Summary: Altivec code generation error with setjmp
Product: gcc
Version: 3.3.2
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: john dot whitney at timesys dot com
CC: gcc-bugs at gcc dot gnu dot org,john dot whitney at
timesys dot com
GCC build triplet: powerpc-linux
GCC host triplet: i686-linux
GCC target triplet: i686-linux
We are using GCC 3.2 for the PowerPC 74xx to compile the Linux Test Project code (in specific, the
write04 test). I found that the resulting executable was segfaulting. Investigation showed the
following assembly code:
70: 7d 80 42 a6 mfvrsave r12
74: 91 8c ff 20 stw r12,-224(r12)
78: 65 8c df ff oris r12,r12,57343
7c: 61 8c ff ff ori r12,r12,65535
80: 7d 80 43 a6 mtvrsave r12
VRSAVE was 0, so line 74 resulted in a NULL pointer access.
I've come up with a much-reduced test program that exercises this problem:
-------------------
#include <signal.h>
#include <setjmp.h>
#include <limits.h>
static sigjmp_buf jmp;
int main(int argc, char **argv)
{
char wbuf[8 * PIPE_BUF];
if (sigsetjmp(jmp, 1)) {
return 1;
}
return 0;
}
-------------------
This produces the following assembly code:
10000490 <main>:
10000490: 7c 2c 0b 78 mr r12,r1
10000494: 3c 00 ff ff lis r0,-1

100004dc: 7f 6c 01 ce stvx v27,r12,r0
100004e0: 38 00 fe d0 li r0,-304
100004e4: 7f 8c 01 ce stvx v28,r12,r0
100004e8: 38 00 fe e0 li r0,-288
100004ec: 7f ac 01 ce stvx v29,r12,r0
100004f0: 38 00 fe f0 li r0,-272
100004f4: 7f cc 01 ce stvx v30,r12,r0
100004f8: 38 00 ff 00 li r0,-256
100004fc: 7f ec 01 ce stvx v31,r12,r0
10000500: 7d 80 42 a6 mfvrsave r12
10000504: 91 8c ff 20 stw r12,-224(r12)
10000508: 65 8c df ff oris r12,r12,57343
1000050c: 61 8c ff ff ori r12,r12,65535
10000510: 7d 80 43 a6 mtvrsave r12
10000514: 7c 08 02 a6 mflr r0
Again, the zero-containing r12 is used at address 0x10000500. This appears to be caused by the
32k stack variable, wbuf. If that variable is made static, or reduced in size, r1 is used as expected
in the line following mfvrsave, instead of the erroneous r12.
This problem appears in GCC 3.2, and in a test build I made of GCC 3.3.2.

On powerpc-apple-darwin in 3.3.2 (20030908), I get:
mfspr r12,256
stw r12,-224(r1)
oris r12,r12,0xdfff
ori r12,r12,65535
mtspr 256,r12
which looks right.
on the mainline, GCC does not even save the altivec registers at all (why?).

It does.

Why should it save _any_ registers (that are not changed before the call
to setjmp()? setjmp() will just save them again?

Confirmed, I do not know why gcc saves them at all, note that on the mainline now gcc saves the
altivec registers but right.

Gcc no longer saves the FP or altivec registers. See PR 13133 and the patch I
checked in for it in the message

I don't think the actual bug of this report is solved.
Hard to check without a testcase, though ;-)

Can still happen when you use all the altivec registers, segher is working on a fix for that
bug and this is really a target bug.
