// The generated test harness code contains spans with a dummy location,
|
|
// but a non-dummy SyntaxContext. Previously, the incremental cache was encoding
|
|
// these spans as a full span (with a source file index), instead of skipping
|
|
// the encoding of the location information. If the file gest moved, the hash
|
|
// of the span will be unchanged (since it has a dummy location), so the incr
|
|
// cache would end up try to load a non-existent file using the previously
|
|
// enccoded source file id.
|
|
// This test reproduces the steps that used to trigger this bug, and checks
|
|
// for successful compilation.
|
|
// See https://github.com/rust-lang/rust/issues/83112
