Here are the results of egcs-971127 on powerpc-ibm-aix4.2.1.0.
egcs native configuration with --enable-shared.
Used patches: patch for multithreaded exception handling
by Teemu Torma and my patch for shared libraries support.
Why there is a regression in gcc testsuite
(gcc.c-torture/execute/va-arg-5.c)?

Bug in Meissner's rework of some of Geoffrey Keating's patches;
This should fix the problem (and will be included in the release).

Hmm, this also solves a sig11 while compiling glibc-2.1 for me, but it
didn't change the test behaviour on powerpc-unknown-linux-gnulibc1. The
strange thing is, after getting the sig11 I started applying Geoff's
remaining patches step by step and the following one also prohibited the
sig11. Is Michaels rework really buggy?
BTW, while looking at *.s files generated by -save-temps I noticed that I
can't switch on -mmultiple, it is always directly followed by
-mno-multiple. I tried with various combinations of -mpowerpc,
-mcpu=powerpc, etc. and was never able to get rid of the -mno-multiple.
According to the docs this should be possible. Is there any other option
that forces -mno-multiple?
Anyway, egcs-971127 is now quite fit for release from the Linux/PPC
viewpoint ;-). Thanks all the helpful guys involved in this!
Bye,
Franz.
Patch by Geoff Keating, originally for an older version of egcs, so it
applies with offset:
* PIC code breaks when nested functions are used; for instance, the following
compiled with 'cc1 -O2 -fpic -Wall'. (The -Wall gives a nice visible crash,
rather than quietly generating invalid code.)
extern void x1(int), x2(int);
extern int c1, c2;
void x3 (int p) {
static inline void i1 (void) { x1(c1); }
static inline void i2 (void) { i1(); }
if (p) i2();
x2(c2);
}

Good.

It shouldn't. The change I forwarded to you should not effect ppc-linux
at all.

Yes. It had a real bug.

The way the ppc handles this is a little odd -- basically I don't think you
can depend on the info in the .s file to correctly tell you the right thing
for -mmultiple.

I rewrote this fix to be more correct. You shouldn't need Geoff's fix
for this problem anymore. My version has been in egcs snapshots for
several weeks.

Here are the results of egcs-971127 on powerpc-ibm-aix4.2.1.0.
egcs native configuration with --enable-shared --enable-haifa.
Used patches: patch for multithreaded exception handling
by Teemu Torma and my patch for shared libraries support.
all tests results are the same as without haifa except
g++ results.
