Hi Shivarama,
Could you please also file a bug (if there isn't one) and attach the test case
to the bugzilla before you check in this patch? So that you can refer the bug
number when you submit the patch. Thank you very much.

Hi,
Could a gatekeeper please review the following changes, which would fix cmake
build under Open64?
The hyperblock scheduler makes the following transformation, which is
incorrect in 64 bit mode.
From:
addl $1,%edx
movsbl 0(%rdx,%r9,1), %eax
To:
movsbl 1(%rdx,%r9,1), %eax
addl $1,%edx
In the test environment $edx value is initially -1 and the address computed
for movsbl would have been 0+0+r9*1. With the above optimization, the address
computed is 1+0xffff+$r9*1 which is incorrect. The fix disallows the above
transformation in 64 bit mode when add is a 32 bit instruction.

Shivaram
