rustc: Preserve reachable extern fns with LTO All rust functions are internal implementation details with respect to the ABI exposed by crates, but extern fns are public components of the ABI and shouldn't be stripped. This commit serializes reachable extern fns to metadata, so when LTO is performed all of their symbols are not stripped. Closes #14500 2014-06-06 19:48:46 -05:00			`#[no_mangle]`
Update code to account for extern ABI requirement 2020-09-01 16:28:11 -05:00			`pub extern "C" fn foo() {}`
Preserve public static items across LTO 2015-11-06 03:51:03 -06:00

			`pub static FOO_STATIC: u8 = 0;`
