e7ea9363cb Merge "Add ARMv8 optimized string handling functions based on cortex-strings" 2014-03-06 23:02:11 +00:00
Bernhard Rosenkraenzer
7e4fa56099 Add ARMv8 optimized string handling functions based on cortex-strings
This adds ARMv8 optimized string handling functions to Bionic.
The implementations live in a generic/ directory because there will
likely be more CPU specific versions (e.g. Cortex-A53 vs. Cortex-A57)
later.

These implementations are 50%+ faster on current v8 models.

85c5202a64 Fix broken pointer overflow check ns_name_unpack()
Many compilers may optimize away the overflow check `msg + l < msg',
where `msg' is a pointer and `l' is an integer, because pointer
overflow is undefined behavior in C.

Use a safe precondition test `l >= eom - msg' instead.

f0870c3bfe Fix some pthread symbols build as C++ symbol under x64 lunch.
Functions protected with !defined(__LP64__) will be get build as C++
symbols for X64 build. This is not the desired work. So protect the
implementation with !defined(__LP64__) as well.

39b644a0e2 Remove dead NULL checks from pthread code.
GCC is removing these checks anyway because it knows the arguments
must be non-null, so leaving this code around is just confusing.

We know from experience that people were shipping code with locking
bugs because they weren't checking for error returns. Failing hard
like glibc does seems the better choice. (And it's what the checked
in code was already doing; this patch doesn't change that. It just
makes it more obvious that that's what's going on.)

51e6cb33e3 Implement pthread_condattr_{get,set}clock.
We only support CLOCK_REALTIME and CLOCK_MONOTONIC for now,
so we us a single bit from pthread_cond_t->value to denote
the clock type. Note that this reduces the width of the counter
to 30 bits, but this should be large enough for all practical
purposes.

aedb00d04e Switch to upstream alarm(3).
The only way the setitimer call can fail is if the unsigned number of seconds is
too large to fit in the kernel's signed number of seconds. If you schedule a
68-year alarm, glibc will fail by returning 0 and BSD will fail by returning -1.

9bd9b7dd20 If the kernel doesn't have MADV_MERGEABLE, stop asking for it.
Note that a dynamically-linked binary will still probably see two attempts ---
one by the dynamic linker (which will set its copy of the flag so it won't try
again) and then one by the executable itself (which gets a new uninitialized
copy of the flag).

fd3a9fb0c3 Vastly reduce the number of read(2)s done in tzload.
This costs us about 1000 fewer syscalls, which makes "adb shell strace date"
a lot more readable (which is the reason I've been meaning to fix this for a
long time now), but also actually saves a measurable amount of time.

Longer-term we should try to keep the tzdata mmap(2)ed in like libcore
does.

ba76572789 Fix log_backtrace assertion failure caused by LP64 fix.
When libc.debug.malloc is enabled, stack backtraces fail with:

bionic/libc/bionic/libc_logging.cpp:378: assertion "conversion
    specifier unsupported" failed

The cause was a change to the format specifier from "%08x" to
"%0*x" to pass the field width as an additional parameter.
Unfortunately this modifier isn't supported by out_vformat() in
libc_logging.cpp.

Changed to use "%016x" if __LP64__ is defined; "%08x" otherwise.

37e9570bce Fix 64-bit build.
A warning about signed vs unsigned comparison was converted
into an error here :

 ...
 struct stat st;
 if (st.st_size > sizeof(prop_area) {
 ...

st_size is either an off64_t, which is a signed type. It's
worth investigating why this didn't trigger a warning on 32 bit,
where it's signed as well.

851e68a240 Unify our assembler macros.
Our <machine/asm.h> files were modified from upstream, to the extent
that no architecture was actually using the upstream ENTRY or END macros,
assuming that architecture even had such a macro upstream. This patch moves
everyone to the same macros, with just a few tweaks remaining in the
<machine/asm.h> files, which no one should now use directly.

