AFAIK -O0 compiles OK, -O1 fails and cause internal compiler error.

------- Comment #8 from rguenth at gcc dot gnu dot org  2009-08-31 12:45 -------
Confirmed.

class QString { };
QString fixString(QString string);
static QString fixPathToLocalOS(const QString &in)                             
{ 
  return fixString(in);
}
void __attribute__((__optimize__ ("0")))
foo(void) { }
void runQMake(QString pfile)
{ 
  fixPathToLocalOS(pfile);
}


triggered by __attribute__((__optimize__ ("0"))) on the unrelated function foo.

Mike, this is yours.

[jakub at gcc dot gnu dot org]

------- Comment #9 from jakub at gcc dot gnu dot org  2009-08-31 14:32 -------
The problem is that the optimization saving/restoring infrastructure seems to
ignore OVERRIDE_OPTIONS.  i386 OPTIMIZATION_OPTIONS sets flag_pcc_struct_return
to 2 and expects OVERRIDE_OPTIONS to set it to 0 resp. 1 if it is still 2, but
as OVERRIDE_OPTIONS isn't called, it remains set to 2, which is treated as if
it was 1.

Target optimization has many issues. See PR 37565.

------- Comment #11 from jakub at gcc dot gnu dot org  2009-09-01 09:32 -------
Mark, I don't think this should be P1, __optimize__ attribute is new in 4.4 (so
considering it regression is already quite weird, though the attribute is
ignored in older releases, so technically it is a regression, albeit one
wouldn't use it with pre-4.4), but more importantly is known to be broken in
many ways.

[mmitchel at gcc dot gnu dot org]

------- Comment #12 from mmitchel at gcc dot gnu dot org  2009-09-01 13:54 -------
I think the question is whether the use of __optimize__ is in a standard Qt
release.  If it is, then I'm quite concerned; it's bad if GCC 4.4.2 can't build
Qt/KDE.

(TBH, I'm concerned anyhow; if __optimize__ is unreliable, then perhaps we
should be ignoring/warning about it in 4.4.x until we get it solid...)

Hmm I haven't noticed this bug has been fixed a week ago, since [Revision
151627], it was still reproducible at [Revision 151584] which was just a day
before.
Thanks!!
