Subject: switch_to()/doesnt %esp get replaced with %ebp on ret
Date: Mon, 19 Mar 2001 16:19:09 +0300 [thread overview]
Message-ID: <E14ezYx-000J2L-00@f6.mail.ru> (raw)
in schedule(), switch_to() macro changes esp to
the new process's stack. But, on exit frm schedule,
how come it does not get overwritten with ebp-24,
as the dissasembled code shows. The code was compiled
without the -fomit-frame-pointer.
pushl 508(%ecx)
jmp __switch_to
1: popl %ebp
popl %edi
popl %esi
jmp .L1180
.L1180:
leal -24(%ebp),%esp
popl %ebx
popl %esi
popl %edi
movl %ebp,%esp
popl %ebp
ret
