFT_FLOAT
	bool
	prompt "Use software floating point by default" if TOOLCHAINOPTS
	default y
	depends on (arm || armeb || powerpc) && !HAS_FPU
	help
	  If your target CPU does not have a Floating Point Unit (FPU) or a
	  kernel FPU emulator, but you still wish to support floating point
	  functions, then everything will need to be compiled with soft floating
	  point support (-msoft-float).

	  Most people will answer N.

config TARGET_OPTIMIZATION
	string
	prompt "Target Optimizations" if TOOLCHAINOPTS
	default "-O2 -pipe -march=i686 -funit-at-a-time" if TARGET_x86_mediacenter

	default "-Os -pipe -funit-at-a-time"
	help
	  Optimizations to use when building for the target host.
