Elliott Hughes
8794ece296 Replace unnecessary ARM uses of <sys/linux-syscalls.h> with <asm/unistd.h>.
For some reason, socketcalls.c was only being compiled for ARM, where
it makes no sense. For x86 we generate stubs for the socket functions
that use __NR_socketcall directly.

Elliott Hughes
5c2772f59d The SYS_ constants should cover all __NR_ values.
<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>.

are supported using #ifdef of the appropriate SYS_ constant.

86c3184972 Merge "Create arch specific versions of strcmp." 2013-03-20 22:14:48 +00:00
Christopher Ferris
31dea25b8b Create arch specific versions of strcmp.
This uses the new strcmp.a15.S code as the basis for new versions
of strcmp.S.

The cortex-a15 code is the performance optimized version of strcmp.a15.S
taken with only the addition of a few pld instructions.
The cortex-a9 code is the same as the cortex-a15 code except that the
unaligned strcmp code was taken from the original strcmp.S.
The krait code is the same as the cortex-a15 code except that one path
in the unaligned strcmp code was taken from the original strcmp.S code
(the 2 byte overlap case).
The generic code is the original unmodified strmp.S from the bionic
subdirectory.

All three new versions underwent these test cases:

Strings the same, all same size:
- Both pointers double word aligned.
- One pointer double word aligned, one pointer word aligned.
- Both pointers word aligned.
- One pointer double word aligned, one pointer 1 off a word alignment.
- One pointer double word aligned, one pointer 2 off a word alignment.
- One pointer double word aligned, one pointer 3 off a word alignment.
- One pointer word aligned, one pointer 1 off a word alignment.
- One pointer word aligned, one pointer 2 off a word alignment.
- One pointer word aligned, one pointer 3 off a word alignment.
For all cases where it made sense, the two pointers were also tested
swapped.

Different strings, all same size:
- Single difference at double word boundary.
- Single difference at word boudary.
- Single difference at 1 off a word alignment.
- Single difference at 2 off a word alignment.
- Single difference at 3 off a word alignment.

Different sized strings, strings the same until the end:
- Shorter string ends on a double word boundary.
- Shorter string ends on word boundary.
- Shorter string ends at 1 off a word boundary.
- Shorter string ends at 2 off a word boundary.
- Shorter string ends at 3 off a word boundary.

For all different cases, run them through the same pointer alignment
cases when the strings are the same size.
For all cases the two pointers were also tested swapped.

8f2a5a0b40 Clean up internal libc logging.
We only need one logging API, and I prefer the one that does no
allocation and is thus safe to use in any context.

Also use O_CLOEXEC when opening the /dev/log files.

Move everything logging-related into one header file.

306a353825 Remove unused arm defines.
The defines HAVE_32_BYTE_CACHE_LINES and ARCH_ARM_USE_NON_NEON_MEMCPY
are not used by any code. The previous memcpy code that used these
has been split into different architecture versions to avoid the need
for them.

Elliott Hughes
e0175ca7e4 Don't search off the end of the index for bad Olson ids.
In the old code, the index was a file to itself, so it made sense to
read until you hit the end of the file. In the new code, the index is
followed by hundreds of KiB of data, so we need to just search the
index.

ca0c11bd82 Use more types than just 'unsigned' in the linker.
Still chipping away at the situation where every variable in the
linker was of type 'unsigned'. This patch switches counts over to
being size_t and adds an explicit type for init/fini function pointers
and arrays of function pointers.

Also improve logging from CallArray.

Also remove trailing "\n"s from log messages.

Elliott Hughes
4a05bef4c0 Cache the most-recently used timezone for mktime_tz and localtime_tz.
Normally, the C library implicitly caches your timezone by virtue
of the fact that the prehistoric API assumes a single timezone for
the entire process.

The unfortunate mktime_tz and localtime_tz extensions work around
this, but represent timezones as strings to their callers, so code
that makes heavy use of these needs a cache to be able to perform
acceptably until it can hopefully one day be rewritten to use
java.util.Calendar or icu4c.

From the release notes:

  Changes affecting current and future time stamps:

    Haiti uses US daylight-saving rules this year, and presumably future years.
    This changes time stamps starting today.  (Thanks to Steffen Thorsen.)

    Paraguay will end DST on March 24 this year.
    (Thanks to Steffen Thorsen.)  For now, assume it's just this year.

    Morocco does not observe DST during Ramadan;
    try to predict Ramadan in Morocco as best we can.
    (Thanks to Erik Homoet for the heads-up.)
