[PATCH 4/4] MIPS: Optimise core library function 'strnlen' for microMIPS.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Steven J. Hill" <sjhill@xxxxxxxx>

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.