I've removed most of the unused cruft from the <machine/asm.h> files, though
there's still rather a lot in the mips/mips64 ones.

x0 is 0x00000000FFFFFFFF.  When interpreted as a ssize_t that is
INT_MAX, not -1.

Change __set_errno to return long, which will cause x0 to be set instead
of w0.

aa0ebdafc7 Clean up sys_signame and sys_siglist a little.
We don't need quite so much duplication because we already have a way
to get the signal number from its name, and that already copes with the
fact that the mips/mips64 numbers are different from everyone else's.

Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

f25d677147 Reconfig libc's Android.mk to build for multilib
1. Moved arch-specific setup to their own files:
    - <arch>/<arch>.mk, arch-specific configs. Variables in those config
      end with the arch name.
    - removed the extra complexity introduced by function libc-add-cpu-variant-src,
      which seems to be not very useful these days.
2. Separated out the crt object files generation rules and set up the
   rules for both TARGET_ARCH and TARGET_2ND_ARCH.
3. Build all the libraries for both TARGET_ARCH and TARGET_2ND_ARCH,
  with the arch-specific LOCAL_ variables.

199346a2ab Fix NSIG.
Our sigset_t definition hasn't been tied to our NSIG definition since we
switched to uapi headers, so we can now fix it without breaking the LP32 ABI.
The kernel uapi headers define and use _NSIG, so we need to have our scripts
rename the kernel's definitions out of the way, then we can define _NSIG
and NSIG in terms of the kernel's off-by-one value.

We don't actually need to worry about sign extension if we reject

in the case of mmap (as opposed to mmap64) we'd incorrectly turn
those into large positive offsets.

Vadim Markovtsev
323d4b6f68 Add "__noreturn" to assert and assert2
These functions should print assertion violation messages and then
call abort(). They do really not return control flow afterwards.
Consider the declaration of the similar __assert_fail from glibc:

extern void __assert_fail (const char *__assertion,
                           const char *__file,
			   unsigned int __line,
                           const char *__function)
     __THROW __attribute__ ((__noreturn__));

Bionic has __noreturn defined in sys/cdefs.h to be that GNU
noreturn attribute.

This patch has a practical value. Consider the following function:

void check(void* ptr) {
  assert(ptr != NULL);
}

Without this patch applied, gcc (and presumably clang) shows even in
debug mode:

warning: unused parameter 'ptr' [-Wunused-parameter]

In release mode, NDEBUG is defined and assert() becomes a no-op, as
one should expect. Thus, the warning is shown correctly then.

Another code sample:

float array[2];
int i = 3;
...
assert(i < 2);
array[i] = 0;

gcc says,

warning: array subscript is below array bounds [-Warray-bounds]

In other words, without noreturn attribute, assertions do not
allow a compiler's static analyzer to properly understand
the preconditions.

0f461e35f6 Fix <sys/resource.h>.
The situation here is a bit confusing. On 64-bit, rlimit and rlimit64 are
the same, and so getrlimit/getrlimit64, setrlimit/setrlimit64,
and prlimit/prlimit64 are all the same. On 32-bit, rlimit and rlimit64 are
different. 32-bit architectures other than MIPS go one step further by having
an even more limited getrlimit system call, so arm and x86 need to use
ugetrlimit instead of getrlimit. Worse, the 32-bit architectures don't have
64-bit getrlimit- and setrlimit-equivalent system calls, and you have to use
prlimit64 instead. There's no 32-bit prlimit system call, so there's no
easy implementation of that --- what should we do if the result of prlimit64
won't fit in a struct rlimit? Since 32-bit survived without prlimit/prlimit64
for this long, I'm not going to bother implementing prlimit for 32-bit.

We need the rlimit64 functions to be able to build strace 4.8 out of the box.

since that would seem less likely to cause trouble, but glibc
source compatibility is probably more important.

Also standardize the orthography in a few places to reduce near-duplicates
in the NOTICE files.

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.
