Alex Crichton 7c58ab671f rustc: Tweak visibility of some lang items ... This commit tweaks the linker-level visibility of some lang items that rustc uses and defines. Notably this means that `#[panic_implementation]` and `#[alloc_error_handler]` functions are never marked as `internal`. It's up to the linker to eliminate these, not rustc. Additionally `#[global_allocator]` generated symbols are no longer forced to `Default` visibility (fully exported), but rather they're relaxed to `Hidden` visibility). This symbols are *not* needed across DLL boundaries, only as a local implementation detail of the compiler-injected allocator symbols, so `Hidden` should suffice. Closes #51342 Closes #52795		2018-08-07 08:42:38 -07:00
