Matthew Lugg dcc5e0e10e std.heap: rework c_allocator ... The main goal here was to avoid allocating padding and header space if `malloc` already guarantees the alignment we need via `max_align_t`. Previously, the compiler was using `std.heap.raw_c_allocator` as its GPA in some cases depending on `std.c.max_align_t`, but that's pretty fragile (it meant we had to encode our alignment requirements into `src/main.zig`!). Perhaps more importantly, that solution is unnecessarily restrictive: since Zig's `Allocator` API passes the `Alignment` not only to `alloc`, but also to `free` etc, we are able to use a different strategy depending on its value. So `c_allocator` can simply compare the requested align to `Alignment.of(std.c.max_align_t)`, and use a raw `malloc` call (no header needed!) if it will guarantee a suitable alignment (which, in practice, will be true the vast majority of the time). So in short, this makes `std.heap.c_allocator` more memory efficient, and probably removes any incentive to use `std.heap.raw_c_allocator`. I also refactored the `c_allocator` implementation while doing this, just to neaten things up a little.		2025-12-05 10:19:26 +00:00
