Subject: ir_to_mesa: Print shader source and compiled IR under MESA_GLSL=dump.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=455290e4281bf53ce2fe248a2adf5163563c44c8;p=mesa.git

ir_to_mesa: Print shader source and compiled IR under MESA_GLSL=dump.

While the Mesa IR dumping includes some corresponding GLSL IR for
correlating Mesa IR to GLSL IR, it doesn't completely express it.
This printing includes things like variable declarations and control
flow structure that is hard to read otherwise.
