History

Nicholas Nethercote fb80c73fb3 Remove `DropArena`. Most arena-allocate types that impl `Drop` get their own `TypedArena`, but a few infrequently used ones share a `DropArena`. This sharing adds complexity but doesn't help performance or memory usage. Perhaps it was more effective in the past prior to some other improvements to arenas. This commit removes `DropArena` and the sharing of arenas via the `few` attribute of the `arena_types` macro. This change removes over 100 lines of code and nine uses of `unsafe` (one of which affects the parallel compiler) and makes the remaining code easier to read.	2021-11-15 18:33:43 +11:00

Nicholas Nethercote fb80c73fb3 Remove DropArena.

Most arena-allocate types that impl `Drop` get their own `TypedArena`, but a
few infrequently used ones share a `DropArena`. This sharing adds complexity
but doesn't help performance or memory usage. Perhaps it was more effective in
the past prior to some other improvements to arenas.

This commit removes `DropArena` and the sharing of arenas via the `few`
attribute of the `arena_types` macro. This change removes over 100 lines of
code and nine uses of `unsafe` (one of which affects the parallel compiler) and
makes the remaining code easier to read.
