2019-04-26Update handling of Tuplevarkor-3/+4
2019-04-11Add discr_index to multi-variant layoutsTyler Mandry-0/+4
We relax the assumption that the discriminant is always field 0, in preparations for layouts like generators where this is not going to be the case.

pnkfelix:issue-57038-sidestep-ice-in-fieldplacement-count, r=michaelwoerister Don't call `FieldPlacement::count` when count is too large Sidestep ICE in `FieldPlacement::count` by not calling it when count will not fit in host's usize. (I briefly played with trying to fix this by changing `FieldPlacement::count` to return a `u64`. However, based on how `FieldPlacement` is used, it seems like this would be a largely pointless pursuit... I'm open to counter-arguments, however.) Fix #57038

Cleanup rustc/ty part 2 The second part of cleanups and minor improvements for rustc/ty. - improve allocations - calculate span after a possible early continue - simplify some patterns - mark a comment as FIXME - whitespace fixes The PR is independent from from the first part.

2018-09-29don't elide lifetimes in paths in librustc/Zack M. Davis-7/+7
This seemed like a good way to kick the tires on the elided-lifetimes-in-paths lint (#52069)—seems to work! This was also pretty tedious—it sure would be nice if `cargo fix` worked on this codebase (#53896)!

2018-07-05Store scalar pair bools as i8 in memoryJosh Stone-7/+2
We represent `bool` as `i1` in a `ScalarPair`, unlike other aggregates, to optimize IR for checked operators and the like. With this patch, we still do so when the pair is an immediate value, but we use the `i8` memory type when the value is loaded or stored as an LLVM aggregate. So `(bool, bool)` looks like an `{ i1, i1 }` immediate, but `{ i8, i8 }` in memory. When a pair is a direct function argument, `PassMode::Pair`, it is still passed using the immediate `i1` type, but as a return value it will use the `i8` memory type. Also, `bool`-like` enum tags will now use scalar pairs when possible, where they were previously excluded due to optimization issues.
