--- Comment #2 from Brian Paul <[email protected]> 2009-09-14 16:43:44 PST --- There's another issue but it's a problem with Wine. The following vertex program is illegal: !!ARBvp1.0 PARAM C[66] = { program.env[0..65] }; ADDRESS A0;PARAM zero = {0.0, 0.0, 0.0, 0.0}; ARL A0.x, zero.x; MOV result.position, C[A0.x + 65]; END The problem is the offset in "A0.x + 65" is too large. >From the GL_ARB_vertex_program specification: """ (26) What limits should be imposed on the constants that can be added to or subtracted from the address register for relative addressing? Negative offsets are sometimes useful for shifting down in an array. RESOLVED: -64 to +63 should be sufficient for the time being. Offset sizes are limited to allow offsets to be baked into device-dependent instruction encodings. """ So 65 is illegal according to the GL spec, but when I tested with NVIDIA's driver, offsets up to 255 work without error.
