0a1ba8ecaa When NETBSD_NATIVE, use the appropriate version of libgcc for the compile 
mode:  libgcc_pic.a for -shared, and libgcc_p.a for -p[g].

a3aeedcdb7 Tag all version strings with "nb1" to make FSF/binutils/gcc/gdb people 
happy.  (This flags the version as deviating from the official FSF
distribution inside the NetBSD source tree.)

06811a827d Go back to the nop/unop pattern, and pick up rev. 1.35 from the 
master FSF sources (rth):

f87b859f0d After a discussion with Richard Henderson (rth at redhat dot com), add 
the patch I posted to tech-toolchain@netbsd.org as a workaround for the
GOT bug whereby the callee-saved register %a5 can be trashed in certain
optimised -fPIC functions.

This may yet need to be fixed a different way, pending input from
Andreas Schwab on his change in revison 1.33 of this file in the
FSF source...

In the meantime, I've built and installed several NetBSD shared libraries
(including libc) with my change and found no problems.

elf64alpha_nbsd linker emulation that sets the entry point correctly

e3e5021be2 We need the versions of ASM_DECLARE_FUNCTION_NAME and 
ASM_DECLARE_FUNCTION_SIZE from <alpha/alpha.h>, but <netbsd.h>
re-defines them.  So, re-define them again here to what
we need.

80ed7d6a42 Clean up a bunch of the ELF support (looks like there was some sort 
of merge error), and make the function/object type/size macros work

85d454e712 Reset ENTRY to __start (this was changed to _start in rev 1.5 
of this file in the master FSF sources; I obviously disagree
with the change, since it was apparently made to appease one
particular OS, even though previous binutils releases had been
made with ENTRY=__start, and have brought it up on
binutils@sources.redhat.com).

f589c8c881 Make sure SET_ASM_OP is undefined; the Alpha assembler uses .set

7a3fcb2adf Convert unaligned relocs to aligned relocs if they happen to be

3ec17be693 Applied a strength-reduction patch from gcc-current. The patch 
is in their revision 1.186, from schwab@suse.de, and said:

  Don't call reg_used_between_p if the insn from BL2 is after
  the insn from BL.

This fixes a cc1 SEGV on sys/dev/scsipi/ch.c rev 1.48 under -O2 or -Os,
seen on m68k and vax.

4cac6e8609 * Overhaul: 
* move the code that supplies the integer and FP registers into
    separate functions, rather than duplicating the code for the
    ptrace and core file cases.
  * Use supply_register() rather than just copying directly into
    the register array and calling registers_fetched().  This way,
    only the registers actually supplied are marked as valid within
    the debugger.
* Add support for SSE/SSE2 registers via the PT_{GET,SET}XMMREGS
  ptrace(2) request.

(Blocked on the FSF assignment clerk for feeding this back to
the master GDB sources.)

49df24a942 Add MIPS (both target and host) support to the NEW_TOOLCHAIN GDB, based on 
the 4.17 NetBSD support from our tree.  Original port by Chris Sekiya, with
minimal tweaks and cleanups by me (mainly: build bi-endian by default, add
NetBSD kcore support back).
