I am trying to inspect the generated assembly for a function in the kernel. Are there any documents explaining how to do this? I want to see how it changes when I change the function body.
The same exact way you'd do it for any .o file for userspace.
objdump and gdb are your friends.
OK :) I did the following: Add -fverbose-asm to CFLAGS and then use objdump -d file.o > d.txt I hope this is right. Suggestions for other better methods welcome :) -- Andev
