Investigate if we really need to ship d3dx9
.dll with Windows builds
On Windows, ANGLE's dependency on d3dx9.dll might be non-essential and we might be able to do without that DLL. That would allow us to significantly reduce the Firefox download size. Anyone wanting to investigate this: our copy of ANGLE is under gfx/angle/.
In the latest Firefox 12.0 builds, d3dx9_43.dll is 1.9MB (and D3DCompiler_43.dll, which isn't in question here, is 2.0MB). If I remove it from the .zip version, the reduction in size of the .zip is 850k. YMMV with the installer build. Gerv (on Linux)
Very helpful description of what has to be done here: http://code.google.com/p/angleproject/issues/detail?id=311#c1 Pasting it here: We've currently got the following usage of D3DX: * D3DXCompileShader (Blit.cpp) * should use D3DCompile like Program.cpp does (simple) * D3DXGetShaderConstantTable (Program.cpp) * replace with usage D3D11 reflection API (also part of d3dcompiler_xx.dll) * this is a non-trivial amount of work. * D3DXFloat16To32Array (Context.cpp) * re-implement Float16 to Float32 conversions (medium) * D3DXLoadSurfaceFromSurface (Texture.cpp) * re-implement surface loading for all the cases we currently use (medium)
ANGLE revision 1314 fixes it. So we just need to take advantage of this. This is bug 808785. It's a mentored bug, it wants a taker.
