binutils: Fix bugs found by -Wpointer-compare

The MIPS bug was introduced by upstream commit 7403cb630, which failed
to account for the additional indirection introduced and also dropped
one of the checks; change it to the standard "NULL-or-empty" check as
used elsewhere in BFD, which is also what upstream now has.

MFC r315522: use INT3 instead of NOP for x86 binary padding

We should never end up executing the inter-function padding, so we

MFC r327164:

Fix clang 6.0.0 compiler warnings in binutils

Latest clang git has a warning -Wnull-pointer-arithmetic which will
trigger a -Werror failure. Addition and subtraction from a null pointer
is undefined behaviour and could be optimized into anything.

Furthermore, using the difference between two pointers and casting the
result back to a pointer is not portable since the size of ptrdiff_t
does not necessary have to be the same as size of void* (this happens
e.g. on CHERI). Using intptr_t instead fixes this portability issue and
the compiler warning.

Upstream binutils also added the "octeon+" CPU, and the saa/saad

Replace local prototype of basename() with an inclusion of <libgen.h>.

libiberty currently defines the prototype for basename() itself instead
of using <libgen.h>. It still uses the BSD-style prototype instead of
the POSIX one, meaning that if FreeBSD would switch over to the POSIX
one, you wouldn't be able to use libiberty.h and libgen.h in a single
source file. It turns out that kgdb does this. Patch up libiberty to
just include <libgen.h>.

I'm currently talking to upstream to see whether we can come up with a
more complete solution that could be integrated, but for our
unmaintained copy of GDB in base, let's just apply the simplest

Unconditionally set e_ident[OSABI]=ELFOSABI_FREEBSD in arm binary headers.

When the armv6 support was imported from a project branch, this complex
conditional logic and related #define'd values came along, but it's really
not clear what the intent of it all was. The effect, however, was that
OSABI was always set to zero, which is "UNIX System V ABI". Having the wrong
value there causes pkg(8) to avoid looking inside arm elf binaries to
determine shared-lib required/provides info for packaging.

Add the MOVT/MOVW types to the list of relocs which do not generate .plt
entries. This fixes the segfaults in arm userland code compiled with
-march= or -mcpu= values that allow the compiler to generate movw/movt
sequences to load 32-bit constants.

Correct the code for sign-extending a 16 bit value. As near as I can tell
this is effectively a no-op -- the addend term in MOVT/MOVW relocations
always seems to be zero. But this is correct and the old code wasn't.

Improve collation string and locales support

The generated files are now identified as "BSD 1.0" format.

added to be able to generate locales and the Makefiles from the vanilla CLDR

Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental.

This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.

armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
* WITH_ARM_EABI
* WITHOUT_GCC
* WITHOUT_GNUCXX

In addition, without an external toolchain, the following need to be left
as their default:
* WITH_CLANG
* WITH_CLANG_IS_CC

As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.

Make gas accept any PowerPC instruction by default. This is a local change,
and will not be submitted upstream.

Merging of projects/armv6, part 3

Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions. In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
* GCC to default to arm1176jz-s
* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K
* uname -p to return 'armv6'
* make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use

Rename the linker emulation name for powerpc and powerc64. This is needed that

With retirement of cpumask_t and usage of cpuset_t for representing a

Remove them and replace their usage with custom pc_cpuid magic (as,
atm, pc_cpumask can be easilly represented by (1 << pc_cpuid) and
pc_other_cpus by (all_cpus & ~(1 << pc_cpuid))).

This change is not targeted for MFC because of struct pcpu members

etire the cpumask_t type and replace it with cpuset_t usage.

This is intended to fix the bug where cpu mask objects are
capped to 32. MAXCPU, then, can now arbitrarely bumped to whatever
value. Anyway, as long as several structures in the kernel are
statically allocated and sized as MAXCPU, it is suggested to keep it
as low as possible for the time being.

Technical notes on this commit itself:
- More functions to handle with cpuset_t objects are introduced.
The most notable are cpusetobj_ffs() (which calculates a ffs(3)
for a cpuset_t object), cpusetobj_strprint() (which prepares a string
representing a cpuset_t object) and cpusetobj_strscan() (which
creates a valid cpuset_t starting from a string representation).
- pc_cpumask and pc_other_cpus are target to be removed soon.
With the moving from cpumask_t to cpuset_t they are now inefficient
and not really useful. Anyway, for the time being, please note that
access to pcpu datas is protected by sched_pin() in order to avoid
migrating the CPU while reading more than one (possible) word
- Please note that size of cpuset_t objects may differ between kernel
and userland. While this is not directly related to the patch itself,
it is good to understand that concept and possibly use the patch
as a reference on how to deal with cpuset_t objects in userland, when
accessing kernland members.
- KTR_CPUMASK is changed and now is represented through a string, to be
set as the example reported in NOTES.

Please additively note that no MAXCPU is bumped in this patch, but
private testing has been done until to MAXCPU=128 on a real 8x8x2(htt)
machine (amd64).

Please note that the FreeBSD version is not yet bumped because of
the upcoming pcpu changes. However, note that this patch is not
targeted for MFC.

Add .interp back into INITIAL_READONLY_SECTIONS in MIPS n64 ABI.

The binutils update in r218822 caused the MIPS n64 dynamic binaries to
fail because the ".interp" section is not in the initial sections.
This happens because elf64bmip-defs.sh overrides INITIAL_READONLY_SECTIONS
to add ".MIPS.options" sections instead of the ".reginfo" section used
by n32.
This used to work fine, but after r218822, INITIAL_READONLY_SECTIONS also
contains the .interp section, so the override has to be done differently.

