* Fix arm64 fenv warnings, and make warnings errors.Christopher Ferris2015-11-072-4/+16
| | | | | | | | | | | | | Even though the control registers being read/written in fenv.c only have 32 bits that are used, the instructions take a 64 bit register. Make sure the inline assembler in the macros use 64 bit values. Verified that before the change and after the change, the disassembly is exactly the same. In addition, add -Werror to the cflags.

* Revert "Revert "Use compiler builtins for fabs.""Elliott Hughes2015-11-076-68/+60
| | | | | | | | | Don't enable the inlines when building libm itself. Otherwise clang gets upset by seeing both an inline and a non-inline definition. This reverts commit c5deb0f883cbdca7e5ab75f92f82c31d21367f49. Change-Id: If7abdb351f5a5549d6a331b33af408e8fcfa9868

* 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).
