ANGLE generates invalid HLSL code for shader #59

Closed afd closed 7 years ago

afd commented 7 years ago

It appears that ANGLE generated invalid HLSL code for this shader:

https://github.com/mc-imperial/shader-compiler-bugs/blob/master/angle/front-end/vector-issue/example.frag

The following internal error is given:

" Failed to link shader program. C:\fakepath(94,45): error X3000: syntax error: unexpected token ',' C:\fakepath(94,1-53): error X3013: 'dyn_index_write_vec3': no matching 0 parameter function
