c8c62548bf Don't add -Winline for WARNS=6
This warning is very rarely useful (inline is a hint and not mandatory).
This flag results in many warnings being printed when compiling C++
code that uses the standard library with GCC.

This flag was originally added in back in r94332 but the flag is a no-op
in Clang ("This diagnostic flag exists for GCC compatibility, and has no
effect in Clang"). Removing it should make the GCC build output slightly
more readable.

61f66a1f44 ncurses: Add support for terminfo database
Along with the termcap database, ncurses will now lookup for the
terminfo database, note that the terminfo database is being looked
up first and then it fallsback on the termcap one.

While here drop our custom reader for the termcap database, over the
time it is needed maintenance to be able to catchup with changes on ncurses
side.

Install the ncurses tools which are needed to deal with the terminfo
database: tic, infocmp, toe

Replace our termcap only aware tools with the ncurses counterpart:
tput, tabs, tset, clear and reset

In particular they can your the extra capabilities described in the
terminfo database, which does not exist in termcap

Note that to add a new terminfo information to the database from ports
the ports will just need to add their extra information into:
/usr/local/share/site-terminfo/<firstletteroftheterm>/<term>

flags for building OS. It allows to enable the ASLR

9c6954329a bsd.compiler.mk: Detect distribution-provided GCC when executed as cc
Clang always prints "clang $VERSION" regardless of the name used to
execute it, whereas GCC prints "$progname $VERSION", meaning if CC is
set to cc and cc is GCC it will print "cc $VERSION". We are able to
detect some of those cases since it then prints "($PKGVERSION)", where
the default is "GCC", but many distributions override that to print
their name and the package version number (e.g. "Debian 10.2.1-6"), so
nothing tells us it's GCC other than the fact that it's not Clang (and
that there's an FSF copyright disclaimer).

However, GCC's -v option will always print "gcc version $VERSION", so
fall back on using that to detect GCC. Whilst Clang also supports this
option, we should never get here, so Clang handling is not added.

WITHOUT_LIBTHR has been broken for a little over five years now, since the

Additionally, in the five plus years that it's been broken more reverse
dependencies have cropped up in libzstd, libsqlite3, and libcrypto (among
others) that make it more and more difficult to reconcile the effort needed
to fix these options.

Remove the broken options.

986deea5b5 build: make check: use a PATH search instead for Kyua
which(1) accepts both relative/absolute paths as well as lone binary
names.  Set KYUA to kyua and use which(1) to confirm that it can find one;
if it cannot, just advise the user to set KYUA directly to the kyua binary
rather than assuming a relative location from LOCALBASE.

This allows `make check` to be operated with the version of kyua in base
without losing the flexibility of specifying another one.

ngie@ notes that the original intention was to avoid redundant $PATH lookups
and improve the determinism of the target. A future change will likely push
us back to this state, perhaps in the form of reverting this entirely and
just switching to using kyua in base. Accepting any in $PATH should be
considered a transitional move, at least until it's declared otherwise,
since kyua was only semi-recently added to base.

We don't stage lib32 libraries in WORLDTMP/usr/lib32 and doing so doesn't
buy much.  If we want to use a staged lib32 library then we need to look in
LIBCOMPATTMP where they were staged.  For example if LIBC_PIC were wanted then

b82a9ec5f5 src.opts.mk: switch to bsdgrep as /usr/bin/grep

some day. Switch to the BSDL grep implementation now that it's been a
little more thoroughly tested and theoretically supports all of the
extensions that gnugrep in base had with our libregex(3).

Folks shouldn't really notice much from this update; bsdgrep is slower than
gnugrep, but this is currently the price to pay for fewer bugs. Those
dissatisfied with the speed of grep and in need of a faster implementation
should check out what textproc/ripgrep and textproc/the_silver_searcher
can do for them.

I have some WIP to make bsdgrep faster, but do not consider it a blocker
when compared to the pros of switching now (aforementioned bugs, licensing).

dabbf11f97 bsd.lib.mk: Work around build system raciness
We are seeing regular build failures due to libc.so being installed again and
another parallel make job tries to read the partially written libc.so at the
same time. When building with -j32 or higher this almost always happens on
the first clean build (subsequent incremental builds always work fine).
Using -S should "fix" the "section header table goes past the end of the
file: e_shoff = 0x..." errors that have started to plague our builds.

We originally thought this only affected CheriBSD, but I just got the same
error while building the latest upstream FreeBSD.

The real fix should be to not install libraries twice, but until then this
workaround is needed.

e268fd0a02 Support initializing stack variables on function entry
There are two options:
 - WITH_INIT_ALL_ZERO: Zero all variables on the stack.
 - WITH_INIT_ALL_PATTERN: Initialize variables with well-defined patterns.

The exact pattern are a compiler implementation detail and vary by type.
They are somewhat documented in the LLVM commit message:
https://reviews.llvm.org/rL349442
I've used WITH_INIT_ALL_* to match Microsoft's InitAll feature rather
than naming them after the LLVM specific compiler flags.

In a range of consumer products, options like these are used in
both debug and production builds with debugs builds using patterns
(intended to provoke crashes on use of uninitialized values) and
production using zeros (deemed more likely to lead to harmless
misbehavior or NULL-pointer dereferences).

9fa94e1c09 Turn on WITH_LLVM_CXXFILT by default
LLVM's demangler supports more modern C++ constructs such as lambdas and
unnamed types, and is actively maintained. The command line tool is
usable as a drop-in replacement for GNU c++filt, or elftoolchain's
cxxfilt. The latter is still available by using WITHOUT_LLVM_CXXFILT, if
needed.

07bab4417d Add WITH_LLVM_CXXFILT option to install llvm-cxxfilt as c++filt
Since elftoolchain's cxxfilt is rather far behind on features, and we
ran into several bugs, add an option to use llvm-cxxfilt as an drop-in
replacement.

It supports the same options as elftoolchain cxxfilt, though it doesn't
have support for old ARM (C++ Annotated Reference Manual, not the CPU)
and GNU v2 manglings. But these are irrelevant in 2020.

Note: as we already compile the required libraries as part of libllvm,
this will not add any significant build time either.

3f8d55c617 Remove --ld-path=* from _LDFLAGS
It makes no sense to pass --ld-path to direct ${LD} invocations.

This was missed in r366270 due to not doing a clean build.

2cef3afd7b Stop using -O instead of -O2 for MIPS
Until clang 11 that was equivalent to -O2, but clang changed it to -O1 so
generated MIPS code will now be unnecessarily slow. It also removes a weird
special case from sys.mk.
This is similar to the D26471 change for debug kernels and should not change
anything since everything was previously building MIPS code at -O2 until the
clang 11 update.

c3d67d6cf0 Don't use install(1) for the library symlinks in the build directory
It appears this was changed from ln to use install in rS245752. I noticed
this because my buildenv was setting INSTALL=install -U -M //METALOG
and then these links fail to be created with the following error:
install: open //METALOG: Permission denied
