Confirmed with gcc 3.2. With gcc 3.3 (branch) on i686-linux and Christian's testcase, I get:
/tmp/ccS0QCPS.s: Assembler messages:
/tmp/ccS0QCPS.s:20: Error: suffix or operands invalid for `lea'
With mainline, the testcase compiles and assembles fine.
On cross-compiler to SPARC, Christian's testcase compiles fine with gcc 3.3 branch and mainline
(20030604).
Does this mean this bug has been fixed? Thanks,
Dara

Ah. This is why I thought it had already been done. Maybe you want
to poke Alan Modra about the research he said he would do?

I made the following reply the day after I said I'd poke around. Somehow it
seems to be missing from the gcc-patches archive. Anyway, here it is again:
I grepped through the entire slackware linux source base for occurrences
of __PIC__, and found that all those that might affect PowerPC64 were
testing for (b). There were only three occurrences, all in glibc! Many
more for x86 which I didn't pay much attention to, but the few I did
look at were actually testing for (a). This isn't so surprising, since
on x86 we want different assembly for PIC code, regardless of whether
PIC code is for shared libs (most likely) or otherwise. OTOH, the
only sensible test of __PIC__ on PowerPC64 can be for (b), since we
are (a) all the time.
Because we currently define __PIC__ all the time, the three occurrences
affecting PowerPC64 Linux result in missed optimizations for non-shared
lib code.
This suggests that powerpc64-linux-gcc should only define __PIC__ when
-fPIC is given, and that Kaveh's patch is OK.

No, actually not the next day, but a few days later. Incidentally, the (a) and
(b) are from an earlier reply of mine on this subject:
On most other targets, -fpic, ie. flag_pic, means two things:
a) generate PIC code, and
b) generate code suitable for ELF shared libraries.
I'll not argue the wisdom of -fpic meaning two things, but that's just
how things evolved. On PowerPC64, code generation is always PIC, but we
don't want the overhead of meeting shared library run-time symbol
resolution requirements when generating application code. Thus, we
don't want to set flag_pic all the time.
