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			`extern void foo();`
Preserve public static items across LTO 2015-11-06 03:51:03 -06:00			`extern char FOO_STATIC;`
