18b17e97757a59718a23f8128dfc91c016df08b1 07-Jun-2014 Elliott Hughes <enh@google.com> Add a regression test for two libm bugs we didn't have.

Reported on the OpenBSD list, but we already had the fix for one from FreeBSD,
and I think the other only affected ld80 anyway. Worth having tests thuogh.

9a5a3e8e74e2c6d7850ab29711189acf0f7378a2 06-May-2014 Elliott Hughes <enh@google.com> Fix <math.h> to quieten most of our warnings.

I've reported the wcsftime bug upstream, but we really just want to use -D
to ensure the buggy code isn't built. (I've also brought our strftime a bit
closer to upstream now we have the right define.)

I don't think upstream is likely to fix all their sign-compare and
uninitialized warnings, so let's just silence them.

As for libm, again upstream isn't likely to fix all their warnings, and
silencing those made the ones that were our fault stand out. I've fixed
our <math.h> to fix the warnings caused by our lack of definitions for
the non-imprecise long-double functions. I checked the C99 standard, and
all these functions are there.

- promoted IEEEld2bits to fpmath since most of the where the same for
diffrent archs
- removed _fpmath
- reinstated weak_references
- moved isfinite and isnormal to libc
- clean up fake_long_doubles
- clean up some useless ifdefs
- added missing nexttoward* tests

02c78a386739a8a2b3007efeb00a9ca04132100a 12-Apr-2014 Elliott Hughes <enh@google.com> Reimplement isinf/isnan/fpclassify.

Also move isinf and isnan into libc like everyone else.

Also move fpclassify to libc like the BSDs (but unlike glibc). We need
this to be able to upgrade our float/double/long double parsing to gdtoa.

Also add some missing aliases. We now have all of:

isnan, __isnan, isnanf, __isnanf, isnanl, __isnanl,
isinf, __isinf, isinff, __isinff, isinfl, __isinfl,
__fpclassify, __fpclassifyd, __fpclassifyf, __fpclassifyl.

* reworked amd64/_fpmath.h and arm64/_fpmath.h to support 128-bit long
doubles.
* improved tests to cover long double cases
* made modfl an alias for LP32

Tests pass on x86, x86_64, arm, arm64 and mips.

5f6f4a956cd630f873fe41058e96262f897f4bc9 19-Feb-2014 Narayan Kamath <narayan@google.com> Fix signbit / infinite / isinf / isnan unit tests.

Turns out stlport isn't broken. <cmath> (included
transitively via gtest in our case) is not required
to make C99 math macros (like signbit) available, nor is
it required to preserve them if they're already defined.
It is only required to make the equivalent functions in
namespace std available.

I couldn't find any documentation of required behaviour for
programs that include both <math.h> and <cmath>.

I've verified experimentally that llvm's libc++ and gnu
stl behave the same as stlport.

f04935c85e0b466f0d30d2cd4c0fa2fff62e7d6d 21-Dec-2013 Christopher Ferris <cferris@google.com> Make sure that the same tests are on all platforms.

In order to be able to generate a list of tests for cts, the same set of
tests must exist across all platforms. This CL adds empty tests where a
test was conditionally compiled out.

This CL creates a single library libBionicTests that includes all of
the tests found in bionic-unit-tests-static.

Also fix a few missing include files in some test files.

Tested by running and compiling the tests for every platform and
verifying the same number of tests are on each platform.

a0ee07829a9ba7e99ef68e8c12551301cc797f0f 31-Jan-2013 Elliott Hughes <enh@google.com> Upgrade libm.

This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies
the set of functions we support on ARM, MIPS, and x86, fixes "long double",
adds ISO C99 support, and adds basic unit tests.

It turns out that our "long double" functions have always been broken
for non-normal numbers. This patch fixes that by not using the upstream
implementations and just forwarding to the regular "double" implementation
instead (since "long double" on Android is just "double" anyway, which is
what BSD doesn't support).

All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.
