[Mesa-dev] [PATCH] glsl: split out libstandalone

Rob Clark robdclark at gmail.com
Tue May 24 23:39:01 UTC 2016


From: Rob Clark <robclark at freedesktop.org>

Split standalone glsl_compiler into a libstandalone.la and a thin
main.cpp.  This way drivers can re-use the glsl standalone frontend in
their own standalone compilers.
