Hello, The previous series [0], which is already in master, implemented the minimum stuff to get sized types in NIR. This new batch starts the implementation of proper fp64 support in NIR by fixing bit-size calculations everywhere. It also adds support for doubles to glsl_to_nir and adds required opcodes to handle conversions to/from double and double pack/unpack operations.
This will be the foundation for the rest of fp64 work in NIR, which will basically add a bunch of lowering passes to address common hardware limitations and that we will send that in a different series after this. We checked that these patches do not add any piglit regression. This series is available in our Github repo [1], you can use the following bash command to clone it: $ git clone -b nir-bit-size-fixes https://github.com/Igalia/mesa.git Thanks, Sam [0] https://lists.freedesktop.org/archives/mesa-dev/2016-March/109277.html [1] https://github.com/Igalia/mesa/tree/nir-bit-size-fixes Andres Gomez (1): nir/print: Adds support for printing double typed consts Connor Abbott (15): nir/from_ssa: adapt to different bit sizes nir/locals_to_regs: adapt to different bit sizes nir/vars_to_ssa: adapt to different bit sizes nir/lower_vec: adapt to different bit sizes nir/glsl_to_nir: support doubles nir/print: print the bitsize of registers and SSA defs nir: add support for printing double immediates nir: handle doubles in nir_deref_get_const_initializer_load() nir/instr_set: handle 64-bit bit-sizes nir/split_var_copies: handle doubles nir: add support for d2f and f2d nir: add support for (un)pack_double_2x32 nir: don't try to scalarize unpack_double_2x32 nir: add split versions of (un)pack_double_2x32 nir: add a pass for lowering (un)pack_double_2x32 Iago Toral Quiroga (12): nir/clone: clone bit_size in clone_load_const nir/lower_to_source_mods: Handle different bit sizes nir/lower_tex: fix get_zero_or_one() to use sized types nir/lower_tex: fix get_texture_size() to use sized types program/nir: include bit-size information nir/lower_load_const_to_scalar: suppport doubles and multiple bit sizes nir/glsl_to_nir: set the bit-size in the result of evaluate_rvalue nir: fix up bit sizes for undefined alu sources nir/glsl_to_nir: set bit_size on ssbo_load result nir: add d2i, d2u, d2b opcodes nir: add i2d and u2d opcodes nir/lower_to_source_mod: Skip unsafe operations Samuel Iglesias Gonsálvez (1): nir: verify destination bit size when checking algebraic optimizations src/compiler/Makefile.sources | 1 + src/compiler/glsl/Makefile.sources | 1 + src/compiler/nir/Makefile.sources | 1 + src/compiler/nir/glsl_to_nir.cpp | 91 ++++++++++++------ src/compiler/nir/nir.c | 5 + src/compiler/nir/nir.h | 2 + src/compiler/nir/nir_algebraic.py | 11 ++- src/compiler/nir/nir_clone.c | 1 + src/compiler/nir/nir_from_ssa.c | 2 + src/compiler/nir/nir_instr_set.c | 22 ++++- src/compiler/nir/nir_lower_alu_to_scalar.c | 3 + src/compiler/nir/nir_lower_double_packing.c | 109 ++++++++++++++++++++++ src/compiler/nir/nir_lower_load_const_to_scalar.c | 6 +- src/compiler/nir/nir_lower_locals_to_regs.c | 1 + src/compiler/nir/nir_lower_tex.c | 5 +- src/compiler/nir/nir_lower_to_source_mods.c | 27 +++++- src/compiler/nir/nir_lower_vars_to_ssa.c | 3 + src/compiler/nir/nir_lower_vec_to_movs.c | 1 + src/compiler/nir/nir_opcodes.py | 72 ++++++++++++++ src/compiler/nir/nir_print.c | 17 +++- src/compiler/nir/nir_split_var_copies.c | 2 + src/compiler/nir/nir_validate.c | 10 ++ src/mesa/program/prog_to_nir.c | 2 +- 23 files changed, 350 insertions(+), 45 deletions(-) create mode 100644 src/compiler/nir/nir_lower_double_packing.c -- 2.5.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
