rjmccall added a comment. I think on balance the right thing to do is probably to add an alternative to `-fexcess-precision`, like `-fexcess-precision=none`. We can default to `-fexcess-precision=standard` and treat `-fexcess-precision=fast` as an alias for `standard` for now.
================ Comment at: clang/docs/LanguageExtensions.rst:746 * SPIR -* X86 (Only available under feature AVX512-FP16) +* X86 (Enabled with feature SSE2 and up) ---------------- Note that I'm not trying to propose this specific name for the option; I'm just saying that, if we provide a way to control this, it should be documented here as the central place we document Clang's `_Float16` support. ================ Comment at: clang/lib/CodeGen/CGExprComplex.cpp:934 + return ComplexExprEmitter(*this).EmitPromoted(E, DstTy); +} + ---------------- `EmitPromotedComplexExpr` should look like `EmitPromotedScalarExpr`, i.e. it should start with an expression, check for the arithmetic cases where we directly support promoted emission, and otherwise emit the unpromoted pair and then promote it.
