2020-04-29Store LLVM bitcode in object files, not compressedAlex Crichton-16/+2
This commit is an attempted resurrection of #70458 where LLVM bitcode emitted by rustc into rlibs is stored into object file sections rather than in a separate file. The main rationale for doing this is that when rustc emits bitcode it will no longer use a custom compression scheme which makes it both easier to interoperate with existing tools and also cuts down on compile time since this compression isn't happening. The blocker for this in #70458 turned out to be that native linkers didn't handle the new sections well, causing the sections to either trigger bugs in the linker or actually end up in the final linked artifact. This commit attempts to address these issues by ensuring that native linkers ignore the new sections by inserting custom flags with module-level inline assembly. Note that this does not currently change the API of the compiler at all. The pre-existing `-C bitcode-in-rlib` flag is co-opted to indicate whether the bitcode should be present in the object file or not. Finally, note that an important consequence of this commit, which is also one of its primary purposes, is to enable rustc's `-Clto` bitcode loading to load rlibs produced with `-Clinker-plugin-lto`. The goal here is that when you're building with LTO Cargo will tell rustc to skip codegen of all intermediate crates and only generate LLVM IR. Today rustc will generate both object code and LLVM IR, but the object code is later simply thrown away, wastefully.

2019-09-23rustc: Convert `dependency_formats` to a queryAlex Crichton-0/+2
This commit converts a field of `Session`, `dependency_formats`, into a query of `TyCtxt`. This information then also needed to be threaded through to other remaining portions of the linker, but it's relatively straightforward. The only change here is that instead of `HashMap<CrateType, T>` the data structure changed to `Vec<(CrateType, T)>` to make it easier to deal with in queries.

Implement another internal lints cc #49509 This adds ~~two~~ one internal lint~~s~~: 1. LINT_PASS_IMPL_WITHOUT_MACRO: Make sure, that the `{declare,impl}_lint_pass` macro is used to implement lint passes. cc #59669 2. ~~USAGE_OF_TYCTXT_AND_SPAN_ARGS: item 2 on the list in #49509~~ ~~With 2. I wasn't sure, if this lint should be applied everywhere. That means a careful review of 0955835 would be great. Also 73fb9b4 allows this lint on some functions. Should I also apply this lint there?~~ TODO (not directly relevant for review): - [ ] https://github.com/rust-lang/rust/pull/59316#discussion_r280186517 (not sure yet, if this works or how to query for `rustc_private`, since it's not in [`Features`](https://doc.rust-lang.org/nightly/nightly-rustc/syntax/feature_gate/struct.Features.html) :thinking: cc @eddyb) - [x] https://github.com/rust-lang/rust/pull/61735#discussion_r292389870 - [x] Check explicitly for the `{declare,impl}_lint_pass!` macros r? @oli-obk

2019-02-26rustc: Update LLVM, remove dead wasm codeAlex Crichton-1/+0
This commit updates the LLVM branch to the rebased version of the upstream release/8.x branch. This includes a wasm patch which means that the `rewrite_imports` pass in rustc is no longer needed (yay!) and we can instead rely on `wasm-import-module`, an attribute we're already emitting, to take care of all the work.
