Set cfg(test) when rustdoc is running with --test option
Following a [discussion on twitter](https://twitter.com/burntsushi5/status/1117091914199785473), I proposed this change. What do you think about it?
r? @QuietMisdreavus
cc @BurntSushi
Improved error message when type must be bound due to generator.
Fixes#58930.
Keen to get some feedback - is this as minimal as we can get it or is there an existing visitor I could repurpose?
Unfortunately, this didn't have quite the effect I was hoping for.
Locals still appear visible at every point in the function, regardless
of scopes. I suspect all the rewriting of the MIR we do for the
generator transform makes these scopes less useful.
I didn't observe any regressions in behavior, but it's possible that
this change is wrong without additional changes to the MIR.
Implement saturating_abs() and saturating_neg() functions for signed integer types
Similar to wrapping_abs() / wrapping_neg() functions but saturating at the numeric bounds instead of wrapping around. Complements the existing set of functions with saturation mechanics.
cc #59983
It looks like the `OutputType::Metadata` kind in the compiler was
misclassified in #38571 long ago by accident as incompatible with
codegen units and a single output file. This means that if you emit both
a linkable artifact and metadata it silently turns off multiple codegen
units unintentionally!
This commit corrects the situation to ensure that if `--emit metadata`
is used it doesn't implicitly disable multiple codegen units. This will
ensure we don't accidentally regress compiler performance when striving
to implement pipelined compilation!
