Kwok Cheung Yeung e18743072b amdgcn: Add vectorized math routines
This implements a set of vectorized math routines to be used by the
compiler auto-vectorizer.  Versions for vectors with 2 lanes up to
64 lanes (in powers of 2) are provided.

These routines are based on the scalar versions of the math routines in
libm/common, libm/math and libm/mathfp.  They make extensive use of the GCC
C vector extensions and GCN-specific builtins in GCC.

Jon Turney 81b7cf09fa Silence xsltproc when writing manpages
Unless make is invoked with V=1, have xmlto pass the parameter
'man.output.quietly=1' to xsltproc to suppress "Note: Writing foo.N"
output from the manpages stylesheet.

(This doesn't quite do what it says: The output is not silenced if V has
any value, including 0.  You could consider that either a bug or a
feature.)

Jon Turney d51aab2abd Add build avoidance for 'make man'
This will generate multiple manpage files as an output, but we don't
know what they will be called, so use a timestamp for build avoidance.

Jon Turney 3d64a500f1 Simplify rules for creating man pages
Simplify rules for creating docbook XML used to create manpages:
Updating the output using move-if-change and then unconditionally
touching the .stamp file doesn't make much sense.

Mike Frysinger fb42151a18 newlib: libm: integrate tests subdir
Integrate the old libm/test/ subdir into the main build.  It hasn't
been used in a long time causing the code to rot a bit.  I've fixed
some of those, but it still fails for many ports, so it's disabled
by default.  People who want to take a closer look can run:
$ make libm/test/test

Mike Frysinger ac9f8c46b1 newlib: libm: merge build up a directory
Convert all the libm/ subdir makes into the top-level Makefile.  This
allows us to build all of libm from the top Makefile without using any
recursive make calls.  This is faster and avoids the funky lib.a logic
where we unpack subdir archives to repack into a single libm.a.  The
machine override logic is maintained though by way of Makefile include
ordering, and source file accumulation in libm_a_SOURCES.

One thing to note is that this will require GNU Make because of:
	libm_a_CFLAGS = ... $(libm_a_CFLAGS_$(subst /,_,$(@D)))
This was the only way I could find to supporting per-dir compiler
settings, and I couldn't find a POSIX compatible way of transforming
the variable content.  I don't think this is a big deal as other
Makefiles in the tree are using GNU Make-specific syntax, but I call
this out as it's the only one so far in the new automake code that
I've been writing.

Automake doesn't provide precise control over the output object names
(by design).  This is fine by default as we get consistent names in all
the subdirs: libm_a-<source>.o.  But this relies on using the same set
of compiler flags for all objects.  We currently compile libm/common/
with different optimizations than the rest.

If we want to compile objects differently, we can create an intermediate
archive with the subset of objects with unique flags, and then add those
objects to the main archive.  But Automake will use a different prefix
for the objects, and thus we can't rely on ordering to override.

But if we leverage $@, we can turn Automake's CFLAGS into a multiplex
on a per-dir (and even per-file if we wanted) basis.  Unfortunately,
since $@ contains /, Automake complains it's an invalid name.  While
GNU Make supports this, it's a POSIX extension, so Automake flags it.
Using $(subst) avoids the Automake warning to get a POSIX compliant
name, albeit with a GNU Make extension.

Mike Frysinger 5c21b37214 newlib: fix mkdoc dependencies
Make sure we depend on the right name of mkdoc all the time, and that
the rules that need it (e.g. .def files) depend on it.

Mike Frysinger 6026ef29d8 newlib: move man page generation into top-level build
This allows building the libc & libm pages in parallel, and drops
the duplication in the subdirs with the chew/chapter settings.

The unused rules in Makefile.shared are left in place to minimize
noise in the change.

Mike Frysinger 3365bd2f7a newlib: libm: move manual into top-level build
This doesn't migrate all the docs, just the libm's manual (pdf/info).
This is to show the basic form of migrating the chew files.
