Geza Lore 849cc5aeca Internals: Move wrapTop before V3Coverage (#8291) 2026-09-06 17:34:40 -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.

Geza Lore 566f4e6efc Internals: Add new VL_RESTORER flavours (#7866) 
Restrict VL_RESTORER to be usable only with trivially copyable types.
Introduce VL_RESTORER_COPY and VL_RESTORER_CLEAR, which are more
efficient versions usable for non trivially copyable types.

VL_RESTORER_COPY semantically behaves the same as VL_RESTORER, but only
does one copy at initialization, and on scope exit restores via a move.

VL_RESTORER_CLEAR swaps the variable with an new one constructed via
the no-args constructor (e.g. empty collection), which does not require
any copying at any point.

Static assertions enforce picking one of the new flavours when copying
might be expensive.
