tgsi: handle some src/dst aliasing in tgsi_sse2.c Src/Dst aliasing (aka SOA dependencies) requires some care to ensure intermediate results do not overwrite yet-to-be read source registers. This change ensures that MOV/SWZ handle this correctly, which is poor but no worse than the current tgsi_exec.c path. Remove the fallback as there is nothing to be gained correctness-wise between the two implementations now. Fixing this properly looks like a bit of work in this code, but might be easily achieved by sending destination writes to temporary storage. 2009-09-13 11:59:24 -07:00			`!!ARBfp1.0`
