* Clean up the sigprocmask/pthread_sigmask implementation.Elliott Hughes2013-10-152-28/+0
| | | | | | | | | | | Let's have both use rt_sigprocmask, like in glibc. The 64-bit ABIs can share the same code as the 32-bit ABIs. Also, let's test the return side of these calls, not just the setting. Bug: 11069919 Change-Id: I11da99f85b5b481870943c520d05ec929b15eddb

* Fix __errno for LP64 and clean up __get_tls.Elliott Hughes2013-10-092-38/+0
| | | | | | | | | | | If __get_tls has the right type, a lot of confusing casting can disappear. It was probably a mistake that __get_tls was exposed as a function for mips and x86 (but not arm), so let's (a) ensure that the __get_tls function always matches the macro, (b) that we have the function for arm too, and (c) that we don't have the function for any 64-bit architecture.

* Add arch-x86_64/include/machine.Elliott Hughes2013-10-041-6/+0
| | | | | | | | | | | | | This is basically the other half of I5de76f6c46ac87779f207d568a86bb453e2414de from Pavel Chupin <pavel.v.chupin@intel.com>, but taking the exact upstream _types.h instead of the modified version. (I was confused when I suggested otherwise.) I've also cleaned up the internal_types.h situation; we weren't gaining anything from these empty files, and there is no upstream internal_types.h for x86_64.

* Remove useless x86 fallbacks.Elliott Hughes2013-10-034-139/+1
| | | | | | | | | | | The NDK ABI requires that you support SSE2, and the build system won't let you build with ARCH_X86_HAVE_SSE2 set to false. So let's stop pretending this constant is actually a variable, and let's remove the corresponding dead code. Also, the USE_SSE2 and USE_SSE3 macros are unused, so let's not bother setting them.

* Regenerate the system call stubs (to get x86_64).Elliott Hughes2013-10-01210-210/+210
| | | | | | | | This touches the x86 stubs too because arm, x86, and x86_64 now all share the same header (at a source level), which causes a reordering of the #include lines. Change-Id: If9a1e2b2718bd41d8399fea748bce672c513ef84

* Upgrade libm.Elliott Hughes2013-02-011-0/+2
| | | | | | | | | | | | | | | | | | | 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.

* Add signalfd call to bionicRom Lemarchand2013-01-102-0/+33
| | | | | | | | | | | | | | | | | | | Add signalfd() call to bionic. Adding the signalfd call was done in 3 steps: - add signalfd4 system call (function name and syscall number) to libc/SYSCALLS.TXT - generate all necessary headers by calling libc/tools/gensyscalls.py. This patch is adding the generated files since the build system does not call gensyscalls.py. - create the signalfd wrapper in signalfd.cpp and add the function prototype to sys/signalfd.h (cherry-pick of 0c11611c11f4dc1b6d43587b72c3ccbe8c51a51c, modified to work with older versions of GCC still in use on some branches.)

* Fix <endian.h> and <sys/endian.h>.Elliott Hughes2012-12-111-0/+0
| | | | | | | | | | | Previously we'd been relying on getting the machine-specific <endian.h> instead of the top-level <endian.h>, and <sys/endian.h> was basically broken. Now, with this patch and the previous patch we should have <endian.h> and <sys/endian.h> behaving the same. This is basically how NetBSD's endian.h works, and was probably how ours was originally intended to work.

Some of the files are matching .c version of Arm crtfiles. x86 files required some cleanup anyway and this cleanup actually led to matching Arm files. I didn't change anything to share the same crt*.c between x86 and Arm. I prefer to keep them separate for a while in case any change is required for one of the arch, but it's good thing to do in the following patches.
