| Here, glslang proper means core GLSL parsing, HLSL parsing, and SPIR-V code |
| generation. Glslang proper requires use of two licenses, one that covers |
| non-preprocessing and an additional one that covers preprocessing. |
| |
| Bison was removed long ago. You can build glslang from the source grammar, |
| using tools of your choice, without using bison or any bison files. |
| |
| Other parts, outside of glslang proper, include: |
| |
| - gl_types.h, only needed for OpenGL-like reflection, and can be left out of |
| a parse and codegen project. See it for its license. |
| |
| - update_glslang_sources.py, which is not part of the project proper and does |
| not need to be used. |
| |
| - the SPIR-V "remapper", which is optional, but has the same license as |
| glslang proper |
| |
| - Google tests and SPIR-V tools, and anything in the external subdirectory |
| are external and optional; see them for their respective licenses. |
