From 4125211e9c46a3b6f3eb82ded7a57a1a07e0fe02 Mon Sep 17 00:00:00 2001 From: Karol Herbst Date: Thu, 19 Jul 2018 13:04:43 +0200 Subject: [PATCH] nir: add legal bit_sizes to intrinsics With OpenCL some system values match the address bits, but in GLSL we also have some system values being 64 bit like subgroup masks. With this it is possible to adjust the builder functions so that depending on the bit_sizes the correct bit_size is used or an additional argument is added in case of multiple possible values. v2: validate dest bit_size v3: generate hex values in python code remove useless imports rename and move bit_sizes v4: add 1 to legal bit_sizes for front_face Signed-off-by: Karol Herbst Reviewed-by: Jason Ekstrand Reviewed-by: Bas Nieuwenhuizen --- src/compiler/nir/nir.h | 3 +++ src/compiler/nir/nir_intrinsics.py | 29 ++++++++++++++++------------ src/compiler/nir/nir_intrinsics_c.py | 5 ++++- src/compiler/nir/nir_validate.c | 6 ++++++ 4 files changed, 30 insertions(+), 13 deletions(-) diff --git a/src/compiler/nir/nir.h b/src/compiler/nir/nir.h index 3e360432051..b805e290094 100644 --- a/src/compiler/nir/nir.h +++ b/src/compiler/nir/nir.h @@ -1313,6 +1313,9 @@ typedef struct { */ unsigned dest_components; + /** bitfield of legal bit sizes */ + unsigned dest_bit_sizes; + /** the number of constant indices used by the intrinsic */ unsigned num_indices; diff --git a/src/compiler/nir/nir_intrinsics.py b/src/compiler/nir/nir_intrinsics.py index 2d89f8861ae..a5cc3f7401c 100644 --- a/src/compiler/nir/nir_intrinsics.py +++ b/src/compiler/nir/nir_intrinsics.py @@ -32,7 +32,7 @@ class Intrinsic(object): NOTE: this must be kept in sync with nir_intrinsic_info.
