7996bf419b kgdb: correctly map sections to addresses in elf object modules (amd64)
Unlike for modules with dso type, in elf object modules all the sections
have virtual address of zero.  So, it is insufficient to add module base
address to section virtual address (as recorded in section header) to
get section address in kernel memory.
Instead, we should apply the same calculations that are performed by
kernel loaders (in boot code and in kernel) when they lay out sections
in memory.

2cf64c8006 Teach our toolchain how to generate 64-bit PowerPC binaries. This fixes
a variety of bugs in binutils related to handling of 64-bit PPC ELF,
provides a GCC configuration for 64-bit PowerPC on FreeBSD, and
associated build systems tweaks.

4935d54b6a Mention the radiolist option in the man page. It is being listed when
dialog(1) is run without arguments and works as expected. Therefore,
it should be part of the manual as well.

Note: dialog(1) has not been updated for many years and is not actively
maintained at the moment.

d12582eb67 Add an alignment of 8 for sections in the n32 ABI. The default alignment
of of 4 causes _end to be word aligned, which will be returned by sbrk.

malloc(3), when compiled for n32, expects sbrk to return an 8-byte aligned
value.

15744a9c4c Often reported issue with newer ld is:
error in /usr/lib/crtendS.o(.eh_frame); no .eh_frame_hdr table will be created.

The issue is that crtend is compiled with unwind table, and also it
places the special CIE into the .eh_frame indicating the end of section,
that is located before generated unwind table. New ld has assertion that
verifies that closing CIE is indeed the last CIE, causing the crypting
message to be issued, and refusing to generate dwarf unwind.

Add -fno-asynchronous-unwind-tables to disable unwind table generation
for crtbegin/crtend. While there, disable omitting the frame pointer [1].

8da70fdc42 Fix build for O32 systems without a TARGET_CPUTYPE defined. We must default to
MIPS-III because FreeBSD relies on a number of MIPS-III features; the ABI
default would be MIPS-I which we don't intend to support.  Our old default
before I switched to using the ABI default was MIPS32.

5619a3e4bf Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.
o) Add TARGET_ABI to the MIPS toolchain build process.  This sets the default
   ABI to one of o32, n32 or n64.  If it is not set, o32 is assumed as that is
   the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE.  This is
   necessary to have a working "cc" if e.g. mips64 is specified, as binutils
   will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC.  Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
   --end-group.  This is required for static linking to work on n64 with the
   interdependencies between libraries there.  This is what other OSes that
   support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
   former being what libgcc, etc., check and the latter seemingly being a
   misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
   ISA from the ABI.  Our old defaults were too liberal and assumed that 64-bit
   ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
   the MIPS32 ISA, when we are supporting or will support some systems based on
   earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
   and add flags and code necessary to support Octeon-specific instructions.
   This should also make merging opcodes for other modern architectures easier.

d578fbb66e Make this directory more regular. Since it is one we control, use the
freebsd-based names for filenames.  This allows us to eliminate
almost all of the uses of ${MACHINE_ARCH} here to do special things, and
instead we use it to include filenames.  This makes new architectures easier
to support.
