* | Clean up the ARM fenv.h, moving implementation details into fenv.c.Elliott Hughes2014-06-092-18/+14

* | AArch64: libm: Fix ARM64 fenv_t and refactor ARM64 libm implementation.Serban Constantinescu2014-06-092-135/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the ARM64 ABI for libm. fenv_t is now split in 32bit status and 32bit control. This mirrors the AArch64 FPU control and status registers (FPCR, FPSR). The patch also refactors the libm implementation for ARM64 into a finer grained control over the FPU registers. Bionic-benchmarks has been expanded with 3 more benchmarks for floating point operations. The new libm implementation for ARM64 performs better over all the math benchmarks available.

* | Fix <math.h> to quieten most of our warnings.Elliott Hughes2014-05-052-35/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | This was originally motivated by noticing that we were setting the wrong bits for the well-known tls entries. That was a harmless bug because none of the well-known tls entries has a destructor, but it's best not to leave land mines lying around. Also add some missing POSIX constants, a new test, and fix pthread_key_create's return value when we hit the limit. Change-Id: Ife26ea2f4b40865308e8410ec803b20bcc3e0ed1

* | Upgrade libm.Elliott Hughes2013-02-01282-7946/+7083
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
