does glslang currently support any of these framebuffer_fetch extensions? is there a way to parse built-ins like gl_LastFragData by glslang? thanks.

Sorry for the slow response.

It does not appear these are currently supported, including gl_LastFragData.

I believe it is "possible" for glslang to parse gl_LastFragData. I would be open to accepting a PR which supports this if someone created one.
