2019-08-07Rollup merge of #63034 - tmandry:reduce-generator-size-regressions, r=cramertjMazdak Farrokhzad-0/+17
Fix generator size regressions due to optimization I tested the generator optimizations in #60187 and #61922 on the Fuchsia build, and noticed that some small generators (about 8% of the async fns in our build) increased in size slightly. This is because in #60187 we split the fields into two groups, a "prefix" non-overlap region and an overlap region, and lay them out separately. This can introduce unnecessary padding bytes between the two groups. In every single case in the Fuchsia build, it was due to there being only a single variant being used in the overlap region. This means that we aren't doing any overlapping, period. So it's better to combine the two regions into one and lay out all the fields at once, which is what this change does. r? @cramertj cc @eddyb @Zoxc

Turn `#[global_allocator]` into a regular attribute macro It was a 99% macro with exception of some diagnostic details. As a result of the change, `#[global_allocator]` now works in nested modules and even in nameless blocks.

2019-07-24syntax_ext: Improve and simplify code generated by `#[global_allocator]`Vadim Petrochenkov-4/+6
Instead of ``` mod allocator_abi { /* methods */ } ``` we now generate ``` const _: () = { /* methods */ } ``` and use `std_path` for paths referring to standard library entities. This way we no longer need to generate `use` and `extern crate` imports, and `#[global_allocator]` starts working inside unnamed blocks.

Normalize type parameters in create_mono_items_for_default_impls. Fix for https://github.com/rust-lang/rust/issues/58375. I've added a test in `src/tests/run-pass` to reproduce the bug, not sure that's the best place for it. See https://github.com/rust-lang/rust/issues/58375#issuecomment-509156977 for more context.

rustc_codegen_ssa: fix range check in codegen_get_discr. Fixes #61696, see https://github.com/rust-lang/rust/issues/61696#issuecomment-505473018 for more details. In short, I had wanted to use `x - a <= b - a` to check whether `x` is in `a..=b` (as it's 1 comparison instead of 2 *and* `b - a` is guaranteed to fit in the same data type, while `b` itself might not), but I ended up with `x - a + c <= b - a + c` instead, because `x - a + c` was the final value needed. That latter comparison is equivalent to checking that `x` is in `(a - c)..=b`, i.e. it also includes `(a - c)..a`, not just `a..=b`, so if `c` is not `0`, it will cause false positives. This presented itself as the non-niche ("dataful") variant sometimes being treated like a niche variant, in the presence of uninhabited variants (which made `c`, aka the index of the first niche variant, arbitrarily large). r? @nagisa, @rkruppe or @oli-obk

ohadravid:test-generic-with-default-assiociated-type-re-rebalance-coherence, r=nikomatsakis Coherence test when a generic type param has a default value from an associated type A followup on #61400. Before `re_rebalance_coherence`, this fails to compile (even though it should be accepted). `re_rebalance_coherence` had no direct test for this, and I wanted to (a) make sure it doesn't regress in the future and (b) get it on record that this is actually the intended behavior.

2019-07-05Rollup merge of #62380 - eddyb:x64-sysv-regs, r=nagisaMazdak Farrokhzad-0/+82
rustc_target: avoid negative register counts in the SysV x86_64 ABI. Because `needed_{int,sse}` and `{int,sse}_regs` were only used with integer literals, they were inferred to `i32` and `{int,sse}_regs` could therefore be negative. There was a check which prevented that, but *only* for aggregate arguments, not scalars. Fixes #62350. r? @nagisa or @rkruppe

Create async version of the dynamic-drop test Some of the tests in dynamic-drop have been cut: * The tests that are just simpler versions of other tests - these tests are already fairly slow due to all of the unwinding and async functions have more control flow paths than normal functions. * The union test - it's for an unstable feature that has an RFC to remove it. * The generator test - there aren't async generators yet. * The tests that show values being leaked - these can be added once the issue is fixed. r? @Centril cc #62121 @cramertj
