Good morning,
It's taken a long time, but I finally am almost done freeing libsyntax of `vecs_implicitly_copyable` in this pull request, but I'm running into some issues. I've confirmed that all but the last commit (which only disables `vecs_implicitly_copyable` pass the `check` tests. The last commit errors with this message, which makes no sense to me:
```
/Users/erickt/rust/rust/src/libcore/num/f32.rs:35:37: 35:43 error: expected `,` but found `=`
/Users/erickt/rust/rust/src/libcore/num/f32.rs:35 pub pure fn $name($( $arg : $arg_ty ),*) -> $rv {
^~~~~~
```
and this stack trace:

There also a bunch of new warnings that I haven't cleaned up yet: https://gist.github.com/erickt/5048251.
@nikomatsakis thought there might be some scary bug in the parser caused by moving a vector in the parser instead of copying it, which is why I'm filing this pull request before it's ready. Thanks for any help!

As per #2521. Inlining seems to improve performance slightly: Inlined Not Inlined x86: 13.5482 14.4112 x86_64: 17.4712 18.0696 (Average of 5 runs timed with `time`) ```Rust fn foo() -> int { int::from_str(~"28098").unwrap() } fn main() { for 1000000.times { foo(); foo(); foo(); foo(); foo(); } } ``` All run on: Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.35-2~bpo60+1 x86_64 GNU/Linux The MIPS and ARM bits I didn't inline since I'm not as familiar with them and I also can't test them. All green on try.

…tests, r=erikdesjardins,workingjubilee Repair several `riscv64gc-unknown-linux-gnu` codegen tests Together with joshua.zivkovic@codethink.co.uk, we've been starting to explore improving the state of the `riscv64gc-unknown-linux-gnu` target. Additionally, I'm looking to add support for this platform in [Ferrocene](https://github.com/ferrocene/ferrocene) ([Related PR](ferrocene/ferrocene#618)). While running the test suite, we noted several tests were failing. It appears that several of the riscv64gc-unknown-linux-gnu codegen tests have not been updated in some time and seem to have experienced a small amount of bitrot. After speaking with `@workingjubilee` (as I have little expertise in LLVM codegen) I believe these changes to be correct. ### `tests/codegen/riscv-abi/call-llvm-intrinsics.rs` I believe this change does not alter what the test is testing and is harmless. ### `tests/codegen/riscv-abi/riscv64-lp64d-abi.rs` The changes largely mirrors those from loongarch64: https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L15 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L153-L155 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L259-L261 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L263-L267 ### `tests/codegen/riscv-abi/riscv64-lp64f-lp64d-abi.rs` The changes largely mirror that from loongarch64 or llvm: https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L26 https://github.com/rust-lang/llvm-project/blob/5399a24c66cb6164cf32280e7d300488c90d5765/clang/test/CodeGen/RISCV/riscv64-abi.c#L612-L617 ### `tests/ui/debuginfo/debuginfo-emit-llvm-ir-and-split-debuginfo.rs` The test is ignored since `-Csplit-debuginfo=unpacked` is not supported on this platform. Context can be found in #120518. ## Reproducing the failures Using a `config.toml` with the following: ```toml # ... target = [ # ...

…i-obk Tell users not to file a bug when using internal library features Actually fixes #97501. I don't think we should suppress the suggestion to add `#![feature(..)]`, though I guess I could be convinced otherwise. r? `@Nilstrieb` cc `@RalfJung` Didn't add a test b/c I don't think we test this for lang features either, but I can confirm it does work. ``` warning: the feature `core_intrinsics` is internal to the compiler or standard library --> /home/michael/test.rs:1:12 | 1 |

Optimize `Box::default` and `Arc::default` to construct more types in place
Both the `Arc` and `Box` `Default` impls currently call `T::default()` before allocating, and then moving the resulting `T` into the allocation.
Most `Default` impls are trivial, which should in theory allow
LLVM to construct `T: Default` directly in the `Box` allocation when calling
`<Box<T>>::default()`.
However, the allocation may fail, which necessitates calling `T`'s destructor if it has one.
If the destructor is non-trivial, then LLVM has a hard time proving that it's
sound to elide, which makes it construct `T` on the stack first, and then copy it into the allocation.
Change both of these impls to allocate first, and then call `T::default` into the uninitialized allocation, so that LLVM doesn't have to prove that it's sound to elide the destructor/initial stack copy.
For example, given the following Rust code:
```rust
#[derive(Default, Clone)]
struct Foo {
x: Vec<u8>,
z: String,
y: Vec<u8>,
}
#[no_mangle]
pub fn src() -> Box<Foo> {
Box::default()
}
```

shave 150ms off bootstrap This starts `git` commands inside `GitInfo`and the submodule updates in parallel. Git should already perform internal locking in cases where it needs to serialize a modification. ``` OLD Benchmark #1: ./x check core Time (mean ± σ): 608.7 ms ± 4.4 ms [User: 368.3 ms, System: 455.1 ms] Range (min … max): 602.3 ms … 618.8 ms 10 runs NEW Benchmark #1: ./x check core Time (mean ± σ): 462.8 ms ± 2.6 ms [User: 350.2 ms, System: 485.1 ms] Range (min … max): 457.5 ms … 465.6 ms 10 runs ``` This should help with the rust-analyzer setup which issues many individual `./x check` calls. There's more that could be done but these were the lowest-hanging fruits that I saw.

we get these declarations ``` ; opt level 0 declare x86_intrcc void @page_fault_handler(ptr byval([8 x i8]) align 8, i64) unnamed_addr #1 ; opt level > 0 declare x86_intrcc void @page_fault_handler(ptr noalias nocapture noundef byval([8 x i8]) align 8 dereferenceable(8), i64 noundef) unnamed_addr #1 ``` The space after `i64` in the original regex made the regex not match for opt level 0. Removing the space fixes the issue. ``` declare x86_intrcc void @page_fault_handler(ptr {{.*}}, i64 {{.*}}){{.*}}#[[ATTRS:[0-9]+]] ```

The IL module doesn't take a session variable, so its logging and session-state
actions are limited and/or global. Fix this.
