History
Bill Wendling 7d9f2b93a3 This test case: 
long test(long x) { return (x & 123124) | 3; }

Currently compiles to:

_test:
        orl     $3, %edi
        movq    %rdi, %rax
        andq    $123127, %rax
        ret

This is because instruction and DAG combiners canonicalize

  (or (and x, C), D) -> (and (or, D), (C | D))

However, this is only profitable if (C & D) != 0. It gets in the way of the
3-addressification because the input bits are known to be zero.

DebugInfo Remove test to check bugfix in handing debug info for global variables using intrinsics. Now, debug info for global variable is encoded using metadata. The old code path is now history and there is no need to have a test to check a bug fix in old code path. 2010-03-01 19:09:55 +00:00
