Split ConstValue into two enums Hello, Issue #59210 appeared abandoned, so I gave it a go. Some further cleanup and refactoring may be mandated. I did not test beyond `x.py check`, since my home computer dies compiling librustc. Fixes #59210

2019-11-11Add hooks for Miri panic unwindingAaron Hill-55/+204
This commits adds in some additional hooks to allow Miri to properly handle panic unwinding. None of this should have any impact on CTFE mode

2019-11-08Rollup merge of #66154 - RalfJung:to_usize, r=oli-obkMazdak Farrokhzad-7/+7
miri: Rename to_{u,i}size to to_machine_{u,i}size Having a function `to_usize` that does not return a (host) usize is somewhat confusing, so let's rename it. r? @oli-obk

2019-11-07Rollup merge of #66147 - RalfJung:no-scalar-ptr, r=oli-obkYuki Okushi-66/+36
Miri: Refactor to_scalar_ptr out of existence `to_scalar_ptr` is somewhat subtle as it just throws away the 2nd component of a `ScalarPair` if there is one -- without any check if this is truly a pointer or so. And indeed we used it wrong on two occasions! So I fixed those two, and then refactored things such that everyone calls `ref_to_mplace` instead (which they did anyway, I just moved up the calls), which is the only place that should interpret a `ScalarPair` as a wide ptr -- and it checks the type first. Thus we can remove `to_scalar_ptr` and `to_meta`. r? @oli-obk

2019-11-06Rollup merge of #65973 - eddyb:caller-location-panic, r=petrochenkovMazdak Farrokhzad-1/+2
caller_location: point to macro invocation sites, like file!/line!, and use in core::panic!. The main change here is to `core::panic!`, trying to fix this remaining regression: https://github.com/rust-lang/rust/pull/65927#issuecomment-547625147 However, in order for `caller_location` to be usable from macros the same way `file!()`/`line!()` are, it needs to have the same behavior (of extracting the macro invocation site `Span` and using that). Arguably we would've had to do this at some point anyway, if we want to use `#[track_caller]` to replace the `file!()`/`line!()` uses from macros, but I'm not sure the RFC mentions this at all. r? @petrochenkov cc @anp @nnethercote
