--- Comment #20 from Jack Howarth <howarth at nitro dot med.uc.edu> 2010-11-10 05:12:10 UTC ---
The new gcc.target/i386/alias-1.c testcase produces...

FAIL: gcc.target/i386/alias-1.c (test for excess errors)
FAIL: gcc.target/i386/alias-1.c scan-assembler wobbly
FAIL: gcc.target/i386/alias-1.c scan-assembler jelly

at -m32 on x86_64-apple-darwin10 with errors of the form...

warning: alias definitions not supported in Mach-O; ignored [enabled by
default]^M

Shouldn't this testcase contain...

/* { dg-require-alias "" } */

which will convert it to an unsupported test as was done for
gcc.dg/lto/20081222_0.c on darwin?
