------- Comment #3 from rguenth at gcc dot gnu dot org 2008-05-03 09:50 -------
Confirmed. Reduced testcase that fails with -O2 -fPIC:
typedef struct {
volatile unsigned int lock;
int pad0_;
} mutex_t;
struct malloc_state {
mutex_t mutex;
};
static struct malloc_state main_arena;
static __inline__ void mutex_lock(mutex_t *m)
{
int r;
for(;;)
__asm__ __volatile__ ("xchgl %0, %1"
: "=r"(r), "=m"(m->lock)
: "0"(1), "m"(m->lock)
: "memory");
}
void __malloc_check_init()
{
mutex_lock(&main_arena.mutex);
}
4.3.0 seems to work (yes, with checking enabled).

------- Comment #7 from ubizjak at gmail dot com 2008-05-05 10:53 -------
validate_unshare_change was introduced by:
2007-06-26 Jan Hubicka <jh@suse.cz>
* fwprop.c (try_fwprop_subst): Use validate_unshare_change.
* postreload.c (reload_cse_simplify_set): Instead of copying the rtx
early use validate_unshare_change.
(reload_combine): Likewise.
* recog.c (change_t): New field unshare.
(validate_change_1): Rename from validate_change; add argument unshare.
(validate_change): Turn into wrapper of validate_change_1; update
prototype for bools.
(validate_unshare_change): New.
(confirm_change_group): Unshare changes if asked for; avoid unnecesary
calls of df_insn_rescan.
* recog.h (validate_change): Replace ints by bools.
(validate_unshare_change): Declare.
The problem is, that validate_unshare_change logic creates sharing violation if
the same RTX is propagated into two places in the same insn pattern.

This is not a good solution, since the problem is in
"if (SWAPPABLE_OPERANDS_P (x))"
section, a couple of lines down the code. The patch and an analysis is at patch

------- Comment #13 from steve49152 at yahoo dot ca 2008-05-31 02:53 -------
I have tested the fix as backported to 4.2.4 and everything seems fine. I
additionaly discovered code-generation errors in XFree86 4.7.99.17 in the i810
driver which are resolved with the changes. As an extra test I have compiled
XFree86 with the following options:
/system/devel/bin/gcc-4.2.4 -march=pentium3 -mtune=pentium3 -mfpmath=sse,387
-mno-tls-direct-seg-refs -O2 -Wall
Everything works as expected. I'm now recompiling glibc and expect no
surprises.
Thanks people.
