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.
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.

utilities and related support files for manual pages, which were previously
controlled by MAN. For POLA, the default depends on MAN, i.e., WITHOUT_MAN
implies WITHOUT_MAN_UTILS and WITH_MAN implies WITH_MAN_UTILS. This patch
is slightly improved by me from:
PR: misc/145212
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.
Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

Note that this is actually a no-op for most users, as this GNU
cpio was broken on -HEAD and 8-STABLE since last March until
the recent fix.
FreeBSD 8.0+ uses BSD cpio by default and the code is being
actively maintained.

kvm_nlist skips lookup for entries that have n_type != N_UNDF.
N_UNDF happens to be zero, so n_type typically has a correct
value by accident, but not always.
Note: jhb has a patch that replaces kvm_nlist use with direct
gdb parsing.

compatibility level with the GNU counterparts and have shown to be mature
enough. For now, the GNU versions aren't removed from the tree, just detached
from the build.

Use libssp_nonshared library to pull __stack_chk_fail_local symbol into
each library that needs it instead of pulling it from libc. GCC
generates local calls to this function which result in absolute

loader do extra work every time given shared library is being relocated
and making affected text pages non-shareable.
