Alex Crichton	3d6f263b2a	std: Compile libbacktrace with -fvisibility=hidden ... We don't want these symbols exported from the standard library, this is just an internal implementation detail of the standard library currently. Closes #34984	2017-01-26 23:48:08 -08:00
Alex Crichton	a5561ce2b9	rustc: Don't export builtins/panic/alloc syms ... This hides symbols from various unstable and implementation-detail crates of the standard library. Although typically transitive exported `pub extern` functions are exported from cdylibs, these crates aren't necessary as they're all implementation details. Closes #34493	2017-01-26 23:47:39 -08:00
