On a quick find with checksum.S I found these files: ./arch/xtensa/lib/checksum.S ./arch/sh/lib/checksum.S ./arch/m32r/lib/checksum.S ./arch/cris/arch-v32/lib/checksum.S ./arch/cris/arch-v10/lib/checksum.S ./arch/score/lib/checksum.S and then on quick find with checksum.c, I found these fliles: ./arch/h8300/lib/checksum.c ./arch/tile/lib/checksum.c ./arch/alpha/lib/checksum.c ./arch/m68k/lib/checksum.c ./arch/hexagon/lib/checksum.c ./arch/mn10300/lib/checksum.c ./arch/parisc/lib/checksum.c ./arch/frv/lib/checksum.c ./arch/ia64/lib/checksum.c ./arch/c6x/lib/checksum.c ./lib/checksum.c These files seems to be one of tcp/ip/upd checksum routines. if these are the files you are trying to change, then why are you trying to change the format? And how do you know that changing from Assembly to C will improve the efficiency? > > > On Mon, Jan 7, 2013 at 7:09 PM, Anuz Pratap Singh Tomar < > [email protected]> wrote: > >> >> >> On Mon, Jan 7, 2013 at 12:34 PM, SaNtosh kuLkarni < >> [email protected]> wrote: >> >>> Hi is it possible that the assembly code .S file in linux kernel be >>> replaced by a .C file. >>> >>> This seems like a very general question.
