Zebediah Figura : vkd3d-shader: Lower shader model 1/2 inter-stage I/O to a flat array.
Module: vkd3d Branch: master Commit: 3f52fda8ade3293390c4586cc835ee957a3d4d88 URL: https://gitlab.winehq.org/wine/vkd3d/-/commit/3f52fda8ade3293390c4586cc835ee... Author: Zebediah Figura <zfigura(a)codeweavers.com> Date: Fri Oct 27 12:44:08 2023 -0500 vkd3d-shader: Lower shader model 1/2 inter-stage I/O to a flat array. An alternative is that we stash the reg_type in the signature, but this seems far simpler for the backend to deal with. --- libs/vkd3d-shader/d3dbc.c | 2 - libs/vkd3d-shader/ir.c | 99 ++++++++++++++++++++++++-------- libs/vkd3d-shader/vkd3d_shader_private.h | 2 + 3 files changed, 76 insertions(+), 27 deletions(-) diff --git a/libs/vkd3d-shader/d3dbc.c b/libs/vkd3d-shader/d3dbc.c index ca6e3b72..ce731634 100644 --- a/libs/vkd3d-shader/d3dbc.c +++ b/libs/vkd3d-shader/d3dbc.c @@ -518,8 +518,6 @@ static struct signature_element *find_signature_element_by_register_index( return NULL;
