ec5833a498 Add a copy of FreeBSD's lib/libc/aarch64/_fpmath.h.
This makes it possible to build OpenLibm on ARM64 CPUs.

bc8dd927a3 Use isfinite() instead of non-standard finite() function.
The finite() function got standardized under the name isfinite(). Its
use is therefore discouraged.

2870ed32b3 Update Make.inc to detect OpenBSD
With this patch I have been able to successfully compile Openlibm on OpenBSD 5.7 (x86_64) using the following command:

gmake GCC=egcc GXX=eg++ USEGCC=1 ARCH=x86_64

(I had to install gcc 4.9 from ports, as Openlibm does not compile with the default compiler shipped with OpenBSD 5.7, which is gcc 4.2.1).

f70240ded5 Add support for cross compiling with ARCH=name
This is rather basic. A clean is needed to get rid of artifacts from
previous runs with other architectures.

Note this requires PR #88 to work because without it x86 is broken.

Closes #89

this no longer works with modern compilers. #55.

d64ea4e5f9 Make small changes to libm-test.c to improve portability.
- Don't define llabs(). This breaks if llabs() is already a macro, which
  is allowed by the C standard/POSIX. llabs() was introduced in C99, so
  I think we can safely assume it is present on all interesting systems.

- Cast the parameters to fabs() to the floating point type. Clang has
  introduced some interesting warnings that trigger if the arguments to
  fabs*() are not the right type.

b6ff8bbe91 Clean up a change that I sneaked in accidentically.
I often build the code with -Wmissing-prototypes to ensure that we don't
accidentically pollute the symbol namespace. If we want to provide a
symbol such as isopenlibm(), make sure we also declare it in
<openlibm_math.h>.

7e5585aaca Rename openlibm.h to openlibm_math.h.
This is a bit more consistent with the naming of the other header files
(openlibm_complex.h and openlibm_fenv.h). Re-add an openlibm.h header
that includes all of the public headers as a shorthand.

Fix up all of the source files to include <openlibm_math.h> instead of
<openlibm.h>. While there, fix ordering of the includes.

bc3f903bc2 Move public headers into include/ and private headers into src/.
While there, also modify the install target. We should make sure to
install all openlibm*.h headers. There is still some work to be done:
openlibm_fenv_*.h still depends on some additional bits. I'd propose
that we eventually create an include/openlibm_cdefs.h that contains all
of the macros we need.

23b8f663d4 Revert "Don't use __weak_reference() when a __strong_reference() is needed."
Unlike the __weak_reference() macro, __strong_reference() does type
checking. It can only create the reference if the type of the source and
the destination function match exactly.

Even if double == long double in practice, they remain unequal at the
language level.

d07820351b Rename the fenv headers.
I guess the idea would be to eventually also install all of the
openlibm*.h headers, instead of just openlibm.h. Make openlibm_fenv.h
suitable for this purpose by moving all of the $ARCH/fenv.h headers next
to it.

We actually need this change to make OPENLIBM_USE_HOST_FENV_H work.
Right now it's still broken, because the "#include <fenv.h>" performed
by openlibm_fenv.h still pulls in $ARCH/fenv.h as $ARCH/ is added to the
compiler include path.

9ab9db387d Don't use __weak_reference() when a __strong_reference() is needed.
OpenLibm uses the __weak_reference() macro for platforms where double
and long double use the same layout. That way functions only need to be
provided by the library once. The point is, in this specific case we
want to use strong references; not weak references.

Strong references can be used to give a symbol a second name. If you
look at the resulting object file, you will have two symbols with the
same offset and size. Weak references are different, in the sense that
they are marked in such a way that they act as fallbacks. They are only
used if an explicitly matching symbol is missing.

c253db68ca Add a new compilation flag: OPENLIBM_ONLY_THREAD_SAFE.
The global signgam variable is only part of the X/Open System
Interfaces. It is not part of the POSIX base definitions nor the C
standard.

I'd rather have it disabled for my specific use-case, so introduce a new
compilation flag that we can use to disable it.

42177873f8 Remove weak reference construct from fenv code.
I grepped through the FreeBSD source tree and for me, it seems to be
totally unclear why these two specific functions are weak references.
Such a construct is commonly used by FreeBSD's threading library
(libthr) to override certain functions, but I can't find any traces of
that.

Just use the function name directly. This fixes a compiler warning as
well (-Wmissing-prototypes).

06dbb6e72b Use more uniform style of including headers.
Put external headers before internal ones. While there, replace a lot of
occurences of "openlibm.h" with <openlibm.h>. It should be thought of as
an external header, as it is installed along with the library.
