Message : gen_proc_table: generate `const` tables We never mutate these tables; marking them const allows the loader to shuffle them to a place that makes them readonly after they're init'ed. This isn't intended to be a functional change. Bug: chromium:1084580 Change-Id: If3356f6082945ef1109bf08aab94f7bfb606b951 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2216295 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
