2020-05-30Make TLS accesses explicit in MIROliver Scherer-0/+8
2020-05-06Define UB in float-to-int casts to saturateMark Rousskov-1/+1
- Round to zero, and representable values cast directly. - `NaN` goes to 0 - Values beyond the limits of the type are saturated to the "nearest value" (essentially rounding to zero, in some sense) in the integral type, so e.g. `f32::INFINITY` would go to `{u,i}N::MAX.`

2019-12-20Rollup merge of #64588 - matthewjasper:mir-address-of, r=oli-obkMazdak Farrokhzad-20/+38
Add a raw "address of" operator * Parse and feature gate `&raw [const | mut] expr` (feature gate name is `raw_address_of`) * Add `mir::Rvalue::AddressOf` * Use the new `Rvalue` for: * the new syntax * reference to pointer casts * drop shims for slices and arrays * Stop using `mir::Rvalue::Cast` with a reference as the operand * Correctly evaluate `mir::Rvalue::{Ref, AddressOf}` in constant propagation cc @Centril @RalfJung @oli-obk @eddyb cc #64490
2019-12-18Add Rvalue::AddressOf to MIRMatthew Jasper-20/+38
This operator creates a raw pointer to a Place directly, without first creating a reference. See RFC #2582 for motivation. The Rvalue is currently unused.
2019-12-15Remove now-redundant range check on u128 -> f32 castsRobin Kruppe-36/+7
This code was added to avoid UB in LLVM 6 and earlier, but we no longer support those LLVM versions. Since https://reviews.llvm.org/D47807 (released in LLVM 7), uitofp does exactly what we need. Closes #51872

2019-10-25Don't cast directly from `&[T; N]` to `*const T`Matthew Jasper-0/+1
Instead coerce to `*const [T; N]` and then cast.
2019-10-22Pattern match over PlaceRef rather than PlaceSantiago Pastorino-4/+1
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.

2019-09-14Rollup merge of #64435 - eddyb:arguments-against-arg, r=rkruppeMazdak Farrokhzad-1/+1
codegen: use "_N" (like for other locals) instead of "argN", for argument names. Based on #64408 (second commit is new), fixing something I mentioned in #64408 (which turned to be an immediate blocker for unifying relevant codepaths). Closes #64408 (by containing it). r? @rkruppe
2019-09-12codegen: be more explicit about setting giving names to allocas.Eduard-Mihai Burtescu-1/+1

2019-08-29`new_sized` is mostly used without alignDante-Broggi-1/+1
so rename it `new_sized_aligned`. 6/11 use `align` = `layout.align.abi`. `from_const_alloc` uses `alloc.align`, but that is `assert_eq!` to `layout.align.abi`. only 4/11 use something interesting for `align`.
