2020-04-19Replace uses of `parse_opt_*` with `parse_*` where possible.Nicholas Nethercote-4/+4
This lets us specify the default at the options declaration point, instead of using `.unwrap(default)` or `None | Some(default)` at some use point far away. It also makes the code more concise.
2020-04-04Auto merge of #69718 - arlosi:debughash, r=eddybbors-26/+30
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-0/+7
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
2020-04-02Add hash of source files in debug infoArlo Siemsen-26/+30
* Adds either an MD5 or SHA1 hash to the debug info. * Adds new unstable option `-Z src-hash-algorithm` to control the hashing algorithm.

2020-03-31Make the rustc respect the `-C codegen-units` flag in incremental mode.Michael Woerister-0/+7
Before this commit `-C codegen-units` would just get silently be ignored if `-C incremental` was specified too. After this commit one can control the number of codegen units generated during incremental compilation. The default is rather high at 256, so most crates won't see a difference unless explicitly opting into a lower count.

2020-03-17Auto merge of #69519 - 12101111:remove-proc-macro-check, r=nagisabors-8/+17
Don't use static crt by default when build proc-macro Don't check value of `crt-static` when build proc-macro crates, since they are always built dynamically. For more information, see https://github.com/rust-lang/cargo/issues/7563#issuecomment-591965320 I hope this will fix issues about compiling `proc_macro` crates on musl host without bring more issues.

2020-03-14rustc_metadata: Remove `rmeta::MacroDef`Vadim Petrochenkov-6/+0
Use `ast::MacroDef` instead. Also remove `Session::imported_macro_spans`, external macros have spans now.
2020-03-10[Miri] Use a session variable instead of checking for an env var alwaysWesley Wiser-0/+24
In CTFE heavy code, checking the env var everytime is inefficient. We can do a lot better by using a `Session` variable instead.

2020-02-05Auto merge of #67429 - mati865:mingw-ultimate-fix, r=alexcrichtonbors-0/+5
windows-gnu: prefer system crt libraries if they are available The origin of the issue is the fact Rust ships mingw-w64 libraries but no headers and prefers own libraries over the system ones. This leads to situation when headers aren't compatible with libraries (mingw-w64 doesn't provide any forward compatibility and AFAIK backwards compatibility is guaranteed only within major release series). It's easier to understand how this PR works when looking at the linker invocation before and with this PR: https://www.diffchecker.com/GEuYFmzo It adds system libraries path before Rust libraries so the linker will prefer them. It has potential issue when system has files with the same names as Rust but that could be avoided by moving Rust shipped mingw-w64 libraries from `lib/rustlib/x86_64-pc-windows-gnu/lib` to say `lib/rustlib/x86_64-pc-windows-gnu/lib/mingw`. Then adding linker paths in this order: Rust libraries, system libraries, Rust shipped mingw-w64 libraries. Fixes #47048 Fixes #49078 Fixes #53454 Fixes #60912

This change adds the x86_64-fuchsia and aarch64-fuchsia LLVM targets to those allowed to invoke -Zsanitizer. Currently, the only overlap between compiler_rt sanitizers supported by both rustc and Fuchsia is ASan.

This reverts commit 3ed3b8bb7b100afecf7d5f52eafbb70fec27f537, reversing changes made to 99b89533d4cdf7682ea4054ad0ee36c351d05df1. We will reland a similar patch at a future date but for now we should get a nightly released in a few hours with the parallel patch, so this should be reverted to make sure that the next nightly is not parallel-enabled.
