another testcase, probably better
copied from gcc/testsuite/gcc.dg/tree-ssa/gen-vect-32.c (gen-vect-2.c fails the
same way), but removed headers to prevent confusion
Issue is the same, reading value before store:
...
cmpb $5, 1(%esp) #, s.ca
movdqa .LC0, %xmm0 #, tmp78
movdqa %xmm0, (%esp) # tmp78,
jne .L2 #,
...
Command line:
gcc -O3 -fsched2-use-superblocks -m32 && ./a.out
flags can be changed to:
-O1 -fpeel-loops -fschedule-insns2 -ftree-vectorize -fsched2-use-superblocks
-m32
This testcase fails in 4.4.3 too (but 4.3.4 works)

Um, how can r138953 be the reason when (as the original report says) it's
still okay with r153685? In any case, my patch just shuffled around the
activation/non-activation of the scheduler, so if at all it exposed a latent
bug in it, which given that -fsched2-use-superblocks isn't used by default
is very likely.

I am sorry for the confusion. The original testcase from comment #1 doesn't
fail in r153685 and 4.4.3. Later I found different testcase (comment #2) that
fails there.

------- Comment #7 from hjl dot tools at gmail dot com 2010-05-02 20:09 -------
It is a bug in true_dependence. We get
Breakpoint 7, true_dependence (mem=0x7ffff19246d8, mem_mode=SImode,
x=0x7ffff1924918, varies=0x93bbea <rtx_varies_p>)
at /export/gnu/import/git/gcc/gcc/alias.c:2360
2360 x_addr = get_addr (XEXP (x, 0));
(mem/s/j:QI (plus:SI (value:SI 7:7854 @0x17f5800/0x17f56a0)
(const_int 1 [0x1])) [0 s.ca+1 S1 A8])
(mem:SI (value:SI 7:7854 @0x17f5800/0x17f56a0) [0 *vect_ps.7_1+0 S4 A32])
(gdb)
(gdb) call debug_rtx (x_addr)
(plus:SI (value:SI 7:7854 @0x17f5800/0x17f56a0)
(const_int 1 [0x1]))
(gdb) call debug_rtx (mem_addr)
(plus:SI (value:SI 5:3935 @0x17f57d0/0x17f5640)
(const_int -16 [0xfffffffffffffff0]))
(gdb)
We think x and mem don't overlap. It is clearly wrong.
