| FPOpFusion::FPOpFusionMode llvm::TargetOptions::AllowFPOpFusion = FPOpFusion::Standard |
AllowFPOpFusion - This flag is set by the -fp-contract=xxx option.
This controls the creation of fused FP ops that store intermediate results in higher precision than IEEE allows (E.g. FMAs).
Fast mode - allows formation of fused FP ops whenever they're profitable. Standard mode - allow fusion only for 'blessed' FP ops. At present the only blessed op is the fmuladd intrinsic. In the future more blessed ops may be added. Strict mode - allow fusion only if/when it can be proven that the excess precision won't effect the result.
Note: This option only controls formation of fused ops by the optimizers. Fused operations that are explicitly specified (e.g. FMA via the llvm.fma.* intrinsic) will always be honored, regardless of the value of this option.

FloatABIType - This setting is set by -float-abi=xxx option is specfied on the command line.
This setting may either be Default, Soft, or Hard. Default selects the target's default behavior. Soft selects the ABI for software floating point, but does not indicate that FP hardware may not be used. Such a combination is unfortunately popular (e.g. arm-apple-darwin). Hard presumes that the normal FP ABI is used.
