* Use arch-specific LOCAL_ variables to build libm.Ying Wang2014-02-031-19/+21
| | | | | | | | Use arch-specific LOCAL_ variables to build libm for both TARGET_ARCH and TARGET_2ND_ARCH. Bug: 11654773 Change-Id: I6da794ba722bb68e7484d8869c6eb0425b7d17cb
* bionic: rename aarch64 target to arm64Colin Cross2014-01-234-3/+3
| | | | | | | Rename aarch64 build targets to arm64. The gcc toolchain is still aarch64. Change-Id: Ia92d8a50824e5329cf00fd6f4f92eae112b7f3a3

* Don't use weak aliases in libm.Elliott Hughes2013-12-182-2/+20
| | | | | | | The aarch64 toolchain doesn't support them, and we were already implementing most of the fake long-double functions differently anyway. Change-Id: I4a2f2df81972ee9c34ddfe96cec81b126506d881

* Switch to upstream sleep(3) and usleep(3).Elliott Hughes2013-11-202-1/+32
| | | | | | | | | | | Also fix the signature of usleep, and the definition of useconds_t which should be unsigned, as the 'u' in its name implies. This patch also cleans up the existing FreeBSD hacks by moving the libm stuff from <sys/cdefs.h> to a libm-private header, and adding comments about the hacks we use to build FreeBSD source.

| | | | | | | | This reverts commit ad59322ae432d11ff36dcf046016af8cfe45fbe4 somehow my unfinished libm/Android.mk change got into here. Change-Id: I46be626c5269d60fb1ced9862f2ebaa380b4e0af
* Pull the pthread_key_t functions out of pthread.c.Elliott Hughes2013-02-111-46/+36
| | | | | | | | | | | | 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

| | | | | | | This doesn't usually matter because there's a weak reference; you'd miss this if you stopped using s_logb.c though. Change-Id: I912fceae327a378031cd24a64aefa9dfd84f7f90

* Upgrade libm.Elliott Hughes2013-02-01282-7946/+7083
| | | | | | | | | | | | | | | | | | | This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies the set of functions we support on ARM, MIPS, and x86, fixes "long double", adds ISO C99 support, and adds basic unit tests. It turns out that our "long double" functions have always been broken for non-normal numbers. This patch fixes that by not using the upstream implementations and just forwarding to the regular "double" implementation instead (since "long double" on Android is just "double" anyway, which is what BSD doesn't support). All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.

* remove obsolete SuperH supportDavid 'Digit' Turner2012-01-311-11/+1
| | | | | | | | | | | | | | | | | | | We don't have a toolchain anymore, we don't have working original kernel headers, and nobody is maintaining this so there is really no point in keeping this here. Details of the patch: - removed code paths from Android.mk files related to the SuperH architecture ("sh") - removed libc/arch-sh, linker/arch-sh, libc/kernel/arch-sh - simplified libc/SYSCALLS.TXT - simplified the scripts in libc/tools/ and libc/kernel/tools Change-Id: I26b0e1422bdc347489e4573e2fbec0e402f75560 Signed-off-by: David 'Digit' Turner <digit@android.com>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sincos() functions would be turned into infinite calls to itself if sincos optimization is applied to itself. See gcc bugzilla http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46926 arm-linux-androideabi-4.4.3 toolchain does not have this problem because sincos optimization is entirely disabled. Starting from arm-linux-androideabi-4.6 toolchain, we enable sincos optimization in gcc. This patch simply enforce -O0 on this function to minimize the change.
