Author: nwhitehorn Date: Mon Feb 8 15:39:48 2010 New Revision: 203664 URL: http://svn.freebsd.org/changeset/base/203664 Log: Add the rs6000 architecture to binutils and fiddle some target definitions in the GDB tdep. GDB can now successfully debug core files on ppc64, but cannot yet attach to running processes, with this error: warning: Unable to find dynamic linker breakpoint function. Next up is fixing this and making ld believe that our CRT files can handle multiple TOCs, required for linking some large executables like LLVM.
