[Mesa-dev] [PATCH 0/2] tgsi: texture type support

[Rob Clark]

From: Rob Clark <robclark at freedesktop.org>

Some drivers (well, at least freedreno, maybe others?) need to know
when compiling the shader whether the texture is float/int/unsigned.
This information is in GLSL IR, and in NIR, but lacking in TGSI.

This was previously worked around in the driver by using a shader
variant.  But that is annoying and stupid.

Rob Clark (2):
  tgsi: add texture-type info to texture instructions
  gallium/ttn: add texture-type support
