* Cache getpid.Elliott Hughes2014-06-201-0/+11
| | | | | | | | | | | | | | | | | In practice, with this implementation we never need to make a system call. We get the main thread's tid (which is the same as our pid) back from the set_tid_address system call we have to make during initialization. A new pthread will have the same pid as its parent, and a fork child's main (and only) thread will have a pid equal to its tid, which we get for free from the kernel before clone returns. The only time we'd actually have to make a getpid system call now is if we take a signal during fork and the signal handler calls getpid. (That, or we call getpid in the dynamic linker while it's still dealing with its own relocations and hasn't even set up the main thread yet.)

* AArch64: libm: Fix ARM64 fenv_t and refactor ARM64 libm implementation.Serban Constantinescu2014-06-091-0/+40
| | | | | | | | | | | | | | | | 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.

* Switch to g_ for globals.Elliott Hughes2014-05-141-26/+26
| | | | | | | That's what the Google style guide recommends, and we're starting to get a mix. Change-Id: Ib0c53a890bb5deed5c679e887541a715faea91fc

* Reimplement isinf/isnan/fpclassify.Elliott Hughes2014-04-141-0/+109
| | | | | | | | | | | | | | | | 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.
