Add AmberScript back end #6

Open afd opened 3 years ago

It would be useful to be able to generate AmberScript and run the Amber binary instead of ShaderTrap.

This would require:

[x] Having an option to request that SSBOs are homogeneous - i.e., so that they don't mix different data types (all float data, all int data or all uint data)
[ ] Generating the GLSL code in a comment (lines start with #) and have the SPIR-V assembly be used as the actual shader text
[x] Invoking Amber in the right way so that it dumps the relevant SSBOs into files

Clearly generation and reduction should still take place at the GLSL source level.

Added support for Amber with GLSL code with commit https://github.com/AaronGhost/glslsmith/commit/87378adfbec2f088a40f20dd18c1188b94b9ce24.

The config file format has changed to support multiple back-ends. The install script has not been updated yet. Scripts accept a new option to select the host language. For example:

python3 exec_glslsmith.py --host amber

The shadertrap line has been replaced with a executors section in the python config file (see readme).
