2020-03-25Rollup merge of #70226 - RalfJung:checked, r=oli-obkDylan DPC-118/+115
use checked casts and arithmetic in Miri engine This is unfortunately pretty annoying because we have to cast back and forth between `u64` and `usize` more often that should be necessary, and that cast is considered fallible. For example, should [this](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/mir/interpret/value/enum.ConstValue.html) really be `usize`? Also, `LayoutDetails` uses `usize` for field indices, but in Miri we use `u64` to be able to also handle array indexing. Maybe methods like `mplace_field` should be suitably generalized to accept both `u64` and `usize`? r? @oli-obk Cc @eddyb

Because it uses `parse_bool` and defaults to true, it is actually impossible to set it to false. And it hasn't been experimental for some time now.

get rid of ConstPropUnsupported; use ZST marker structs instead This gets rid of yet another machine-specific error variant. r? @oli-obk
2020-03-24Rollup merge of #70087 - ecstatic-morse:remove-const-eval-loop-detector, ↵Mazdak Farrokhzad-7/+7
r=RalfJung Remove const eval loop detector Now that there is a configurable instruction limit for CTFE (see #67260), we can replace the loop detector with something much simpler. See #66946 for more discussion about this. Although the instruction limit is nightly-only, the only practical way to reach the default limit uses nightly-only features as well (although CTFE will still execute code using such features inside an array initializer on stable). This will at the very least require a crater run, since it will result in an error wherever the "long running const eval" warning appeared before. We may need to increase the default for `const_eval_limit` to work around this. Resolves #54384 cc #49980 r? @oli-obk cc @RalfJung
