Patch from Will Schmidt <willschm@us.ibm.com>:jimb-ppc64-linux-20030509-branchcvs/jimb-ppc64-linux-20030509-branch

These changes enable support of PPC64 architecture.
* config/powerpc/ppc64linux.mh: New file.
* config/powerpc/ppc64linux.mt: New file.
* config/powerpc/tm-ppc64linux.h: New file.
* ppc64-linux-tdep.c: New file.
* configure.host: Add clause for powerpc64-*-linux*
* configure.tgt: Add clause for powerpc64-*-linux*
* elfread.c (record_minimal_symbol_and_info): If
DROP_TEXT_NAME_PREFIX_CHAR is #defined, then drop a leading
instance of that char from the names of text symbols.
(elf_symtab_read): If SKIP_DATA_IN_OPD is #defined, ignore data
symbols in the .opd section.
* ppc-linux-nat.c (PTRACE_XFER_TYPE): Change the default for this
to 'long'.
(PPC_PTRACE_POKEUSR_3264, PPC_PTRACE_PEEKUSR_3264,
PPC_PTRACE_POKEDATA_3264, PPC_PTRACE_PEEKDATA_3264): Provide
default definitions for these.
(ARCH64): New macro.
(ppc_wordsize_pid): New function.
(kernel_u_size): Handle 64-bit case.
(ppc_register_u_addr): Same.
(fetch_register): Use the *_3264 requests when
debugging a 64-bit process from a 32-bit GDB.
(store_register): Same.
(GDB_MAX_ALLOCA, child_xfer_memory, udot_info): Copied from
infptrace.c.
(_initialize_ppc_linux_nat): New function, to register our copy of
the udot_info command.
* ppc-linux-tdep.c (TDEP): New macro.
(ppc64_linux_svr4_fetch_link_map_offsets): New function.
(read_memory_addr): Copied from rs6000-tdep.c.
(ppc64_linux_convert_from_func_ptr_addr): New function.
* rs6000-tdep.c (skip_prologue): Recognize more instructions for
saving the 'lr' and 'cr' registers; don't just pre-emptively mask
in the 'st' opcode as soon as we see an 'mflr' or 'mfcr' opcode.
Recognize more instructions for updating the stack pointer, and
loading the TOC pointer.
(registers_powerpc64, registers_a35): New register tables.
(rs6000_gdbarch_init): Register the 64-bit solib functions.
* solib-svr4.c (solib_break_names): If SOLIB_BREAK_NAME is
#defined, include an entry for it.
(enable_break): Call CONVERT_FROM_FUNC_PTR_ADDR when trying to
guess the linker's base address.

-
-                New Features and Enhancements
-                =============================
-
-Display of the target program output.  Perhaps use the XTerm hack created
-by Tom.
-
---
-
-Support for inserting breakpoints at arbitrary locations, perhaps adding an
-entry widget to the breakpoints window.
-
---
-
-Support for hardware breakpoints and watchpoints (will need fixes in gdb).
-
---
-
-"Disassembly from Memory" Window. Perhaps as a pane in place of the source
-code one.
-
---
-
-Register Window capable of handling large number of registers, typed
-registers, registers organized in groups that can be shown/hidden and
-that provide for better screen organization.
-
---
-
-Per-project preferences so that one can have a preferred target settings
-for each project (and environment variable and the current directory would
-be searched for the project preference file -- global preferences would
-still come from the users's home directory).
-
---
-
-Reactivate the "Use this target?" confirmation box.  Do it independently of
-the above?
-
---
-
-Add option to activate the Source Window from the signal popup box when
-the inferior program is signaled.
-
-                     Code Cleanups
-                     =============
-
-Reorganize the Source Memory code.
-
---
-
-Clean up the class hierarchy.
-
---
-
-Migrate to Tcl/Tk 8.3.2
-
---
-
-Try BLT tree as an alternative to the Tix Tree, so we can drop Tix altogether.
-
---
-
-Optional use of installed Tcl/Tk (keeping it available on the distribution)
-
---
-
-Fix the gdbtk testsuite.
-
---
-
-Enhance the test harness, perhaps migrating to the new SourceNavigator testing
-system.
-
-                 Architectural Improvements
-                 ==========================
-
-Decouple the GUI from gdb, running them as separate processes.
-
---
-
-Separate the Tcl part from the Tk part to facilitate scripting.
-
-                        Bug Fixes
-                        =========
-
-Fix process attach, specially the process listing code.
-
-Fix Source Window so that Key shortcuts work (may not be possible without
-rewritting).
-
-Fix info popup annoyances (like trying to show a large array without even
-adding line breaks and showing up over right click menus).
-
-Fix command window command line recall that misses the arguments of
-commands that autoincrement their arguments.
-
-Fix function browser window problems.
-
-Maximization of a window affects preference sizing but forgets that maximized
-state was set.
-
-Taskbar "always on top" hides funcxtion combobox.
