Lioncash c41b5a3492 x64/reg_alloc: Use type alias for array returned by GetArgumentInfo() 
This way if the number ever changes, we don't need to change the type in
other places.
 2020-04-22 20:46:23 +01:00
Lioncash 2188765e28 ir/value: Use type alias CoprocessorInfo for std::array<u8, 8> 
Provides a more descriptive label for the interface, and avoids the need
to hardcode the array size in multiple places.

Lioncash 54d8552177 a32_emit_x64: std::move A32::UserConfig in the constructor 
This avoids a few redundant atomic increments and decrements,
considering the UserConfig instance contains a std::array of
std::shared_ptr<Coprocessor> instances.

MerryMage 8ef195db3c emit_x64_floating_point: DenormalsAreZero is redundant as hardware already does DAZ

MerryMage b393e15ab6 backend_x64: Fix bugs when FPCR.FZ=1 
Bugs:
* DenormalsAreZero flushed to positive zero instead of preserving sign.
* FMAXNM/FMINNM (scalar) should perform DAZ *before* special zero handling.
* FMAX/FMIN/FMAXNM/FMINNM (vector) did not DAZ.
