-- v10: vkd3d-shader/hlsl: Consider duplicated input semantic types equivalent in SM1. vkd3d-shader/hlsl: Handle possibly different types in input semantic var load. vkd3d-shader/hlsl: Error out when a semantic is used with incompatible types. vkd3d-shader/hlsl: Error out when an output semantic is used more than once. vkd3d-shader/hlsl: Support semantics for array types.

The use of the hlsl_semantic.reported_duplicated_output_next_index field allows reporting multiple overlapping indexes, such as in the following vertex shader:
void main(out float1x3 x : OVERLAP0, out float1x3 y : OVERLAP1) { x = float3(1.0, 2.0, 3.2); y = float3(5.0, 6.0, 5.0); }

While at the same time avoiding reporting overlaps more than once for large arrays:
struct apple { float2 p : sv_position; };
void main(out apple aps[4]) { }

Since in SM1 all vector types use 4 register components, and since SM1 doesn't consider vectors of different dimx incompatible, it is necessary to ensure that the semantic var is created with dimx=4, and to add a cast node. --- libs/vkd3d-shader/hlsl_codegen.c | 22 +++++++++++++++------- 1 file changed, 15 insertions(+), 7 deletions(-)

I split prepend_input_copy() in two functions: prepend_input_copy() and prepend_input_copy_recurse(). Same for append_output_copy().

Yeah, I expressed myself terribly. The point is not really about recursion (which, as you say, is inevitable) as about the control flow structure, which I find a bit hard to scan. In general I don't really like stuff like: ``` int f(...) { if (condition) { lots_of_code(); return ...; }
lots_of_other_code(); return ...; } ```
This is fine when `lots_of_code()` is actually `a_bit_of_code()`, possibly some cleanup or simple case. Then it's clear that the function has a main linear flow with little branches when needed. If instead the function has two main cases, then they should marked more clearly; even better if one of them can be sent to another helper. With the current code it's pretty clear that `prepend_input_copy_recurse()` recurses a few times and then calls `prepend_input_copy()`, and nothign fancier than that.

Ah yes, definitely agreed there.
I'm finding myself increasingly sympathetic to the assertion that no function needs to be vertically (or horizontally) larger than a screen...
