2020-05-13Be less aggressive with `DroplessArena`/`TypedArena` growth.Nicholas Nethercote-13/+26
`DroplessArena` and `TypedArena` use an aggressive growth strategy: the first chunk is 4 KiB, the second is 8 KiB, and it keeps on doubling indefinitely. DHAT profiles show that sometimes this results in large chunks (e.g. 16-128 MiB) that are barely filled. Although these don't contribute to RSS, they clog up the DHAT profiles. This commit changes things so that the doubling stops at 2 MiB. This is large enough that chunk allocations are still rare (you might get 100s instead of 10s of them) but avoids lots of unused space in the worst case. It gives a slight speed-up to cycle counts in some cases.
2020-05-13Fix the new capacity measurement in arenas.Nicholas Nethercote-2/+2
For the given code paths, the amount of space used in the previous chunk is irrelevant. (This will almost never make a difference to behaviour, but it makes the code clearer.)

2019-07-25Auto merge of #60340 - mgeier:cap-vs-capacity, r=alexcrichtonbors-3/+3
Rename .cap() methods to .capacity() As mentioned in #60316, there are a few `.cap()` methods, which seem out-of-place because such methods are called `.capacity()` in the rest of the code. This PR renames them to `.capacity()` but leaves `RawVec::cap()` in there for backwards compatibility. I didn't try to mark the old version as "deprecated", because I guess this would cause too much noise.
2019-07-07rustc: Remove `dylib` crate type from most rustc cratesAlex Crichton-1/+0
Now that procedural macros no longer link transitively to libsyntax, this shouldn't be needed any more! This commit is an experiment in removing all dynamic libraries from rustc except for librustc_driver itself. Let's see how far we can get with that!
