* libm: Add hardware sqrt, ceil, floor and trunc for x86 & x86_64James Rose2015-03-0617-12/+660
| | | | | | | | | | | | | | | Add hardware implementations for sqrt, ceil, floor and trunc for x86 and x86_64. These routines, and in particular sqrt are much faster than the BSD C language versions of these functions. Fixed whitespace errors. Revised x86 versions with respect to alignment.

* Fix our <complex.h> support.Elliott Hughes2014-11-064-5/+1072
| | | | | | | | | | | | | | | We build libm with -fvisibility=hidden, so we weren't exporting any of the <complex.h> functions. We also weren't building many of the functions anyway. We were also missing the complex inverse trigonometric functions. And because we didn't even have perfunctory "call each function once" tests, we didn't notice that we weren't exporting any symbols, so this patch adds at least that level of testing.

* Move the meat of <features.h> into <sys/cdefs.h>.Elliott Hughes2014-08-191-1/+0
| | | | | | | | This way it's a lot harder for us to screw up (since we should always be including <sys/cdefs.h> anyway). Bug: 14659579 Change-Id: I23070fff3296b0d1c683bb5e3a6e214146327d53
* Fix <features.h> (_BSD_SOURCE and _GNU_SOURCE).Elliott Hughes2014-08-182-3/+4
| | | | | | | | | | | <features.h> is supposed to take user-settable stuff like _GNU_SOURCE and _BSD_SOURCE and turn them into __USE_GNU and __USE_BSD for use in the C library headers. Instead, bionic used to unconditionally define _BSD_SOURCE and _GNU_SOURCE, and then test _GNU_SOURCE in the header files (which makes no sense whatsoever).

* | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
