Andrew Brown	3778fa025c	Switch DataValue to use Ieee32/Ieee64 ... As discussed in #2251, in order to be very confident that NaN signaling bits are correctly handled by the compiler, this switches `DataValue` to use Cranelift's `Ieee32` and `Ieee64` structures. This makes it a bit more inconvenient to interpreter Cranelift FP operations but this should change to something like `rustc_apfloat` in the future.	2020-10-07 12:17:17 -07:00

Andrew Brown	6f6f79ef2b	refactor: move DataValue from cranelift-reader to cranelift-codegen ... This is no change to functionality; the move is necessary in order to return InstructionData immediates in a structure way (see next commit).	2020-10-07 12:17:17 -07:00
