fix various typos in doc comments
2018-11-15Rollup merge of #55785 - stjepang:unsized-drop-forget, r=alexcrichtonPietro Albini-1/+1
Add mem::forget_unsized() for forgetting unsized values ~~Allows passing values of `T: ?Sized` types to `mem::drop` and `mem::forget`.~~ Adds `mem::forget_unsized()` that accepts `T: ?Sized`. I had to revert the PR that removed the `forget` intrinsic and replaced it with `ManuallyDrop`: https://github.com/rust-lang/rust/pull/40559 We can't use `ManuallyDrop::new()` here because it needs `T: Sized` and we don't have support for unsized return values yet (will we ever?). r? @eddyb

2018-11-12Auto merge of #55701 - tromey:ice-fix, r=matthewjasperbors-4/+4
Fix emission of niche-filling discriminant values Bug #55606 points out a regression introduced by #54004; namely that an assertion can erroneously fire when a niche-filling discriminant value is emitted. This fixes the bug by removing the assertion, and furthermore by arranging for the discriminant value to be masked according to the size of the niche. This makes handling the discriminant a bit simpler for debuggers. The test case is from Jonathan Turner. Closes #55606

2018-11-11Auto merge of #54993 - TimNN:pda-tdl, r=eddybbors-3/+13
Support for the program data address space option of LLVM's Target Datalayout This was introduced recently (specifically, for AVR, cc @dylanmckay). (I came up with this when attempting to run [avr-rust](https://github.com/avr-rust/rust) rebased on the latest [rust-lang](https://github.com/rust-lang/rust) commits. If this requires a different design, some additional discussions, or is not something to pursue right now, I'd be happy to close this PR). Note that this somewhat overlaps with @DiamondLovesYou's #51576, I think, although the implementation here is significantly simpler: Since the address space applies to _all_ program data, we can just check the pointee's type whenever we create an LLVM pointer type. If it is a function we use the program data address space; if not we use the default address space. cc @eddyb, who has been reviewing #51576 Ref: https://llvm.org/docs/LangRef.html#data-layout
2018-11-10Auto merge of #54864 - ljedrz:cleanup_codegen_llvm_back, r=Mark-Simulacrumbors-139/+110
Cleanup codegen_llvm/back - improve allocations - use `Cow<'static, str>` where applicable - use `to_owned` instead of `to_string` with string literals - remove a redundant `continue` - possible minor speedup in logic - use `mem::replace` instead of `swap` where more concise - remove `'static` from consts - improve common patterns - remove explicit `return`s - whitespace & formatting fixes
2018-11-10Auto merge of #55650 - nikic:funnel-shift, r=nagisabors-5/+45
Implement rotate using funnel shift on LLVM >= 7 Implement the rotate_left and rotate_right operations using llvm.fshl and llvm.fshr if they are available (LLVM >= 7). Originally I wanted to expose the funnel_shift_left and funnel_shift_right intrinsics and implement rotate_left and rotate_right on top of them. However, emulation of funnel shifts requires emitting a conditional to check for zero shift amount, which is not necessary for rotates. I was uncomfortable doing that here, as I don't want to rely on LLVM to optimize away that conditional (and for variable rotates, I'm not sure it can). We should revisit that question when we raise our minimum version requirement to LLVM 7 and don't need emulation code anymore. Fixes #52457.
