Prepare for LLVM 9 update Main changes: * In preparation for opaque pointer types, the `byval` attribute now takes a type. As such, the argument type needs to be threaded through to the function/callsite attribute application logic. * On ARM the `+fp-only-sp` and `+d16` features have become `-fp64` and `-d32`. I've switched the target definitions to use the new names, but also added bidirectional emulation so either can be used on any LLVM version for backwards compatibility. * The datalayout can now specify function pointer alignment. In particular on ARM `Fi8` is specified, which means that function pointer alignment is independent of function alignment. I've added this to our datalayouts to match LLVM (which is something we check) and strip the fnptr alignment for older LLVM versions. * The fmul/fadd reductions now always respect the accumulator (including for unordered reductions), so we should pass the identity instead of undef. Open issues: * https://reviews.llvm.org/D62106 causes linker errors with ld.bdf due to https://sourceware.org/bugzilla/show_bug.cgi?id=24784. To avoid this I've enabled `RelaxELFRelocations`, which results in a GOTPCRELX relocation for `__tls_get_addr` and avoids the issue. However, this is likely not acceptable because relax relocations are not supported by older linker versions. We may need an LLVM option to keep using PLT for `__tls_get_addr` despite `RtLibUseGOT`. The corresponding llvm-project PR is https://github.com/rust-lang/llvm-project/pull/19. r? @ghost

Fix pretty-printing of `$crate` (take 4) Pretty-print `$crate` as `crate` or `crate_name` in unstructured tokens like `a $crate c` in `foo!(a $crate c)`, but only if those tokens are printed as a part of AST pretty-printing, rather than as a standalone token stream. Fixes https://github.com/rust-lang/rust/issues/62325 Previous iterations - https://github.com/rust-lang/rust/pull/56647, https://github.com/rust-lang/rust/pull/57155, https://github.com/rust-lang/rust/pull/57915.

Target::arch can take more than listed options A list of options in a comment like this is almost guaranteed to become out of date: right now it is missing "riscv32" and "riscv64" and perhaps other architectures as well.
2019-07-10Rollup merge of #62278 - cuviper:iter-partition, r=alexcrichtonMazdak Farrokhzad-0/+138
Add Iterator::partition_in_place() and is_partitioned() `partition_in_place()` swaps `&mut T` items in-place to satisfy the predicate, so all `true` items precede all `false` items. This requires a `DoubleEndedIterator` so we can search from front and back for items that need swapping. `is_partitioned()` checks whether the predicate is already satisfied.

`partition_mut()` swaps `&mut T` items in-place to satisfy the predicate, so all `true` items precede all `false` items. This requires a `DoubleEndedIterator` so we can search from front and back for items that need swapping. `is_partitioned()` checks whether the predicate is already satisfied.

clarify that debug_assert does not completely omits the code TIL that debug_assert is implemented using `if cfg!(debug_assertions)` rather than `#[cfg(debug_assertions)]`. This means one can not use API gated with `#[cfg(debug_assertions)]` in `debug_assert` family of macros.

Regression test for issue 42574. Cc #42574. I'm not going to say this *closes* that issue yet, for two reasons: 1. I am still confused about some aspects of the behavior we are observing that bug 2. The "fix" to the diagnostic relies on full NLL (`#![feature(nll)]`); migration mode still has a subpar diagnostic.

2019-07-09Rollup merge of #62450 - nagisa:reclimit, r=pnkfelixMazdak Farrokhzad-29/+389
Raise the default recursion limit to 128 The previous limit of 64 is being (just) barely hit by genuine code out there, which is causing issues like https://github.com/rust-lang/rust/issues/62059 to rear their end. Ideally, we wouldn’t have such arbitrary limits at all, but while we do, it makes a lot of sense to just raise this limit whenever genuine use-cases end up hitting it. r? @pnkfelix Fixes https://github.com/rust-lang/rust/issues/62059
2019-07-09Rollup merge of #62417 - alexreg:fix-self-in-type-alias, r=pnkfelixMazdak Farrokhzad-24/+61
Fix ICEs when `Self` is used in type aliases I think it is right just to disallow this at resolution stage rather than let typeck produce a cyclic error. This is in line with previous behaviour. There was probably no need at all for the change that introduced this bug in #57428, so I've simply reversed it. Fixes #62263, #62364, #62305. r? @eddyb

Exit arm scopes Due to a bug in the HIR CFG construction, borrows for arm scopes were incorrectly leaking into other arms. This PR also includes some drive-by improvements to `-Zunpretty=hir,identified` that would have been helpful while investigating this. Closes #62107

2019-07-09Auto merge of #62460 - RalfJung:llvm-null, r=eddybbors-5/+12
Handle null from LLVMRustGetSectionName As part of https://github.com/rust-lang/rust/pull/58783 and https://github.com/rust-lang/rust/pull/62103, this incorrect use of a NULL pointer was found in the interface to LLVM. That PR is stuck with some linker issues, but there is no reason the soundness fix should have to wait for that.

2019-07-09Rollup merge of #62403 - SimonSapin:concat, r=alexcrichtonMazdak Farrokhzad-74/+76
Replace SliceConcatExt trait with inherent methods and SliceConcat helper trait Before this change `SliceConcatExt` was an unstable extension trait with stable methods. It was in the libstd prelude, so that its methods could be used on the stable channel. This replaces it with inherent methods, which can be used without any addition to the prelude. Since the methods are stable and very generic (with for example a return type that depends on the types of parameters), an helper trait is still needed. But now that trait does not need to be in scope for the methods to be used. Removing this depedency on the libstd prelude allows the methods to be used in `#![no_std]` crate that use liballoc, which does not have its own implicitly-imported prelude.
