* Replace unnecessary x86 uses of <sys/linux-syscalls.h> with <asm/unistd.h>.Elliott Hughes2013-03-214-4/+4

* The SYS_ constants should cover all __NR_ values.Elliott Hughes2013-03-21204-209/+204
| | | | | | | | | | | <sys/linux-syscalls.h> only contains constants for the syscalls we're generating stubs for. We want all the syscalls available on the architecture in question. Keep using <sys/linux-syscalls.h> on ARM for now because the __NR_ARM_set_tls and __NR_ARM_cacheflush values aren't in <asm/unistd.h>. Change-Id: I66683950d87d9b18d6107d0acc0ed238a4496f44

* 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.

| * Replace .S version of x86 crtfiles with .c versionPavel Chupin2012-11-306-330/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces .S versions of x86 crtfiles with .c which are much easier to support. 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.

* | Clean up _BYTE_ORDER definitions for better x86 portability.Elliott Hughes2012-11-271-0/+1
|/ | | | | | | | | | | | We'd manually hacked _BYTE_ORDER into the arm and mips "_types.h" headers, but not into the x86 one. Judging by upstream, _BYTE_ORDER should be in the "endian.h" headers instead, so let's uniformly do that. I've also ironed out some of the other differences between the different architectures' header files too.

* arm: rewrite crtbegin* as C files.Nick Kralevich2012-06-012-0/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite crtbegin.S -> crtbegin.c crtbegin_so.S -> crtbegin_so.c This change allows us to generate PIC code without relying on text relocations. As a consequence of this rewrite, also rewrite __dso_handle.S -> __dso_handle.c __dso_handle_so.S -> __dso_handle_so.c atexit.S -> atexit.c In crtbegin.c _start, place the __PREINIT_ARRAY__, __INIT_ARRAY__, __FINI_ARRAY__, and __CTOR_LIST__ variables onto the stack, instead of passing a pointer to the text section of the binary. This change appears sorta wonky, as I attempted to preserve, as much as possible, the structure of the original assembly. As a result, you have C files including other C files, and other programming uglyness. Result: This change reduces the number of files with text-relocations from 315 to 19 on my Android build.
