X-Git-Tag: v3.10-rc1~15^2^2~8 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3e9f37e885f22e703ec6fe730eba4aebdb5dd5e0;p=profile%2Fivi%2Fkernel-x86-ivi.git MIPS: microMIPS: Optimise 'strnlen' core library function. Optimise 'strnlen' to use microMIPS instructions and/or optimisations for binary size reduction. When the microMIPS ISA is not being used, the library function compiles to the original binary code.
