* i965/nir: Validate that NIR passes call nir_metadata_preserve().Kenneth Graunke2015-11-181-0/+5
| | | | | | | | | | | | | | | | | | | | | Failing to call nir_metadata_preserve() can have nasty consequences: some pass breaks dominance information, but leaves it marked as valid, causing some subsequent pass to go haywire and probably crash. This pass adds a simple validation mechanism to ensure passes handle this properly. We add a new bogus metadata flag that isn't used for anything in particular, set it before each pass, and ensure it *isn't* still set after the pass. nir_metadata_preserve will reset the flag, so correct passes will work, and bad passes will assert fail. (I would have made these functions static inline, but nir.h is included in C++, so we can't bit-or enums without lots of casting...) Thanks to Dylan Baker for the idea.

| | | | | | | | | | | | Adds nir_src_is_dynamically_uniform which returns true if the source is known to be dynamically uniform. This will be used in a later patch to add a workaround for cases that only work with dynamically uniform sources. Note that the function is not definitive, it can return false negatives (but not false positives). Currently it only detects constants and uniform accesses. It could easily be extended to include more cases. Reviewed-by: Matt Turner <mattst88@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | This patch also introduces a lowering pass to convert the simple GS intrinsics to the new ones. See the comments above that for the rationale behind the new intrinsics. This should be useful for i965; it's a generic enough mechanism that I could see other drivers potentially using it as well, so I don't feel too bad about putting it in the generic code. v2: - Use nir_after_block_before_jump for the cursor (caught by Jason Ekstrand - I'd mistakenly used nir_after_block when rebasing this code onto the new NIR control flow API). - Remove the old emit_vertex intrinsic at the end, rather than in the middle (requested by Jason). - Use state->... directly rather than locals (requested by Jason). - Report progress from nir_lower_gs_intrinsics() (requested by me). - Remove "Authors:" section from file comment (requested by Michael Schellenberger Costa).
