[PATCH v3 0/3] MR255: vkd3d-shader: Scan for the maximum temporary register in d3dbc and emit a spirv temp array accordingly.
``` On Margate Sands. I can connect Nothing with nothing. ```
-- v3: vkd3d-shader/d3dbc: Scan for the maximum temporary register index. vkd3d-shader: Record a global temporary count per sm4 shader. vkd3d-shader/dxbc: Remove redundant zero-initialization of the vkd3d_shader_desc structure.

Store it in the shader_desc, and declare temps from that when compiling SPIR-V, instead of parsing dcl_instructions.
As part of this change, we declare a single, global temps array (with Private scope instead of Function) which is as large as the maximum of all dcl_temps instructions. It is not clear to me whether this will improve, hurt, or have no significant effect on the lower-level compiler. An alternative is to still redeclare a new temps array every time (although still with a smaller size). --- libs/vkd3d-shader/spirv.c | 19 ++++++++----------- libs/vkd3d-shader/tpf.c | 2 ++ libs/vkd3d-shader/vkd3d_shader_private.h | 2 ++ 3 files changed, 12 insertions(+), 11 deletions(-)
