svn commit: r203664 - in projects/ppc64: contrib/gdb/gdb gnu/usr.bin/binutils/libbfd

[Nathan Whitehorn]

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.
