Bill Hollings	ec054dad7f	MSL: Support synthetic functions in function constants. Emit synthetic functions before function constants. Support use of spvQuantizeToF16() in function constants for numerical behavior consistency with the op code. Ensure subnormal results from OpQuantizeToF16 are flushed to zero per SPIR-V spec. Adjust SPIRV-Cross unit test reference shaders to accommodate these changes. Any MSL reference shader that inclues a synthetic function is affected, since the location it is emitted has changed.	2021-09-28 19:10:16 -04:00
Chip Davis	1264e2705e	MSL: Cast broadcast booleans to ushort. Metal doesn't support broadcasting or shuffling boolean values, but we can work around that by casting it to `ushort`, then casting it back to `bool`. I used `ushort` instead of `uint` because 16-bit values give better throughput on Apple GPUs.	2020-10-23 21:55:46 -05:00

MSL: Support synthetic functions in function constants.

Emit synthetic functions before function constants.
Support use of spvQuantizeToF16() in function constants for numerical
behavior consistency with the op code.
Ensure subnormal results from OpQuantizeToF16 are flushed to zero per SPIR-V spec.

Adjust SPIRV-Cross unit test reference shaders to accommodate these changes.
Any MSL reference shader that inclues a synthetic function is affected,
since the location it is emitted has changed.
