Chip Davis	7dcfed888a	Use a hook to emit a local for the sample position. ... That way, we don't have to handle it specially when constructing a call.	2018-09-17 11:51:09 -05:00
Chip Davis	39bc101e82	MSL: Handle the SamplePosition builtin. ... This is somewhat tricky, because in MSL this value is obtained through a function, `get_sample_position()`. Since the call expression is an rvalue, it can't be passed by reference, so functions get a copy instead. This was the last piece preventing us from turning on sample-rate shading support in MoltenVK.	2018-09-13 09:34:28 -05:00
