Laytan Laats 7df5be2131 fix wrong out of memory in edge cases, just try allocate from block for one source of truth 2025-02-12 19:09:21 +01:00
Barinzaya 98b3a9eacd Added support for growing in place to some arenas.
This affects `runtime.Arena` and `virtual.Arena`, but not currently
`mem.Arena`. These changes allow the last allocation that has been
made to be resized to a larger size by just extending their
allocation in-place, when there's sufficient room in the memory block to
do so.

Shrinking in place and re-using the rest of the allocation can be
supported using almost the same logic, but would require the memory to
be zeroed. Since this would add a additional cost that isn't currently
present, shrinking has not been changed.

Karl Zylinski 11e586494b Clarify that the arena in base:runtime shouldn't be used for anything but the default temp allocator. This is done by renaming the file in which it lives, and also by improving the comment above Arena :: struct {. This should avoid some confusion where people end up using the Arena in base:runtime because they thought it was the 'default arena'. 2024-06-18 12:48:16 +02:00
