From: Rob Clark <robcl...@freedesktop.org> Mostly the implementation of nir_shader_clone() for copying a NIR shader IR, plus couple cleanups, reference counting, and helper macros. The reference counting will be useful for mesa-st (and perhaps other state trackers), since there are cases when both mesa-st and the driver need to hold on to copies to do their own variant management.
Couple small TODO's still.. The clone-test (NIR_TEST_CLONE=1, which clones/revalidates/replaces the shader between each opt/lowering pass) survives glmark2. I need still to subject it to a piglit run. I was originally going to use nir_cf_node_insert()/nir_instr_insert() with the plan that they'd update the uses/defs/etc. But that turned out to be awkward, do to the order things get cloned if I use the clone_ptr() aproach for blocks/etc (in particular w/ predecessor and successor ptrs). Instead it was easier to just export a fxn which did the important (for us) bits of cf_node_insert()/instr_insert() Rob Clark (7): nir: add nir_var_all enum nir: some small cleanups nir: export update_if_uses() and add_def_uses() nir: add couple array length fields nir: support to clone shaders nir: add shader reference counting nir: add helper macros for running NIR passes src/gallium/drivers/vc4/vc4_program.c | 2 +- src/glsl/Makefile.sources | 1 + src/glsl/nir/glsl_to_nir.cpp | 6 + src/glsl/nir/nir.c | 45 +- src/glsl/nir/nir.h | 102 +++- src/glsl/nir/nir_clone.c | 1012 +++++++++++++++++++++++++++++++ src/glsl/nir/nir_control_flow.c | 6 +- src/glsl/nir/nir_control_flow_private.h | 1 + src/glsl/nir/nir_lower_io.c | 2 +- src/mesa/drivers/dri/i965/brw_nir.c | 127 ++-- src/mesa/program/program.c | 3 +- 11 files changed, 1202 insertions(+), 105 deletions(-) create mode 100644 src/glsl/nir/nir_clone.c -- 2.5.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
