[WineHQ Bugzilla]

https://bugs.winehq.org/show_bug.cgi?id=56465

            Bug ID: 56465
           Summary: d3dcompiler fails to compile shader functions that
                    have optional arguments ("E5000: syntax error,
                    unexpected '=', expecting ')'")
           Product: vkd3d
           Version: 1.11
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: hlsl
          Assignee: wine-bugs(a)winehq.org
          Reporter: alexhenrie24(a)gmail.com
      Distribution: ---

Minimal example (compile with `i686-w64-mingw32-cc *.c -ld3dx9_36`):

#include <windows.h>
#include <d3dx9shader.h>
#include <stdio.h>

int main()
{
    static const char src[] = "float4 main(float4 color : COLOR =
float4(0,0,0,0)) : COLOR { return color; }";
    ID3DXBuffer *out = NULL;
    HRESULT res = D3DXCompileShader(src, sizeof(src), NULL, NULL, "main",
"ps_2_0", 0, &out, NULL, NULL);
    printf("res=%x\n", res);
    return res;
}

Output:

0024:err:d3dcompiler:D3DCompile2 Failed to compile shader, vkd3d result -4.
0024:err:d3dcompiler:D3DCompile2 Shader log:
0024:err:d3dcompiler:D3DCompile2     <anonymous>:1:36: E5000: syntax error,
unexpected '=', expecting ')'
0024:err:d3dcompiler:D3DCompile2 
res=80004005

Output after `winetricks d3dcompiler_47`:

res=0

That's going to take a lot of work. Do you have an application that requires
this?

Created attachment 76769
  --> https://bugs.winehq.org/attachment.cgi?id=76769
log + shaders

It seems the Nvidia GeoForms demo (bug 43481) might require this too. I've
attached a log and the dumped shaders (compressed).

This works with vkd3d 1.13, most likely after
49caeee1fd59c6e15ef7eb99f31c3bbbed4dd5e5.

Alex, could you please retry if you have more test cases besides what's in this
bug description?
