In this patch, we add the new instruction attribute "sve_type" and use it to annotate the SVE instructions in aarch64-sve.md and aarch64-sve2.md. This allows us to use instruction attributes to group instructions into dispatch groups for dispatch scheduling. While there had already been fine-grained annotation of scalar and neon instructions (mostly using the "type"-attribute), annotation was missing for SVE instructions. The values of the attribute "sve_type" are comparatively coarse-grained, but fulfill the two criteria we aimed for with regard to dispatch scheduling: - the annotation allows the definition of CPU-specific high-level attributes mapping instructions to dispatch constraints - the annotation is by itself CPU-independent and consistent, i.e. all instructions fulfilling certain criteria are tagged with the corresponding value The patch was bootstrapped and tested on aarch64-linux-gnu, no regression.
