Author: dim Date: Mon Feb 24 21:48:03 2014 New Revision: 262460 URL: http://svnweb.freebsd.org/changeset/base/262460 Log: Pull in r202059 from upstream clang trunk (by Roman Divacky): Implement getDwarfEHStackPointer() and initDwarfEHRegSizeTable() for sparcv9. Enables the libgcc-specific undocumented __builtin_dwarf_sp_column() and __builtin_init_dwarf_reg_size_table() builtins to be compiled for sparc64.
