The alias scope and type bits are intertwined in the encoding: - bit 47: low scope - bit 48: type - bit 49: high scope - bit 50: type size Combining the low and high scope bits, the value is used as follows: - 0: tex - 1: rt - 2: mem - 3: mem I don't know what the difference between 2 and 3 is. The blob currently doesn't use mem at all. The type bit seems to be used to make a distinction between floating point (f) and integer (b) sources. There doesn't seem to be any functional difference and it only affects how immediates are displayed. Note that I haven't exactly mimicked the blob in these cases: - alias.tex.f16/32: the blob uses b16/32 while printing immediates in floating point notation. I think it make more sense to use f16/32. - alias.rt.b16/32: the blob uses i16/32 here. I think it makes more sense to stick to a single notation (b).
