This patch fixes vertex processing issue of bug 33770.
The problem comes from the fact that even if the call succeeds,
the game interprets a non null error_messages pointer as an error.
By calling D3DCompile we use a newer version of the compiler which is more
strict and generates the following warning.
- warning X3206: 'dot': implicit truncation of vector type
- warning X3206: implicit truncation of vector type
- warning X3206: 'mul': implicit truncation of vector type
D3DCompileShader does not generate such warnings.
These is confirmed in the DX SDK release note:
New Warning X3206: Implicit Truncation of Vector Type
Beginning in the August 2009 release of the DirectX SDK, the compiler will warn
when an implicit truncation of a vector type occurs.
The warnings cannot be disable so this patch filters out these strings in D3DCompileShader
and reset the error messages pointer if the resulting buffer is empty.
Try 2:
- only filter out lines containing "X3206:" in case d3dcompiler_43 has localization
Try 3:
- use move in place instead of copying the buffer
Try 4:
- filter simplification by Sebastian and remove 'mul' testing left-out in search string
