2021-06-03softfloat: Introduce Floatx80RoundPrecRichard Henderson1-2/+3

2020-08-21softfloat: pass float_status pointer to pickNaNMax Filippov1-0/+5
Pass float_status structure pointer to the pickNaN so that machine-specific settings are available to NaN selection code. Add use_first_nan property to float_status and use it in Xtensa-specific pickNaN.

2020-08-21softfloat: make NO_SIGNALING_NANS runtime propertyMax Filippov1-0/+5
target/xtensa, the only user of NO_SIGNALING_NANS macro has FPU implementations with and without the corresponding property. With NO_SIGNALING_NANS being a macro they cannot be a part of the same QEMU executable. Replace macro with new property in float_status to allow cores with different FPU implementations coexist.

2020-05-19softfloat: Name rounding mode enumRichard Henderson1-2/+3
Give the previously unnamed enum a typedef name. Use the packed attribute so that we do not affect the layout of the float_status struct. Use it in the prototypes of relevant functions. Adjust switch statements as necessary to avoid compiler warnings.

2019-08-19fpu: move inline helpers into a separate headerAlex Bennée1-0/+132
There are a bunch of users of the inline helpers who do not need access to the entire softfloat API. Move those inline helpers into a new header file which can be included without bringing in the rest of the world.
