* Fix GNU/POSIX basename headers.Josh Gao2016-03-092-10/+11
| | | | | | | | | | Including glibc's <libgen.h> will result in the user getting the POSIX version of basename always, regardless of when it is included relative to <string.h>. Prior to this patch, our implementation would result in the one that's included first winning. Bug: http://b/25459151 Change-Id: Id4aaf1670dad317d6bbc05763a84ee87596e8e59

* Fix regoff_t for LP32 and _FILE_OFFSET_BITS=64.Elliott Hughes2015-11-071-2/+3
| | | | | | | | | | bionic is built without _FILE_OFFSET_BITS=64, so internally regoff_t was 32-bit on LP32, but code compiled with _FILE_OFFSET_BITS would expect rm_so and rm_eo in struct regmatch_t to be 64-bit, leading to confusion.

* Avoid name collision with user_fpsimd_state in <asm/ptrace.h>.Elliott Hughes2015-06-151-2/+2
| | | | | | | | | | | | | We don't want to use <asm/ptrace.h> because (a) it'll drag in a bunch of namespace pollution and (b) the registers should be "long double" for userspace, not the kernel's uint128s. So just use a slightly different name for our struct (which matches the traditional names for these structs anyway).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was already present for the other architectures. I think we skipped this because glibc seems to have an incorrect definition (int rather than long), but the kernel has the sane definition (just not in a uapi header).

The #define is to keep chromium off our lawn; otherwise it tries to redefine all this stuff itself. We should probably clean that up and remove the #define.

| | * Add in_port_t and move it and in_addr_t to the correct header file.Elliott Hughes2014-10-292-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No one's reported this, but I saw it in an Android port of fuser(1). We still have lots of problems in our network headers because we get most of the structs direct from the kernel, and it doesn't use types like this (which is why we've got away without this one for so long). One day we should probably look at cleaning that up, but doing so can wait.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __open_2() is used by the fortify implementation of open(2) in fcntl.h, and as such needs an unmangled C name. For some reason (inlining?), this doesn't cause problems at the default optimization level, but does for -O0. The rest of these didn't cause build failures, but they look suspect and probably will, we just haven't caught them yet.

| | * Add pthread_gettid_np and re-expose __get_thread for LP32.Elliott Hughes2014-09-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of third-party code calls the private __get_thread symbol, often as part of a backport of bionic's pthread_rwlock implementation. Hopefully this will go away for LP64 (since you're guaranteed the real implementation there), but there are still APIs that take a tid and no way to convert between a pthread_t and a tid. pthread_gettid_np is a public API for that. To aid the transition, make __get_thread available again for LP32. Bug: 14079438 Change-Id: I43fabc7f1918250d31d4665ffa4ca352d0dbeac1

It makes the preexisting code that uses __sync implementations much more useful, although we should no longer be exercising that code in AOSP. Specifically fixes: We were invoking __has_extension and __has_builtin for GCC compilations. They're clang specific. Restructured the tests. The __sync implementation was not defining the LOCK_FREE macros. ATOMIC_VAR_INIT was using named field initializations. These are a C, not C++, feature, that is not supported by g++ 4.6. The stdatomic bionic test still failed with 4.6 and glibc with our questionable LOCK_FREE macro implementation. Don't run that piece with 4.6. In L, this is a prerequisite for fixing: Bug:16880454 Bug:16513433 Change-Id: I9b61e42307f96a114dce7552b6ead4ad1c544eab (cherry picked from commit 32429606bf696d3b2ca555f132a0d60c566d0bd0)

This generalizes the bionic header so that it can be used directly as the prebuilt header as well. So long as they don't diverge again, that should somewhat improve test coverage. Use the correct builtin for atomic_is_lock_free. Fix atomic_flag_init. Turn on atomic tests even with __GLIBC__, since they now appear to pass. Include uchar.h in stdatomic.h where needed.

| | * Use __GNUC_PREREQ rather than __GNUC_PREREQ__ to match glibc.Elliott Hughes2014-08-292-20/+20

| | * Expose android_set_abort_message().Dan Albert2014-08-191-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | Removes the leading underscores from __android_set_abort_message() and moves its declaration into a public header file. Bug: 17059126 Change-Id: I470c79db47ec783ea7a54b800f8b78ecbe7479ab (cherry picked from commit ce6b1abbb1da797e716d8ec03da4e3b6304fd11d) (cherry picked from commit 3a25ab952befbe908f6df45805683ebe3bf65863)
| | * Have stdatomic.h punt to C++ atomic when possibleHans Boehm2014-08-151-0/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an alternate, somewhat simpler, fix that makes it safe to include both <atomic> and <stdatomic.h> from C++ code in either order. It means that C code consistently uses one implementation of atomics and C++ another. We still have to make sure that those two implementations interoperate correctly at runtime; in particular, any flavor of atomic object needs to be represented exactly like the underlying type, with the proper alignment constraint.

| | * Change name of MB_CUR_MAX implementation function.Dan Albert2014-08-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Glibc calls theirs __ctype_get_mb_cur_max. Make ours match to cut down on differences between bionic and glibc. Bug: 11156955 Change-Id: Ib7231f01aa9676dff30aea0af25d597bfe07bc73
| | * Proper MB_CUR_MAX.Dan Albert2014-08-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously this was hard coded to 4. This is only the case for UTF-8 locales. As a side effect, this properly reports C.UTF-8 as the default locale instead of C.
