* Include the use kind along with the expression in the key of theDan Gohman2010-06-191-2/+28
| | | | | | | | | | | | use sharing map. The reconcileNewOffset logic already forces a separate use if the kinds differ, so incorporating the kind in the key means we can track more sharing opportunities. More sharing means fewer total uses to track, which means smaller problem sizes, which means the conservative throttles don't kick in as often. llvm-svn: 106396
* Don't include things in anonymous namespaces that don't need it.Dan Gohman2010-06-191-0/+4

* simplify-libcalls: fold strncmp(x, y, 1) -> memcmp(x, y, 1)Benjamin Kramer2010-06-161-0/+3
| | | | | | | The memcmp will be optimized further and even the pathological case 'strstr(x, "x") == x' generates optimal code now. llvm-svn: 106097

This fixes a bug where LSR was failing to recognize ICmpZero uses, which led it to be unable to reverse the induction variable in the attached testcase. Delete test/CodeGen/X86/stack-color-with-reg-2.ll, because its test is extremely fragile and hard to meaningfully update. llvm-svn: 104262
