Previously we did not support anything except "local: *", patch changes that. Actually GNU rules of proccessing wildcards are more complex than that (http://www.airs.com/blog/archives/300): There are 2 iteration for wildcards, at first iteration "*" wildcards are ignored and handled at second iteration. Since we previously decided not to implement such complex rules, I suggest solution that is implemented in this patch. So for "local: *" case nothing changes, but if we have wildcarded locals, they are processed before wildcarded globals. This should fix several FreeBSD ports, one of them is jpeg-turbo-1.5.1 and currently blocks about 5k of ports. Differential revision: https://reviews.llvm.org/D26395 llvm-svn: 286713
