I am working on Mips32 -4Kc processor. when i cross-compile the C-code on linux using "mipsel-linux-gcc" toolchain and observe the listing (assembly) , it is not using the features of the Mips32 -4Kc instructions, but using only MIPS-I ISA instruction set.
I even used "-Wa,-mips2 -Wa,-mips32 -Wa,-march=4Kc " option as: mipsel-linux-gcc -S -Wa,-mips2 -Wa,-mips32 -Wa,-march=4Kc main.c
But i want to get my C-code get cross-compiled with all features of the Mips32 -4Kc instructions (like CLZ, CLO, MOVN, MOVZ, MADD MSUB ) for better performance.
Can this be done??
