// When the compiler is performing link time optimization, it will
|
|
// need to copy the original rlib file, set the copy's permissions to read/write,
|
|
// and modify that copy - even if the original
|
|
// file is read-only. This test creates a read-only rlib, and checks that
|
|
// compilation with LTO succeeds.

|
// See https://github.com/rust-lang/rust/pull/17619
