the same say the "test" instruction does in overflow cases, so eliminating the test is only safe when those bits aren't needed, as is the case for COND_E and COND_NE, or if it can be proven that no overflow will occur. For now, just restrict the optimization to COND_E and COND_NE and don't do any overflow analysis. llvm-svn: 66318 |
