2019-11-21Address review commentsMatthew Jasper-2/+1
2019-11-21Track pointers to statics in MIRMatthew Jasper-2/+19
2019-11-21Remove statics from HAIR by lowering them to a pointer constantOliver Scherer-10/+0
2019-11-11Evaluate borrow and struct expressions in `into`Matthew Jasper-90/+111
This fixes some ordering problems around assignment expressions.
2019-11-11Fix soundness issue with index bounds checksMatthew Jasper-51/+252
An expression like `x[1][{ x = y; 2}]` would perform the bounds check for the inner index operation before evaluating the outer index. This would allow out of bounds memory accesses.
2019-11-11Avoid a string comparison in MIR constructionMatthew Jasper-3/+2
2019-10-22Move Place::elem methods and friends to TyCtxtSantiago Pastorino-6/+7
2019-10-22Intern place projectionSantiago Pastorino-13/+18
2019-10-22Pattern match over PlaceRef rather than PlaceSantiago Pastorino-11/+11
This prepares the code base for when projection is interned. Place's projection field is going to be `&List<PlaceElem<'tcx>>` so we won't be able to pattern match against it.

2019-09-29Get the type of a local from `local_decls` in `schedule_drop`Matthew Jasper-3/+0
Passing around a separate type is unnecessary and error-prone.
2019-09-26Rename `Expr.node` to `Expr.kind`varkor-1/+1
For both `ast::Expr` and `hir::Expr`.
2019-09-25Rename `sty` to `kind`varkor-1/+1
2019-09-19avoid generating drops for moved operands of callsNiko Matsakis-0/+3
Currently, after a CALL terminator is created in MIR, we insert DROP statements for all of its operands -- even though they were just moved shortly before! These spurious drops are later removed, but not before causing borrow check errors. This PR series modifies the drop code to track operands that were moved and avoid creating drops for them. Right now, I'm only using this mechanism for calls, but it seems likely it could be used in more places.

`hair::pattern::PatternRange`.
2019-08-10Revert "Simplify MIR generation for logical ops"Andreas Jonson-23/+30
This reverts commit e38e954a0d249f88d0a55504f70d6055e865a931. llvm were not able to optimize the code that well with the simplified mir. Closes: #62993

2019-07-07Only omit StorageLive/Dead for variable that are never initializedMatthew Jasper-25/+40
With `feature(never_type)`, it's not guaranteed that any variable with type `!` isn't ever assigned to.
