gallium/ttn: don't upset nir_validate w/ BRK's
Previously we were unconditionally doing ttn_get_src() even for instructions with no src's. Which created a lot of unnecessary load_const instructions. These were mostly harmless since NIR opt passes would strip them back out. But for an ENDIF following a BRK, it would result in load_const instructions created after the NIR break instruction. Which nir_validate dislikes. But we can actually just dtrt by using NumSrcRegs instead. Signed-off-by: Rob Clark <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
