Using this approach you should probably update `hlsl_types_are_equal()` and `hlsl_type_clone()`? I don't remember whether there were other similar helpers.

Or even just check if `profile` starts with `"fx_"`... Sure, not a big deal.

Maybe this belongs to `fx.c`?
Also, I don't know if we have a hard policy, but I prefer commit subjects in verbal form rather than nominal. So something like "Add support for..." rather than "Support for...".
Giovanni Mascellani (@giomasce) commented about libs/vkd3d-shader/vkd3d_shader_main.c:
-void set_u32(struct vkd3d_bytecode_buffer *buffer, size_t offset, uint32_t value) +size_t bytecode_reserve_bytes(struct vkd3d_bytecode_buffer *buffer, size_t size) +{
- size_t offset = bytecode_align(buffer);
- if (buffer->status)
return offset;- if (!vkd3d_array_reserve((void **)&buffer->data, &buffer->capacity, offset + size, 1))
- {
buffer->status = VKD3D_ERROR_OUT_OF_MEMORY;return offset;- }
- memset(buffer->data + offset, 0xcd, size);
I'd rather initialize to zero, unless some kind of development flag is set.

The comment mentions "empty strings", but the code seems to rather treat NULL strings differently.

It's the same thing.

Or even just check if `profile` starts with `"fx_"`... Sure, not a big deal.
Why? There are only 4 possible profiles.

Using this approach you should probably update `hlsl_types_are_equal()` and `hlsl_type_clone()`? I don't remember whether there were other similar helpers.
I think it's fine to have them all as equal. Regarding cloning, there are some other fields that are not copied, not sure if it matters, but I can surely update it.

Mmh, usually by "empty string" I mean `""`, i.e., a non-NULL pointer to a zero byte, which is different from a plain NULL pointer.

In this case it's about "variable" names, which you can't declare as null or "" in sources, but can occasionally omit.

Well, to save a few lines. I see no real gain into checking each individual item of that list instead of just comparing the prefix. However, as I said, no big deal.

Ok. I still find the comment a bit confusing, though.
