[BZ #10871]
* NEWS: List the languages which actually use the alternative
months feature in this release. Also explain that "alt_mon" and
"ab_alt_mon" are optional.
The value of 'cd.initialized' is left uninitialized before the
first invocation of 'crypt_r ()' in this test despite the fact
that it should be set to zero according to the API.

We don't have support for hp timing for now, even the i686 variant, which needs
to know the CPU speed.

This avoids assert definition conflicts if some of the headers used by
malloc.c happens to include assert.h. Malloc still needs a malloc-avoiding
implementation, which we get by redirecting __assert_fail to malloc's

This patch lays out the top-level orginazition of the RISC-V port. It
contains all the Implies files as well as various other fragments of
build infastructure for the RISC-V port. This contains the only change
to a shared file: config.h.in.
RISC-V is a family of base ISAs with optional extensions. The base ISAs
are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but
this port currently only supports RV64I based systems. Support for
RISC-V lives in in sysdeps/riscv. In addition to these ISAs, our glibc
port supports most of the currently-defined extensions: the A extension
for atomics, the M extension for multiplication, the C extension for
compressed instructions, and the F/D extensions for single/double
precision IEEE floating-point. Most of these extensions are handled by
GCC, but glibc defines various floating-point wrappers and emulation
routines as well as some atomic wrappers.
We support running glibc-based programs on Linux, the support for which
lives in sysdeps/unix/sysv/linux/riscv.

This patch implements various atomic and locking routines on RISC-V. We
mandate the A extension on Linux-capable RISC-V systems, so this can

This function is used by GCC to enforce ordering between data writes and
instruction fetches, and while we'd prefer that users rely on the GCC
intrinsic when possible this is user visible in case that's not
possible.

here.

* manual/math.texi: RISC-V supports _Float128 and _Float64x.
The RISC-V port contains a crti.S that simply contains a link to
PREINIT_FUNCTION (when defined). As this should be entirely generic,
Joseph Myers suggested that we update the generic init_array version to
contain this. Since RISC-V is the only user of init_array this won't
break any existing ports.

With the git checkouts of Hurd components in build-many-glibcs.py
involving running autoreconf, there's a risk that generated files
could be left behind by an old autoreconf run (if an old version of
the sources generates those files in the source directory but a new
version does not).
This patch avoids that by using git clean -dxfq when updating git
checkouts. In this patch, that's conditional on --replace-sources, to
avoid removing any local not-checked-in files someone may have in
their checkout unless the option has been specifically passed that
says it's OK to blow old checkouts away, complete with any local
changes to them.
* scripts/build-many-glibcs.py (Context.git_checkout): Use git
clean -dxfq for git updates when replacing sources.
The disabling of libcilkrts in build-many-glibcs.py has some
peculiarities. It's only for the final GCC build, not the initial
bootstrap one, whereas normally anything disabled for the final build
should be disabled for the bootstrap one as well. And it's only for
Hurd, when it's more natural by analogy with the libsanitizer
disabling to disable this library unconditionally, not only for
targets where it's known to break. This patch cleans up that
disabling accordingly, adding a comment so it's obvious it can be
removed once GCC 7 is too old to build glibc.
* scripts/build-many-glibcs.py (Config.build_gcc): Use
--disable-libcilkrts unconditionally, not just for the final GCC
build for Hurd.
This patch makes build-many-glibcs.py use Linux 4.15. Other glibc
updates for Linux 4.15 can wait until after the 2.27 release.
* scripts/build-many-glibcs.py (Context.checkout): Default Linux
version to 4.15.
