// This test was created in response to an obscure miscompilation bug, only
|
|
// visible with the -O3 flag passed to the cc compiler when trying to obtain
|
|
// a native static library for the sake of foreign function interface. This
|
|
// flag could cause certain integer types to fail to be zero-extended, resulting
|
|
// in type casting errors. After the fix in #97800, this test attempts integer casting
|
|
// while simultaneously interfacing with a C library and using the -O3 flag.
|
|
// See https://github.com/rust-lang/rust/issues/97463

|
|
//@ ignore-cross-compile

|
// Reason: The compiled binary is executed.
