I don't know anything about Ada. Can you convert the testcase into C?

It does work for me. What is the version of your host Ada compiler? On the
machine I used to bootstrap 109969 it is:
$ gnatls -v
GNATLS 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9)
...
mkdir -p ada/bldtools/nmake_b

/n/05/guerby/trunk-109969/gcc/ada/xnmake.adb ada/bldtools/nm\
ake_b
(cd ada/bldtools/nmake_b; gnatmake -q xnmake ; ./xnmake -b ../../nmake.adb )
mkdir -p ada/bldtools/nmake_s

I think it is a latent bug. When I added -mtune=k8 with revsion 109969, I got
the same failure on c34006a. Laurent, can you verify it as well as cc1226b?
Why do we only see it in Ada?

This is very strange. Even without the -mtune=generic patch, c34006a fails on
Linux/i686 with -Os, -mtune[i386 i486 pentium k6 athlon k8 pentium4 nocona].
Laurent, do you know why?

I have verified that c34006a and cc1226b are only new failures when -mtune=k8
is used.

This might be another manifestation of the argument saving area with
-maccumulate-outgoing-args
(if it is so, either -fno-tree-ter or -mno-accumulate-outgoing-args should
solve it). I will try to look into it tonight as well.

I am not sure -mno-accumulate-outgoing-args -fno-tree-ter will solve the
problem.

Jan, I have verified that turn on x86_partial_reg_stall:
const int x86_partial_reg_stall = m_PPRO;
fixes those 2 failures. That is why only -mtune=pentiumpro passes those
2 tests. Does it ring any bells to you?

It does not :( I will get to machine with Ada compiler only tonight, but
I will try to review the PARTIAL_REG_STALL code, perhaps there is
something obvious.

I fixed the -maccumulate-outgoing-args/-fno-tree-ter issue for 4.1 though.

Very good catch! Here is C testcase. I need to setup testing, then I
will try to debug the problem in combiner.
Honza
struct a

int a;
char b,c,d,e;
};
__attribute__ ((noinline))
__attribute__ ((regparm(1))) t(struct a a)
{

a.c=1;
a.a=1;
a.b=1;
