			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

			  -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
