// This test is almost identical to `cgu_invalided_via_import`, except that
|
|
// the two versions of `inline_fn` are identical. Neither version of `inlined_fn`
|
|
// ends up with any spans in its LLVM bitecode, so LLVM is able to skip
|
|
// re-building any modules which import 'inlined_fn'
|
|
|
|
// revisions: cfail1 cfail2 cfail3
|
|
// compile-flags: -Z query-dep-graph -O
|
|
// build-pass (FIXME(62277): could be check-pass?)
