[PATCH v4 0/5] MR636: vkd3d-shader/fx: Add initial support for writing buffers descriptions.
-- v4: vkd3d-shader/fx: Do not align structured data section. vkd3d-shader/fx: Add initial support for writing buffers descriptions.
From: Nikolay Sivov nsivov@codeweavers.com
The helper will need to access group annotations later, and these are available for variables.

This is useful for implicit $Globals buffer when writing effects binaries. It should not be written out if there is no global variables, but when there are some, it should appear first in order.

This is useful for implicit $Globals buffer when writing effects binaries. It should not be written out if there is no global variables, but when there are some, it should appear first in order.
What if there are global variables, but they're unused? I.e. should this just be checking "used_size"?
If the answer is no, I think this is still redundant with "size".
Zebediah Figura (@zfigura) commented about libs/vkd3d-shader/vkd3d_shader_main.c:
return offset;}
+size_t bytecode_put_bytes(struct vkd3d_bytecode_buffer *buffer, const void *bytes, size_t size) +{
- return bytecode_put_bytes_internal(buffer, bytes, size, true);
+}
+size_t bytecode_put_bytes_unaligned(struct vkd3d_bytecode_buffer *buffer, const void *bytes, size_t size) +{
- return bytecode_put_bytes_internal(buffer, bytes, size, false);
+}
Couldn't bytecode_put_bytes() just call bytecode_align() and then call bytecode_put_bytes_unaligned()? Then we only need two functions instead of three.

Unused ones are included as well. Yes, it makes sense to use 'size', and actually it's necessary to set offsets anyway.

I see now why additional field was easier - 'size' is set later on, that involves extern_vars which is not populated initially, and that depends on uniform_copy() which, if separated, depends on entry point presence. Still, it's better to use the same field everywhere, I'll see how I can separate this in a way that makes sense. E.g. there is no need to handle function parameters for effects, I don't think it's possible to use them there, and have $Params block written out as a result.
