* 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.

* Avoid a system call in 'gettid'.Elliott Hughes2014-06-021-0/+11
| | | | | | | | | | | | | System calls can be pretty slow. This is mako, which has one of our lowest latencies: iterations ns/op BM_unistd_getpid 10000000 209 BM_unistd_gettid 200000000 8 Bug: 15297299 (kernel panic from too many gettid calls) Bug: 15315766 (excessive gettid overhead in liblogd) Change-Id: I49656c0fc5b5d092390264a59e4f2c0d8a8b1aeb

| | | | | | Only affects tests/benchmarks. Confirmed passing on arm. Change-Id: If158e23e8cd06e7597ef6f3c9376f6799b467e62
* 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

* Modify hard-coded directory.Christopher Ferris2014-05-011-2/+12
| | | | | | | Use the ANDROID_DATA environment variable instead of the hard-coded directory for these benchmarks. Change-Id: I00bae7b4a24e81e77fc8f52e1fe99f4d4918f520

* 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.
