Wilson Snyder 3d386f8fa5 Internals: Add VL_DO_DANGLING in some missing places. No functional change intended. 2026-09-23 18:27:40 -04:00
Geza Lore d04647f459 Fix library method argument references (#8252) 
Each VCMethod now carries a signature describing the access required of
the references passed as arguments to the call. 'r' if the argument is
read, 'w' if it is fully assigned so the old value does not matter, 'm'
if it is modified (or only conditionally assigned), with a trailing '+'
repeating the preceding entry for all remaining arguments.  Signatures
are validated at compile time, and V3Broken checks the arguments of
every AstCMethodHard against them.

The incorrect references this found and that are easy to fix are
repaired in this patch. "TODO" marks method that are currently broken or
not yet fit the scheme, these will be fixed in follow up patches.

Also renames SCHED_COMMIT and SCHED_ENQUEUE to NBA_COMMIT and
NBA_ENQUEUE, and remove unused methods.
