b235f8c877 Merge "Fix dev_t (for LP64)." 2014-01-06 20:37:03 +00:00
Elliott Hughes
338e6102a6 Add TCPOPT_* constants.
Adds the TCPOPT_* constants from NetBSD. Note that the BSDs also have
TCPOPT_SIGNATURE, but Linux calls that TCPOPT_MD5SIG and glibc doesn't
have any corresponding constant yet, so let's wait until we see which name
wins out.

894f8cb139 Fix dev_t (for LP64).
32-bit Android's dev_t was wrong too. We can't fix that without ABI breakage,
but we can at least fix 64-bit Android. And add tests.

c5bf703c4c Remove as many hard-coded constants from the MIPS vfork.S as possible.
We could do better, but not without MIPS cleaning up their kernel headers.

a85aaf11fa Use the MAX_ERRNO constant.
If you're going to hardcode a constant, you could at least try to
get the constant right...

887e1140fe Clean up <sched.h>.
This patch switches to using the uapi constants. It also adds the missing
setns system call, fixes sched_getcpu's error behavior, and fixes the
gensyscalls script now ARM is uapi-only too.

766c7efe28 Allocate additional space on stack for indirect syscall
The caller is only required to allocate 16 bytes on the
stack for a0-a3. syscall is handling up to 6 arguments so
additional space is needed on the stack to avoid corrupting the
callers frame.

e3fb66dd01 Add __popcountsi2 to the function compat list.
This is needed if we use Clang to compile Bionic, which won't include
__popcountsi2 anymore as Clang generates inline instructions. However
prebuilt binary blobs still depend on libc.so to resolve __popcountsi2.

e7c59f9e20 Fix compilation of crtbegin.c and pthread_debug.cpp.
Because there was no default := for the aarch64 libc_crt_target_cflags,
the += was causing libc_crt_target_cflags to be recursively-defined
variable, which meant that when we were compiling crtbegin.c LOCAL_PATH
would be bionic/tests/ and we'd have -Ibionic/tests/include/ and find
none of our include files.

Also fix linking of pthread_debug.cpp, at least in the disabled mode.
The enabled mode was already broken for all architectures, and continues
to be broken after this change. It's been broken for long enough that
we might want to just remove it...

(aarch64 is using the FSF linker where arm uses the gold linker.)

c13fb75cea Move bionic over to GCC's 'warning' attribute.
This is a better solution than the old __warn_references because it's
a compile-time rather than link-time warning, it doesn't rely on something
that doesn't appear to be supported by gold (which is why you only used
to see these warnings on mips builds), and the errors refer to the exact
call site(s) rather than just telling you which object file contains a
reference to the bad function.

This is primarily so we can build bionic for aarch64; building libc.so
caused these warnings to fire (because link time is the wrong time) and
warnings are errors.

e210488e0d AArch64: Add initial support for AArch64
This is the first patch out of a series of patches that add support for
AArch64, the new 64bit execution state of the ARMv8 Architecture. The
patches add support for LP64 programming model.

The patch adds:
* "arch-aarch64" to the architecture directories.
* "arch-aarch64/include" - headers used by libc
* "arch-aarch64/bionic":
    - crtbegin, crtend support;
    - aarch64 specific syscall stubs;
    - setjmp, clone, vfork assembly files.

2b333b97a2 Clean up the pthread-only atomic stuff a little.
It looks like we can probably just use the generic GCC stuff instead;
the generated code looks pretty similar. We should come back to that.

These routines are only used by the pthread implementation, and
__bionic_atomic_inc isn't used, so we can remove it.
