This version omits the printing of a copyright header in interactive mode
and the dc command now exits after execution of the commands passed via -e
or -f instead of switching to interactive mode. To pass further commands
via STDIN when dc has been invoked with -e or -f, add "-f -" to the
parameter list.
This revision worked around an endless recursion when compiling clzdi2.c
and ctzdi2.c with gcc, upstream landed a different workaround for this
in https://reviews.llvm.org/rL324593, which is effective enough.

Merge lld trunk r321017 to contrib/llvm/tools/lld.
(Note that in this merge, I foolishly combined upstream changes with
this local change. But only this ifdef part is really needed, as we
always default to ELF link mode.)
Since this is contrib code, create an upstreamable version of my
change. Now on FreeBSD and NetBSD if _STANDALONE is defined, we
include the kernel version with alloances for the quirky differences
between the two.

RISC-V is extensible ISA and the idea here is to have built-in define

libunwind: make __{de,}register_frame compatible with libgcc API
The libgcc __register_frame and __deregister_frame functions take a
pointer to a set of FDE/CIEs, terminated by an entry where length is 0.
In Apple's libunwind implementation the pointer is taken to be to a
single FDE. I suspect this was just an Apple bug, compensated by Apple-
specific code in LLVM.
See lib/ExecutionEngine/RuntimeDyld/RTDyldMemoryManager.cpp and
http://lists.llvm.org/pipermail/llvm-dev/2013-April/061737.html
for more detail.
This change is based on the LLVM RTDyldMemoryManager.cpp. It should
later be changed to be alignment-safe.

Reapply r351610:
Update libunwind custom frame register and deregister functions for
FreeBSD: use the new doubly underscored names for unw_add_dynamic_fde
and unw_remove_dynamic_fde.
NOTE: this should be upstreamed...
Reapply r230021 (by ed):
Add a workaround to prevent endless recursion in compiler-rt.
SPARC and MIPS CPUs don't have special instructions to count
leading/trailing zeroes. The compiler-rt library provides fallback
rountines for these. The 64-bit routines, __clzdi2 and __ctzdi2, are
implemented as simple wrappers around the compiler built-in
__builtin_clz(), assuming these will expand to either 32-bit
CPU instructions or calls to __clzsi2 and __ctzsi2.
Unfortunately, our GCC 4.2 probably thinks that because the operand is
stored in a 64-bit register, it might just be a better idea to invoke
its 64-bit equivalent, simply resulting into endless recursion. Fix this
by defining __builtin_clz and __builtin_ctz to __clzsi2 and __ctzsi2
explicitly.
Reapply r276851:
Update compiler-rt to trunk r224034. This brings a number of new
builtins, and also the various sanitizers. Support for these will be
added in a later commit.
master 2e10b7a39b9, the last commit before the llvmorg-12-init tag, from
which release/11.x was branched.
Note that for now, I rolled back all our local changes to make merging
easier, and I will reapply the still-relevant ones after updating to
11.0.0-rc1.
In IEEE 1003.1-2008 [1] and earlier revisions, BRE/ERE grammar allows for
any character to be escaped, but "ORD_CHAR preceded by an unescaped
<backslash> character [gives undefined results]".
Historically, we've interpreted an escaped ordinary character as the
ordinary character itself. This becomes problematic when some extensions
give special meanings to an otherwise ordinary character
(e.g. GNU's \b, \s, \w), meaning we may have two different valid
interpretations of the same sequence.
To make this easier to deal with and given that the standard calls this
undefined, we should throw an error (EESCAPE) if we run into this scenario
to ease transition into a state where some escaped ordinaries are blessed
with a special meaning -- it will either error out or have extended
behavior, rather than have two entirely different versions of undefined
behavior that leave the consumer of regex(3) guessing as to what behavior
will be used or leaving them with false impressions.
This change bumps the symbol version of regcomp to FBSD_1.6 and provides the
old escape semantics for legacy applications, just in case one has an older
application that would immediately turn into a pumpkin because of an
extraneous escape that's embedded or otherwise critical to its operation.
This is the final piece needed before enhancing libregex with GNU extensions
and flipping the switch on bsdgrep.

This version fixes a regression with regard to tradtional behavior of the
non-standard FreeBSD option "-e". In the previous version "-e quit" caused
bc to exit before any computations had been performed, since all -e option
parameters were concatenated and parsed as a whole, with quit causing the
program to exit as soon as it was parsed. This version parses and executes
commands passed with -e one by one and only exits after all prior commands
have been executed.
This commit is not a SVN merge, since the vendor import had been performed
after the import to contrib. Instead the contents of contrib/bc has been
removed and the new version is copied over unchanged from vendor/bc/dist.
A file update in 2018 broke many ports as it misidentified shared
libraries as PIE binaries. r333944 reverted part of the change,
restoring ports builds but misidentifying objects in the opposite
direction.
Earlier this month file 5.39 was imported, and then the change
originally from r333944 was recommitted as r362261. However, the
issue was fixed upstream, so r362261 serves no purpose.

These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:
- They do not depend on external large number functions (i.e. no dependency
on OpenSSL or any other large number library)
- They implements all features found in GNU bc/dc (with the exception of
the forking of sub-processes, which the author of this version considers
as a security issue).
- They are significantly faster than the current code in base (more than
2 orders of magnitude in some of my tests, e.g. for 12345^100000).
- They should be fully compatible with all features and the behavior of the
current implementations in FreeBSD (not formally verified).
- They support POSIX message catalogs and come with localized messages in
Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
and Russian.
- They offer very detailed man-pages that provide far more information than
the current ones.
The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.
Installation of this version is controlled by the option "MK_GH_BC=yes".
This option will be set to yes by default in 13-CURRENT, but will be off
by default in 12-STABLE.
