Subject: intel/fs: Add helper to get prog_offset and simd_size
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cb26d9c3119e089a0e0c6b0bf6cfc90193c70326;p=mesa.git

intel/fs: Add helper to get prog_offset and simd_size

This indirection will be used by the variable group size case in a
later change.
