Bug #: 50145
Summary: FAIL: gcc.dg/torture/pr50067-*.c -O* execution test on
powerpc*-*-*
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: dominiq@lps.ens.fr
CC: rguenther@suse.de
Host: powerpc*-*-*
Target: powerpc*-*-*
Build: powerpc*-*-*
gcc.dg/torture/pr50067-*.c aborts on powerpc*-*-* (see
http://gcc.gnu.org/ml/gcc-testresults/2011-08/msg02191.html and
http://gcc.gnu.org/ml/gcc-testresults/2011-08/msg02189.html). AFAICT this is
not a regression: they aborts also when compiled with gcc 4.4.6.

Can you please check why? I suppose it's a big/little-endian issue with the
testcase, so the expected array contents change? Making the short input
array values duplicated in both bytes could fix the test (with adjusting
the expected output as well)

> Can you please check why?
Using (note that I am C illiterate;-)
for (i = 0; i < 32; ++i)
printf("%hd ", * (&a[i]));
printf("\n");
before and after
for (i = 0; i < 32; ++i)
(*((unsigned short(*)[32])&a[0]))[i] = (*((char(*)[32])&a[0]))[i+8];
I get on powerpc-apple-darwin9:
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

0 0 0 0 0
instead of
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
22 23 24 25 26 27 28 29 30 31

gcc.dg/torture/pr50067-*.c also aborts on sparc64-linux and m68k-linux.
They're both big-endian platforms.
