[Bug gdb/19797] New: Unsupported powerpc bfd arch/machine variants


https://sourceware.org/bugzilla/show_bug.cgi?id=19797

            Bug ID: 19797
           Summary: Unsupported powerpc bfd arch/machine variants
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: palves at redhat dot com
  Target Milestone: ---

BFD/binutils/ld know about a few powerpc machines/variants that GDB does not
know about.

When users try to select one such bfd arch, they get:

 (gdb) set architecture powerpc:EC603e 
 Architecture `powerpc:EC603e' not recognized.
 The target architecture is set automatically (currently i386)
 (gdb) 

Which indicates that loading an elf file for such a machine will probably fail.

The full powerpc bfd arch set is:

 (gdb) set architecture powerpc:<TAB>
 403       EC603e    e5500
 601       MPC8XX    e6500
 603       a35       rs64ii
 604       common    rs64iii
 620       common64  titan
 630       e500      vle
 7400      e500mc    
 750       e500mc64  

The ones that are not handled are:

 powerpc:EC603e
 powerpc:e500mc
 powerpc:e500mc64
 powerpc:vle
 powerpc:titan
 powerpc:e5500
 powerpc:e6500
