* nir: Add a function to detect if a block is immediately followed by an ifJason Ekstrand2015-01-154-13/+30
| | | | | | | | Since we don't actually have an "if" instruction, this is a very common pattern when iterating over instructions. This adds a helper function for it to make things a little less painful. Reviewed-by: Connor Abbott <[email protected]>

* nir: Add a naieve from-SSA passJason Ekstrand2015-01-153-0/+195
| | | | | | | This pass is kind of stupidly implemented but it should be enough to get us up and going. We probably want something better that doesn't generate all of the redundant moves eventually. However, the i965 backend should be able to handle the movs, so I'm not too worried about it in the short term.

* i965/fs: Don't take an ir_variable for emit_general_interpolationJason Ekstrand2015-01-154-35/+41
| | | | | | | | | | Previously, emit_general_interpolation took an ir_variable and pulled the information it needed from that. This meant that in fs_fp, we were constructing a dummy ir_variable just to pass into it. This commit makes emit_general_interpolation take only the information it needs and gets rid of the fs_fp cruft. Reviewed-by: Connor Abbott <[email protected]>
