RADEON_DEBUG="fp" output (14.40 KB, text/plain)

RADEON_DEBUG="fp" output

A small fragment shader produces the following output:
r300: Unknown TGSI/RC opcode: CAL
r300: Unknown TGSI/RC opcode: BGNSUB
r300: Unknown TGSI/RC opcode: ENDSUB
r300 FP: Compiler Error:
r500_fragprog_emit.c::translate_rgb_op(): translate_rgb_op: unknown opcode ILLEGAL OPCODE

Using a dummy shader instead.
If there's an 'unknown opcode' message, please file a bug report and attach this log.

The shader looks like this:
vec3 floatToColor(float x)
	if(x == 1.0)
		return vec3(0, 0, 0);

void main()
	gl_FragColor.rgb = floatToColor(1);

RADEON_DEBUG="fp" output is attached

Fixed with the new GLSL compiler. Closing..
