Since we can emit vzeroupper now, we will wait for LRA.
Uros.
Will we wait for LRA commit or is it possiple to commit to trank
vzeroupper patch now?

I tried to perform vzeroupper emitting after reload as additional pass
of mode switching.
I sow one problem that I don't know haw to overcome. After
'pro_and_epilogue', there can be no
flow edge to exit block and pre_exit block is not created in this case
(see rotine create_pre_exit).
Without that

Hi Ricard,
You are right I no need the changes in mode-switchig.c at all. After I
remove additional argument from EMIT_MODE_SET and run 'make check' I
found no differences with make check result of previous run. So I no
need in any changes in the middle end part.

Vladimir
P.S. I'll be

Is there any more comments? Can it be committed in trank?

I'm not sure I understand why you need to know the instruction.

Additionaly.
You can find the patch history in
http://gcc.gnu.org/ml/gcc-patches/2012-08/msg01590.html.
I need this changes for my implementation of vzeroupper placement:
for some statements I have no needs doing real insertion.
I tested the changes on bootstrap using config
../gcc/configu
Hello,
I reproduced the failure and found reason of it. I understood haw it

Thank you,

Thank you for testing.

I changed type of transp and added this checking because if we reset
transp[mode], then later in the loop
FOR_EACH_BB (bb)
sbitmap_not (kill[bb->index], transp[i][bb->index]);
we set kill of the bb for that
