Remove some wasm/emscripten ignores
I'm planning on landing a few PRs like this that remove ignores that aren't required. This just covers mir-opt and codegen tests.

add rustc_abi debugging attribute
This is the call ABI equivalent of `rustc_layout(debug)`.

This PR fixes `lp64d abi` tests for LoongArch64.

coverage: Tidy up `run-coverage` tests in several small ways
Prior to #114875 (anonymized line numbers), these tests were very sensitive to lines being added/removed, since doing so would change the line numbers in every subsequent line of output. Therefore they ended up with a few small style issues that weren't worth the hassle of fixing.
Now that we can freely rearrange lines without needing to re-bless the entire output, we can tidy up the tests in various trivial ways.

Revert "Use the same DISubprogram for each instance of the same inline function within the caller"
This reverts commit 687bffa49375aa00bacc51f5d9adfb84a9453e17.
Reverting to resolve ICEs reported on nightly.
cc `@dpaoliello`
Fixes #115156
|
|
These changes were made by manually running `rustfmt` on all of the test files,
and then manually undoing all cases where the original formatting appeared to
have been deliberate.
`rustfmt +nightly --config-path=/dev/null --edition=2021 tests/run-coverage*/**/*.rs`
|
|
Prior to #114875, these tests were very sensitive to lines being added/removed,
so the migration to `run-coverage` in #112300 tried hard to avoid disturbing
the existing line numbers. That resulted in some awkward reshuffling when
certain comments/directives needed to be added or moved.
Now that we don't have to worry about preserving line numbers, we can rearrange
those comments into a more conventional layout.
|
|
When one of these tests fails, any compiler warnings will be printed to the
console, which makes it harder to track down the actual reason for failure.
(The outstanding warnings were found by temporarily adding `-Dwarnings` to the
compiler arguments for `RunCoverage` in `src/tools/compiletest/src/runtest.rs`.)
|
|
|
|
On the following example, point at `String` instead of the whole type:
```

Do not convert copies of packed projections to moves.
This code path was introduced in https://github.com/rust-lang/rust/pull/113758
After seeing https://rust-lang.zulipchat.com/#narrow/stream/136281-t-opsem/topic/Packed.20fields.20and.20in-place.20function.20argument.2Freturn.20passing, this may be UB, so should be disallowed.
This should not appear in normally-built MIR, which introduces temporary copies for packed projections.

ignore-debug is only needed when the debug assertions *in the standard library* somehow affect the test. This can happen with inlining but otherwise should be rare. ignore-debug is problematic since PR CI is only run with debug assertions.

Fix CFI: f32 and f64 are encoded incorrectly for cross-language CFI
Fix #115150 by encoding f32 and f64 correctly for cross-language CFI. I missed changing the encoding for f32 and f64 when I introduced the integer normalization option in #105452 as integer normalization does not include floating point. `f32` and `f64` should be always encoded as `f` and `d` since they are both FFI safe when their representation are the same (i.e., IEEE 754) for both the Rust compiler and Clang.

Allow explicit `#[repr(Rust)]`
This is identical to no `repr()` at all. For `Rust, packed` and `Rust, align(x)`, it should be the same as no `Rust` at all (as, afaik, `#[repr(align(16))]` uses the Rust ABI.)
The main use case for this is being able to explicitly say "I want to use the Rust ABI" in very very rare circumstances where the first obvious choice would be the C ABI yet is undesirable, which is already possible with functions as `extern "Rust"`. This would be useful for silencing https://github.com/rust-lang/rust-clippy/pull/11253. It's also more consistent with `extern`.
The lack of this also tripped me up a bit when I was new to Rust, as I expected this to be possible.

Fix ub-int-array test for big-endian platforms
As of commit 7767cbb3b0b332fd0a46e347ea7f68f20109d768, the tests/ui/consts/const-eval/ub-int-array.rs test is failing on big-endian platforms (in particular s390x), as the stderr output contains a hex dump that depends on endianness.
Since this point intentionally verifies the hex dump to check the uninitialized byte markers, I think we should not simply standardize away the hex dump as is done with some of the other tests in this directory.
However, most of the test is already endian-independent. The only exception is one line of hex dump, which can also be made endian-independent by choosing appropriate constants in the source code.
Since the 32bit and 64bit stderr outputs were already (and remain) identical, I've merged them and removed the stderr-per-bitwidth marker.
Fixes (again) https://github.com/rust-lang/rust/issues/105383.