In the upstream rev. 1.61 of elf64-sparc.c the following bug was fixed:

* elf64-sparc.c (sparc64_elf_relocate_section): Adjust addend of
dynamic relocs against section symbols for the output section vma.

However, with the addition of TLS support in the upstream rev. 1.104
this fix was essentially reverted. After factoring out the common parts
of elf32-sparc.c and elf64-sparc.c a comment was added to elfxx-sparc.c
in the upstream rev. 1.27 as part of unrelated changes, saying that the
fix from elf64-sparc.c rev. 1.61 indeed should be implemented, but given
that some unspecified OS has a broken ld.so expecting broken relocations
deliberately is omitted.
As the current behavior actually violates the SPARC ABI, FreeBSD never
had such a broken ld.so and this is actually causing problems with at
least kernel modules linked with binutils 2.17.50 committed in r218822
without the workaround committed in r219340 in place, re-implement the
above fix in a way so that is only applied if the output format is
ELFOSABI_FREEBSD. In the upstream version it probably would make sense
to invert this check and only skip adjusting the addend for the OS with
the broken ld.so, once it's determine which one that is.

- For cores, a new ELF note is added (NT_THRMISC) that can be used for

binutils/ld: fix incorrect placement of __start_SECNAME in some cases

__start_SECNAME and __stop_SECNAME symbols are automatically generated
by ld for orphan sections, i.e. those not explicitely referenced by a
linker script. The symbols are supposed to be placed correspondingly
at the start and the end of the section in output file. In some cases
__start_SECNAME may be placed at the address after the end of the
previous section (if any) and before the start the section. This
happens when following conditions are met:
1. the orphan section is found in more than one input file
2. the orphan section has different alignment requirements across input
files
3. the first instance of the section encountered doesn't have the
greatest alignment requirement
In these conditions resulting output section will be placed at address
after the end of the previous section aligned to the greatest alignment
requirement in the inputs, but __start_SECNAME will be placed at address
after the end of the previous section aligned to the alignment
requirement of the first input in which the section is encountered.

See commit message of r196118 for a concrete example of problems caused
by this bug.

The fix is to place __start_SECNAME inside the section and use ABSOLUTE
directive, rather than placing __start_SECNAME outside the section and
trying to guess address alignment.

This fix is in line with upstream binutils change/fix made between
versions 2.19 and 2.20 in revision of 1.307 ldlang.c.

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.

Revert this file back to its FSF/Cygnus virgin state.
With jb's rev 1.2 commit to usr.bin/lorder/lorder.sh we don't depend on
the 4.4BSD's ``nm -o'' behavior.

Previous to 4.3BSD-Reno, ``nm -o'' did not output the .o's filename on a
line by itself. The change occurred between CSRG's nm.c rev 4.8 (1987) and
rev 5.1 (in 1989), which was "new version from Hans Huebner hans@garp.mit.edu,
huebner@db0tui6.BITNET". The Binutils maintainers would rather cater to
a loud boisterous user of 4.3BSD VAXen which has its own native toolchain,
rather than a modern Unix with multiple orders of magnitude more users
and in which Binutils *is* the native toolchain.

Rev 1.3 which resolved conflicts in the 2.9.1 import, used a comment from

Change our ELF binary branding to something more acceptable to the Binutils
maintainers.

After we established our branding method of writing upto 8 characters of
the OS name into the ELF header in the padding; the Binutils maintainers
and/or SCO (as USL) decided that instead the ELF header should grow two new
fields -- EI_OSABI and EI_ABIVERSION. Each of these are an 8-bit unsigned
integer. SCO has assigned official values for the EI_OSABI field. In
addition to this, the Binutils maintainers and NetBSD decided that a better
ELF branding method was to include ABI information in a ".note" ELF
section.

With this set of changes, we will now create ELF binaries branded using
both "official" methods. Due to the complexity of adding a section to a
binary, binaries branded with ``brandelf'' will only brand using the
EI_OSABI method. Also due to the complexity of pulling a section out of an
ELF file vs. poking around in the ELF header, our image activator only
looks at the EI_OSABI header field.

Note that a new kernel can still properly load old binaries except for
Linux static binaries branded in our old method.

*
* For a short period of time, ``ld'' will also brand ELF binaries
* using our old method. This is so people can still use kernel.old
* with a new world. This support will be removed before 5.0-RELEASE,
* and may not last anywhere upto the actual release. My expiration
* time for this is about 6mo.
*

Slight cleaner code that may be more palatable to the Binutils maintainers.

Turn a warning into an error. Occurances of that warning generate bad
-fpic code that damages symbol locations at runtime.

The only know occurance in our tree (src and ports) was locatime.c,
which was just changed to generate code that doesn't trigger the
problem.

This is a workaround, the real cause is that our gas doesn't
understand code our gcc generates for some -O -fpic code. They are
expected to be back in sync soon, but until then (including
4.0-RELEASE) we need to prevent people from using bad -fpic code.

ld was kinly looking up the Linux /etc/ld.so.conf (which we don't have).
Teach it about the FreeBSD equivalent, because there are some funny things
going on with -rpath that I can't quite get a handle on. It looks like
setting an rpath on a new shared object overrides all the implicit
DT_RPATH's from the dependencies, causing them to fail at link time
(but not runtime).

Restore traditional behaviour by allowing tabs in strings. In deference
to the new age of internationalisation, I used isblank() instead of a
literal '\t'.
