[Mesa-dev] EXT_gpu_shader4 glsl

[Dave Airlie]

Hi guys,

So I've been noticing there are a number of inconsistencies between
EXT_gpu_shader4 and GLSL1.30, are you planning on implementing
EXT_gpu_shader4?

EXT_gpu_shader4 appears to define "unsigned" and can also use
texture2D to sample from integer samplers.

My main worry is we end up needing GL3.0 entrypoints when we are
missing float texture for example, so we would want to expose
EXT_gpu_shader4 then I suppose,
but then we would want to fix up the GLSL handling for it.

Dave.
