$OpenBSD: patch-tools_lld_ELF_SymbolTable_cpp,v 1.1 2017/03/23 08:26:07 ajacoutot Exp $

Work around a problem where linker-generated symbols are not properly
|
|
versioned and end up as local symbols despite being explicitly listed as
|
|
global in the version script. This breaks our brk()/sbrk() implementation.
|
|
|
|
The diff is only a partial solution and unlikely to be accepted as-is
|
|
upstream. We'll keep it as a local diff until a better solution is found.
