Thank you, Jakub.
The following patch passed bootstrap, gcc make check and spec2000 with
-p -m32 -fPIC.
Is it ok?

Agree. Let't stop at first insn after entry block notes.
As for the test it looks like mcount is general i?86 name.
Bootstrap and make check are in progress.

The following patch align stack for mcount and there should be no
problems with unwind as ix86_frame_pointer_required is true when
crtl-profile is true and flag_fentry is false (we call mcount after
function prolog).
When flag_fentry is true it is set to false in 32bit PIC mode:

What is wrong in emitting the set_got right before the PROLOGUE_END
note and that way sharing a single load from both?
Can you please explain the idea? Now set_got emitted right after
PROLOGUE_END, what is the advantage in emitting it right before?
Which load is going to be shared?
This looks

Hi,
The patch fixes profile in 32bits PIC mode (only -p option affected).
x86 bootstrap, make check passed
spec2000 o2 -p train data on Corei7:
CINT -5%
CFP +1,5
compared to a compiler before enabling ebx.
There is a potential performance improve after the patch applied
suggested by Jakub:
