Between LAST_UPDATED: "Thu Feb 24 08:05:18 UTC 2005"
and "Thu Feb 24 14:59:24 UTC 2005" I see lots of testsuite regressions.
For GCC, they are (as per Mike Stump's script):
Tests that now fail, but worked before:
21_strings/basic_string/insert/char/2.cc execution test
21_strings/basic_string/replace/char/3.cc execution test
22_locale/money_get/get/char/14.cc execution test
22_locale/money_get/get/char/6.cc execution test
23_containers/vector/check_construct_destroy.cc execution test
23_containers/vector/invalidation/3.cc execution test
25_algorithms/sort.cc execution test
Tests that now fail, but worked before:
gcc.c-torture/execute/20010124-1.c execution, -O0
gcc.c-torture/execute/20010124-1.c execution, -O1
gcc.c-torture/execute/20010124-1.c execution, -O2
gcc.c-torture/execute/20010124-1.c execution, -Os
(also failures in newlib sanity tests).
It seems that the cause is that memmove is miscompiled.
Here's a slightly minimized test-case. Note the use of asm-declared registers:
void *x (void *pdst, const void *psrc, unsigned int pn)
{
register void *return_dst __asm__ ("r10") = pdst;
register unsigned char *dst __asm__ ("r13") = pdst;
register unsigned const char *src __asm__ ("r11") = psrc;
register int n __asm__ ("r12") = pn;
if (src < dst && dst < src + n)
{
src += n;
dst += n;
while (n--)
*--dst = *--src;
return return_dst;
}
while (n >= 16) n--;
return return_dst;
}
extern void abort ();
extern void exit (int);
char xx[30] = "abc";
int main (void)
{
char yy[30] = "aab";
if (x (xx + 1, xx, 2) != xx + 1 || memcmp (xx, yy, sizeof (yy)) != 0)
abort ();
exit (0);
}
The moving while-loop results in this code (pruned;
assembly syntax should be understandable enough knowing that
destinations are to the right):
_x:
cmp.d $r11,$r10
bls .L2
nop
add.d $r12,$r11
cmp.d $r11,$r10
blo .L14
move.d $r10,$r9

.size _x, .-_x
Note the absence of update of R12.

I find this very hard to believe. The only thing this patch did is move
text around the file. It added no code and removed no code.

I've had this patch in TCB for over 3 weeks now, but don't worry, I'll
take a peek tomorrow.

Could you show me how to configure a cris-axis-elf target and build a simulator?
Have you tried undoing the tree-into-ssa.c change? It should be easy with:
$ cvs up -r 2.40 tree-into-ssa.c
If there had been a bug in the tree-into-ssa.c changes we would be seeing
widespread carnage on every target. And that is just not the case:

In response to comment #6:
Building a CRIS toolchain with simulator (but see further below):
The general steps are exactly as any other simulator target,
follow <URL:http://gcc.gnu.org/simtest-howto.html>, though you need
the cris-sim.exp as per
<URL:http://gcc.gnu.org/ml/gcc-bugs/2005-02/msg00138.html>
(now in dejagnu CVS; not on sourceware). Because the baseboard file
is not in the installed dir, special steps are necessary:
"mkdir ~/dejagnuboards"
Put cris-sim.exp in ~/dejagnurc
"echo 'set boards_dir ~/dejagnuboards' > ~/.dejagnurc"
Then proceed as per simtest-howto.html
But you actually just need to build cc1 and observe the assembly I posted.
And again, I think I need to point out that a bug in handling of
*asm-declared registers* is unlikely to show "widespread carnage".
But I certainly see how it can be overlooked and broken in tree-ssa
cleanup operations!
I have not tried reverting the patch but will do later, hoping it can
convince you that the "reorganization" caused this regression (whether
directly or indirectly exposing bugs elsewhere).

I was lucky enough to have a source tree from just before the suspected change
in the machine where I test using geoffk's script. (It's a RH9 machine as
opposed to FC2, so thus we can supposedly also rule out miscompilation by the
host gcc.) I have updated just the suspected change. Test in progress.

Ah, yes. I see it now. The reorg tickled a bug in the renamer:
# n_21 = V_MUST_DEF <n_18>
n = D.1158_28
...
n_48 = PHI <n_37, n21>
<L2>:
...
# VUSE <n_21>
n.5_40 = n;
That's wrong. The last VUSE should be VUSE <n_48>. Virtual operands should
always be in FUD-chain form.
Working on a fix.
