------- Comment #2 from pinskia at gcc dot gnu dot org  2009-07-01 04:22 -------
Confirmed, simple testcase:
void f(int *a, float b)
{
  *a = b;
}
--- CUT ---
This produces:
_f:
        fctiwz f1,f1
        stfiwx f1,r0,r3
        blr

But it should produce:
_f:
        fctiwz f1,f1
        stfiwx f1,0,r3
        blr

I wonder why %y changed behavior to print out r0 instead of just 0.

This change:
        if (GET_CODE (tmp) == REG)
-         fprintf (file, "0,%s", reg_names[REGNO (tmp)]);
+         fprintf (file, "%s,%s", reg_names[0], reg_names[REGNO (tmp)]);

The patch in comment #3 (with - for new and + for old) applied on top of
revision 148955 seems to fix the problem (currently building libjava).

Thanks Andrew.

------- Comment #8 from dominiq at lps dot ens dot fr  2009-07-04 14:20 -------
I have posted at http://gcc.gnu.org/ml/gcc-testresults/2009-07/msg00317.html
the test results for revision 149193.  There are new failures for which I'll
open PRs ASAP (if nobody is quicker).

Before closing this PR as fixed, could someone document what is the Darwin
peculiarity needing the patch in comments #3 and #6?

------- Comment #9 from jsm28 at gcc dot gnu dot org  2009-07-29 22:47 -------
Darwin not using (a non-ancient version of) the GNU assembler is sufficient
explanation for any assembler syntax issue appearing there but not on other
targets.  Closing as fixed.
