2018-05-07Auto merge of #50000 - michaelwoerister:cross-lang-lto, r=alexcrichtonbors-0/+2
Add some groundwork for cross-language LTO. Implements part of #49879: - Adds a `-Z cross-lang-lto` flag to rustc - Makes sure that bitcode is embedded in object files if the flag is set. This should already allow for using cross language LTO for staticlibs (where one has to invoke the linker manually anyway). However, `rustc` will not try to enable LTO for its own linker invocations yet. r? @alexcrichton

2018-05-01Rework force-frame-pointerSimonas Kazlauskas-5/+8
This reworks the force-frame-pointer PR to explicitly only consider the value of the flag if it is provided, and use a target default otherwise. Something that was tried but not kept was renaming the flag to `frame-pointer`, because for flag `frame-pointer=no`, there is no guarante, that LLVM will elide *all* the frame pointers; oposite of what the literal reading of the flag would suggest.
2018-05-01Don't force-enable frame pointers when generating debug infoBjörn Steinbrink-1/+7
We apparently used to generate bad/incomplete debug info causing debuggers not to find symbols of stack allocated variables. This was somehow worked around by having frame pointers. With the current codegen, this seems no longer necessary, so we can remove the code that force-enables frame pointers whenever debug info is requested. Since certain situations, like profiling code profit from having frame pointers, we add a -Cforce-frame-pointers flag to always enable frame pointers. Fixes #11906

2018-04-18Auto merge of #49349 - Zoxc:sync-errors, r=michaelwoeristerbors-7/+7
Make Handler more thread-safe The use of `code_emitted` to suppress extended explanations is not thread safe. I'm not sure why we keep the documentation for errors outside `diagnostics.rs` anyway. It would be better to add a `teach` method to `DiagnosticsBuilder`, so instead of: ``` if self.tcx.sess.teach(&err.get_code().unwrap()) { err.note("..."); } ``` we'd use `err.teach("...")` cc @estebank r? @michaelwoerister

2018-04-17Auto merge of #49836 - nikomatsakis:nll-facts-prep, r=pnkfelixbors-2/+0
prep work for using timely dataflow with NLL Two major changes: **Two-phase borrows are overhauled.** We no longer have two bits per borrow. Instead, we track -- for each borrow -- an (optional) "activation point". Then, for each point P where the borrow is in scope, we check where P falls relative to the activation point. If P is between the reservation point and the activation point, then this is the "reservation" phase of the borrow, else the borrow is considered active. This is simpler and means that the dataflow doesn't have to care about 2-phase at all, at last not yet. **We no longer support using the MIR borrow checker without NLL.** It is going to be increasingly untenable to support lexical mode as we go forward, I think, and also of increasingly little value. This also exposed a few bugs in NLL mode due to increased testing. r? @pnkfelix cc @bobtwinkles
