SPV_EXT_replicated_composites/GL_EXT_spec_constant_composites #3613

Closed jeffbolznv closed 4 weeks ago

jeffbolznv commented 1 month ago

Opportunistically generate SPV_EXT_replicated_composites instructions when the operands all match and when requested by pragma. Also implement GL_EXT_spec_constant_composites, which allows composite types to be spec constants.
