Author: dim Date: Sat Nov 17 22:50:50 2012 New Revision: 243191 URL: http://svnweb.freebsd.org/changeset/base/243191 Log: MFC r242835: Reduce LLVM's default stack alignment for i386 from 16 to 4 bytes, as the FreeBSD ABI requires. This is essentially a revert of upstream llvm commit r126226, and it will be reverted by upstream too.
