Implement `PROBLEMATIC_CONSTS` generalization
You forgot that `A≈4`, `B≈8`, and `E≈3` and some more constants.
The new `PROBLEMATIC_CONSTS` was generated using this code:
```py
from functools import reduce
def generate_problems(consts: list, letter_digit: dict):
for const in consts:
problem = reduce(lambda string, rep: string.replace(*reversed(rep)), ['%X' % const, *letter_digit.items()])
indexes = [index for index, c in enumerate(problem) if c in letter_digit.keys()]
for i in range(1 << len(indexes)):
yield int(''.join(letter_digit[c] if index in indexes and (i >> indexes.index(index)) & 1 else c for index, c in enumerate(problem)), 0x10)
problems = generate_problems(
[

],
{
'A': '4',
'B': '8',
'E': '3',
}
)
# print(list(problems)) # won't use that to print formatted
from itertools import islice
while len(cur_problems := list(islice(problems, 8))):
print(' ', end='')
print(*cur_problems, sep=', ', end='')
print(',')
```
Make test harness arguments configurable and not `--nocapture`.
* Added config `runnables.extraTestBinaryArgs` to control the args.
* The default is `--show-output` rather than `--nocapture` to prevent unreadable output when 2 or more tests fail or print output at once.
* Renamed variables in `CargoTargetSpec::runnable_args()` for clarity.
Fixes#12737.

> * add `rust-analyzer.runnables.extraTestBinaryArgs` to configure test harness options when running tests; replaces a previously hard-coded `--nocapture` option.
I'm not sure I made the right choices in vocabulary, between “binary”, “executable”, and “runnable”, and “launch” vs. “execute”, so let me know if I missed something to be consistent with in the naming and documentation.

Use raw-dylib for Windows synchronization functions
Fixes#123999 by using the raw-dylib feature to specify the DLL to load the Windows futex functions from (e.g. [`WaitOnAddress`](https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitonaddress)). This avoids reliance on the import library causing that issue.
With apologies to ``@bjorn3,`` as it's currently necessary to revert this for cranelift.
Don't inline integer literals when they overflow - new attempt
Basically #116633 but I implemented the suggested changes.
Fixes#115423. Fixes#116631.
This is my first contribution to this repo so please let me know if I'm supposed to change something :)
Properly handle emojis as literal prefix in macros
Do not accept the following
```rust
macro_rules! lexes {($($_:tt)*) => {}}
lexes!(🐛"foo");
```
Before, invalid emoji identifiers were gated during parsing instead of lexing in all cases, but this didn't account for macro pre-expansion of literal prefixes.
Fix#123696.
Introduce perma-unstable `wasm-c-abi` flag
Now that `wasm-bindgen` v0.2.88 supports the spec-compliant C ABI, the idea is to switch to that in a future version of Rust. In the meantime it would be good to let people test and play around with it.
This PR introduces a new perma-unstable `-Zwasm-c-abi` compiler flag, which switches to the new spec-compliant C ABI when targeting `wasm32-unknown-unknown`.
Alternatively, we could also stabilize this and then deprecate it when we switch. I will leave this to the Rust maintainers to decide.
This is a companion PR to #117918, but they could be merged independently.

Fixes <https://github.com/rust-lang/rust-analyzer/issues/12737>.
For things with easily pre-checked overflow conditions -- shifts and unsigned subtraction -- write then checked methods in such a way that we stop emitting wrapping versions of them.
For example, today <https://rust.godbolt.org/z/qM9YK8Txb> neither
```rust
a.checked_sub(b).unwrap()
```
nor
```rust
a.checked_sub(b).unwrap_unchecked()
```
actually optimizes to `sub nuw`. After this PR they do.
rustdoc-search: single result for items with multiple paths
Part of #15723
Preview: https://notriddle.com/rustdoc-html-demo-9/reexport-dup/std/index.html?search=hashmap
This change uses the same "exact" paths as trait implementors and type alias inlining to track items with multiple reachable paths. This way, if you search for `vec`, you get only the `std` exports of it, and not the one from `alloc`.
It still includes all the items in the search index so that you can search for them by all available paths. For example, try `core::option` and `std::option`, and notice that the results page doesn't show duplicates, but still shows all the items in their respective crates.
