* Fix arm64 fenv warnings, and make warnings errors.Christopher Ferris2015-11-071-0/+1
| | | | | | | | | | | | | 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 Hughes2015-11-071-3/+5
| | | | | | | | | 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 Rose2015-03-061-12/+40
| | | | | | | | | | | | | | | 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 Hughes2014-11-061-5/+14
| | | | | | | | | | | | | | | 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.

* | Fix <math.h> to quieten most of our warnings.Elliott Hughes2014-05-051-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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
