We're not quite ready to ship parallel compilers by default, but the alt builders are not used too much (in theory), so we believe that shipping a possibly-broken compiler there is not too problematic.
This changes the default parallelism for parallel compilers to one, instead of the previous default, which was "num cpus". This is likely not an optimal default long-term, but it is a good default for testing whether parallel compilers are not a significant regression over a sequential compiler. Notably, this in theory makes a parallel-enabled compiler behave exactly like a sequential compiler with respect to the jobserver.
…xcrichton Make all alt builders produce parallel-enabled compilers We're not quite ready to ship parallel compilers by default, but the alt builders are not used too much (in theory), so we believe that shipping a possibly-broken compiler there is not too problematic. r? @nikomatsakis
BTreeSet intersection, is_subset & difference optimizations ...based on the range of values contained; in particular, a massive improvement when these ranges are disjoint (or merely touching), like in the neg-vs-pos benchmarks already in liballoc. Inspired by rust-lang#64383 but none of the ideas there worked out. I introduced another variant in IntersectionInner and in DifferenceInner, because I couldn't find a way to initialize these iterators as empty if there's no empty set around. Also, reduced the size of "large" sets in test cases - if Miri can't handle it, it was needlessly slowing down everyone.
…i-refactor, r=wesleywiser SelfProfiler API refactoring and part one of event review This PR refactors the `SelfProfiler` a little bit so that most profiling methods are RAII-based. The codegen backend code already had something similar, this refactoring pulls this functionality up into `SelfProfiler` itself, for general use. The second commit of this PR is a review and update of the existing events we are already recording. Names have been made more consistent. CGU names have been removed from event names. They will be added back in when function parameter recording is implemented. There is still some work to be done for adding new events, especially around trait resolution and the incremental system. r? @wesleywiser
syntax: cleanup param, method, and misc parsing Do some misc cleanup of the parser: - Method and parameter parsing is refactored. - A parser for `const | mut` is introduced that rust-lang#64588 can reuse. - Some other misc parsing. Next up in a different PR: - ~Implementing rust-lang#64252 -- maybe some other time... - Heavily restructuring up `item.rs` which is a mess (hopefully, no promises ^^). r? @petrochenkov

Either the Alt PR or Cargo was the cause of the failure I think. |
From the logs, I think it was Cargo. |
