This might be a bug in Apple's assembler.

Jack,

Did Apple give any reply on this. Is this their bug? If so we better close the
gcc bug as invalid.

No official response yet although Mike Stump agrees that it is probably a bug
in their assembler.

I think its reasonable to close this bug as invalid, do you agree? Meanwhile we
can bug Apple Gcc guys to take a stab at this.

Thanks,

------- Comment #9 from dominiq at lps dot ens dot fr  2008-09-26 07:34 -------
With Xcode 3.1.1 all the failures disappeared but
gcc.target/i386/sse4_2-popcntl.c:

FAIL: gcc.target/i386/sse4_2-popcntl.c (test for excess errors)
WARNING: gcc.target/i386/sse4_2-popcntl.c compilation failed to produce
executable

The error is:

[ibook-dhum] f90/bug% gcc44 -m64 -O2 -msse4.2
/opt/gcc/_gcc_clean/gcc/testsuite/gcc.target/i386/sse4_2-popcntl.c
/var/folders/iU/iUj3xngxGYe3MPCc0TZUcE+++TI/-Tmp-//ccsFk4uR.s:31:suffix or
operands invalid for `popcnt'

and the offending line in assembly code is:

        popcntl %edx, %eax

Dominique,
    The remaining failure in the sse4_2-popcntl.c testcase has been reported
for awhile on radar (ID 5650346). Like the previous errors these are most
likely assembler bugs.

Jack,

Did you get any feedback from Apple saying that the other previous errors have
been fixed? (I think they were not in Xcode 3.1.0).

No, I never got a message that any of the originally reported sse4 gcc test
cases
were fixed. I simply noticed it during testing. The radar report is still open
though. Feel free to open a duplicate to try to ping the Apple cctools
developers on this issue.
