Hi all,
I am using gcc -S to generate this assembly code. The compiler
gives:
andl $-16, %esp
I understand that we are here basically anding 0xffff00ff with %esp. But
what I can't get is use of doing this. Could somebody tell me the
significance of doing this.
Detailed code:
pushl %ebp
movl $16, %edx
movl %esp, %ebp
subl $8, %esp
andl $-16, %esp
movl %edx, 4(%esp)
TIA
