Chip Davis	2a9091ce53	MSL: Use `rint()` instead of `round()` to round array coordinates. Vulkan specifies round-to-nearest-even mode to round array coordinates. But we were using `round()`, which is round-to-nearest-away-from-zero. Instead, use `rint()`, which is specified to perform nearest-even rounding in MSL.	2023-01-18 19:34:29 -08:00
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

MSL: Use rint() instead of round() to round array coordinates.

Vulkan specifies round-to-nearest-even mode to round array coordinates.
But we were using `round()`, which is round-to-nearest-away-from-zero.
Instead, use `rint()`, which is specified to perform nearest-even
rounding in MSL.
