================ Comment at: cfe/trunk/include/clang/Basic/LangOptions.def:220 +/// \brief FP_CONTRACT mode (on/off/fast). +ENUM_LANGOPT(DefaultFPContractMode, FPContractModeKind, 2, FPC_Off, "FP contraction type") LANGOPT(NoBitFieldTypeAlign , 1, 0, "bit-field type alignment") ---------------- This change seemed to cause some performance degradations in some OpenCL applications. This option used to be on by default. Now it is off by default. There are applications do separated compile/link/codegen stages. In the codegen stage, clang is invoked with .bc as input, therefore this option is off by default, whereas it was on by default before this change. Is there any reason not to keep the original behavior? Thanks.
