@matthiaskrgr Can you start pingbacking #128790 at least for all of these? |
|
ice since #127407 |
|
@workingjubilee can you add a filter for is:issue is:open label:I-ICE "bpos.to_u32" into the ticket you mentioned? That should find all relevant past an future issues automatically I think. |
|
@matthiaskrgr A filter? How do I do that? |

oh, you mean a link |

…t codepoint boundaries Previously we would try to issue a suggestion for `let x <op>= 1`, i.e. a compound assignment within a `let` binding, to remove the `<op>`. The suggestion code unfortunately incorrectly assumed that the `<op>` is an exactly-1-byte ASCII character, but this assumption is incorrect because we also recover Unicode-confusables like `➖=` as `-=`. In this example, the suggestion code used a `+ BytePos(1)` to calculate the span of the `<op>` codepoint that looks like `-` but the mult-byte Unicode look-alike would cause the suggested removal span to be inside a multi-byte codepoint boundary, triggering a codepoint boundary assertion.

Ensure let stmt compound assignment removal suggestion respect codepoint boundaries Previously we would try to issue a suggestion for `let x <op>= 1`, i.e. a compound assignment within a `let` binding, to remove the `<op>`. The suggestion code unfortunately incorrectly assumed that the `<op>` is an exactly-1-byte ASCII character, but this assumption is incorrect because we also recover Unicode-confusables like `➖=` as `-=`. In this example, the suggestion code used a `+ BytePos(1)` to calculate the span of the `<op>` codepoint that looks like `-` but the mult-byte Unicode look-alike would cause the suggested removal span to be inside a multi-byte codepoint boundary, triggering a codepoint boundary assertion. The fix is to use `SourceMap::start_point(token_span)` which properly accounts for codepoint boundaries. Fixes rust-lang#128845. cc rust-lang#128790 r? `@fmease`
