<pre>The GLSL IR seems questionable too...
: GLSL IR for linked fragment program 3:
(
(declare (location=2 shader_out ) vec4 gl_FragColor)
(declare (temporary ) vec4 gl_FragColor)
(declare (location=0 uniform ) Set@0x22dfe20 u_s)
( function main
(signature void
(parameters
)
(
(declare (temporary ) vec4 vec_ctor)
(assign (w) (var_ref vec_ctor) (constant float (1.000000)) )
(assign (xyz) (var_ref vec_ctor) (expression vec3 * (record_ref
(var_ref u_s) color) (array_ref (record_ref (var_ref u_s) arr) (constant int
(0)) ) ) )
(assign (xyzw) (var_ref gl_FragColor) (var_ref vec_ctor) )
(assign (xyzw) (var_ref gl_FragColor@3) (var_ref gl_FragColor) )
))
)
)
It multiplies directly by the array_ref -- there should be a swizzle or other
vec3 conversion on there, no? Or perhaps you're allowed to have vecN * float
directly in the IR. Not sure.</pre>
