2020-04-04Auto merge of #69718 - arlosi:debughash, r=eddybbors-0/+11
Add hash of source files in debug info LLVM supports placing the hash of source files inside the debug info. This information can be used by a debugger to verify that the source code matches the executable. This change adds support for both hash algorithms supported by LLVM, MD5 and SHA1, controlled by a target option. * DWARF only supports MD5 * LLVM IR supports MD5 and SHA1 (and SHA256 in LLVM 11). * CodeView (.PDB) supports MD5, SHA1, and SHA256. Fixes #68980. Tracking issue: #70401 rustc dev guide PR with further details: https://github.com/rust-lang/rustc-dev-guide/pull/623
2020-04-03Auto merge of #70156 - michaelwoerister:incr-cgus, r=nikomatsakisbors-3/+2
Make the rustc respect the `-C codegen-units` flag in incremental mode. This PR implements (the as of yet unapproved) major change proposal at https://github.com/rust-lang/compiler-team/issues/245. See the description there for background and rationale. The changes are pretty straightforward and should be easy to rebase if the proposal gets accepted at some point. r? @nikomatsakis cc @pnkfelix

They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits.

Small fixes in rustdoc book I read the `rustdoc` book today and noticed some small typos/problems. Mainly: - `# fn foo() {}` was displayed when not needed because fenced block code type was `text` instead of `rust`; - two path separators were missing and some Windows-style separators were not consistent with the rest of them (mainly Linux-style). Here are my proposed fixes. It is my first PR for the rust project. Don't hesitate to tell me if I am doing it wrong or if you need anything else. Have a nice day!

2020-03-13Auto merge of #67502 - Mark-Simulacrum:opt-catch, r=Mark-Simulacrumbors-20/+3
Optimize catch_unwind to match C++ try/catch This refactors the implementation of catching unwinds to allow LLVM to inline the "try" closure directly into the happy path, avoiding indirection. This means that the catch_unwind implementation is (after this PR) zero-cost unless a panic is thrown. https://rust.godbolt.org/z/cZcUSB is an example of the current codegen in a simple case. Notably, the codegen is *exactly the same* if `-Cpanic=abort` is passed, which is clearly not great. This PR, on the other hand, generates the following assembly: ```asm # -Cpanic=unwind: push rbx mov ebx,0x2a call QWORD PTR [rip+0x1c53c] # <happy> mov eax,ebx pop rbx ret mov rdi,rax call QWORD PTR [rip+0x1c537] # cleanup function call call QWORD PTR [rip+0x1c539] # <unfortunate> mov ebx,0xd mov eax,ebx pop rbx ret # -Cpanic=abort: push rax call QWORD PTR [rip+0x20a1] # <happy> mov eax,0x2a pop rcx ret ``` Fixes #64224, and resolves #64222.

Remove spotlight I had a few comments saying that this feature was at best misunderstood or not even used so I decided to organize a poll about on [twitter](https://twitter.com/imperioworld_/status/1232769353503956994). After 87 votes, the result is very clear: it's not useful. Considering the amount of code we have just to run it, I think it's definitely worth it to remove it. r? @kinnison cc @ollie27
