[X86][Clang] VectorExprEvaluator::VisitCallExpr / InterpretBuiltin - allow SSE/AVX FP MAX/MIN intrinsics to be used in constexpr #169991
Description
There are a lot of x86-specific behaviours to handle here, so this initial patch should ONLY handle normal FP values (DENORMAL/INF/NAN/etc. should fail).
However the +/-0.0 special case must be handled straight away - if both operands are zero (any sign) then the second operand 'b' is returned.
We should probably introduce a interp__builtin_elementwise_fp_binop / EvaluateFpBinOpExpr callback handler mechanism for these to InterpretBuiltin / VisitCallExpr respectively.
