Renamed the struct to make it a little clearer that it doesn't just hold one
imports map. (I couldn't bring myself to write it as `ThinLTOImportsExports`
though, mainly since the exports map is literally derived from the imports map
data.) Added some doc to the struct too.
Revised comments to add link to the newer issue that discusses why the exports
are relevant.
Renamed a few of the methods so that the two character difference is more
apparent (because 1. the method name is shorter and, perhaps more importantly,
the changed characters now lie at the beginning of the method name.)
The `FnAbi` now knows if the function is allowed to unwind. If a
function isn't allowed to unwind, we can use a `call` instead of an
`invoke`.
This resolves an issue when calling LLVM intrinsics which cannot unwind
LLVM will generate an error if you attempt to invoke them so we need to
ignore cleanup blocks in codegen and generate a call instead.
Entirely remove `DUMMY_HIR_ID`
Some helpers functions have been introduced to deal with (buggy) cases
where either a `NodeId` or a `DefId` do not have a corresponding `HirId`.
Those cases are tracked in issue #71104.
rustc_target: Refactor target specifications related to Windows and UEFI
- LLD support is improved.
- Code is cleaned up.
- Target specs are organized in a more hierarchical way.
- Possible issues in UWP and UEFI platforms are identified (see FIXMEs).
The code is better read per-commit.
Add lint for float in array comparison
Fixes#4277
changelog:
- Added new handler for expression of index kind (e.g. `arr[i]`). It returns a constant when both array and index are constant, or when the array is constant and all values are equal.
- Trigger float_cmp and float_cmp_const lint when comparing arrays. Allow for comparison when one of the arrays contains only zeros or infinities.
- Added appropriate tests for such cases.
Refactor: Use rustc's `match_def_path`
This replaces our match_def_path implementation with the rustc one.
Note that we can't just use it in all call sites because of the
`&[&str]` / `&[Symbol]` difference in Clippy/rustc.

Don't always run `add_call_guards` pass
It is only needed when `add_retag` runs.
(the pass is run again to split critical edges before codegen, that one is required)
The ioctl(FIONBIO) method of setting a file descriptor to be
non-blocking does not notify the underlying resource in the same way
that fcntl(F_SETFL, O_NONBLOCK) does on illumos and Solaris.
