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.

Fix x86_64 build, clean up intermediate libraries. The x86_64 build was failing because clone.S had a call to __thread_entry which was being added to a different intermediate .a on the way to making libc.so, and the linker couldn't guarantee statically that such a relocation would be possible. ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC This patch addresses that by ensuring that the caller and callee end up in the same intermediate .a. While I'm here, I've tried to clean up some of the mess that led to this situation too. In particular, this removes libc/private/ from the default include path (except for the DNS code), and splits out the DNS code into its own library (since it's a weird special case of upstream NetBSD code that's diverged so heavily it's unlikely ever to get back in sync). There's more cleanup of the DNS situation possible, but this is definitely a step in the right direction, and it's more than enough to get x86_64 building cleanly.

Clean up the 32-bit kernel support, fix LP64 fcntl declaration. In practice, thanks to all the registers the stubs don't actually change, but it's confusing to have an incorrect declaration. I suspect that fcntl remains broken for aarch64; it happens to work for x86_64 because the first vararg argument gets placed in the right register anyway, but I have no reason to believe that's true for aarch64. This patch adds a unit test, though, so we'll be able to tell when we get as far as running the unit tests. Change-Id: I58dd0054fe99d7d51d04c22781d8965dff1afbf3

Optimize __memset_chk, __memcpy_chk. DO NOT MERGE. This change creates assembler versions of __memcpy_chk/__memset_chk that is implemented in the memcpy/memset assembler code. This change avoids an extra call to memcpy/memset, instead allowing a simple fall through to occur from the chk code into the body of the real implementation. Testing: - Ran the libc_test on __memcpy_chk/__memset_chk on all nexus devices. - Wrote a small test executable that has three calls to __memcpy_chk and three calls to __memset_chk. First call dest_len is length + 1. Second call dest_len is length. Third call dest_len is length - 1. Verified that the first two calls pass, and the third fails. Examined the logcat output on all nexus devices to verify that the fortify error message was sent properly. - I benchmarked the new __memcpy_chk and __memset_chk on all systems. For __memcpy_chk and large copies, the savings is relatively small (about 1%). For small copies, the savings is large on cortex-a15/krait devices (between 5% to 30%). For cortex-a9 and small copies, the speed up is present, but relatively small (about 3% to 5%). For __memset_chk and large copies, the savings is also small (about 1%). However, all processors show larger speed-ups on small copies (about 30% to 100%). Bug: 9293744 Merge from internal master.

For __memcpy_chk and large copies, the savings is relatively small (about 1%). For small copies, the savings is large on cortex-a15/krait devices (between 5% to 30%). For cortex-a9 and small copies, the speed up is present, but relatively small (about 3% to 5%). For __memset_chk and large copies, the savings is also small (about 1%). However, all processors show larger speed-ups on small copies (about 30% to 100%). Bug: 9293744 Merge from internal master.

Move setlocale(3) and the wchar stubs over to .cpp. Also separate out the C++ files so we can use -Werror on them.

Clean up abort. * A dlmalloc usage error shouldn't call abort(3) because we want to cause a SIGSEGV by writing the address dlmalloc didn't like to an address the kernel won't like, so that debuggerd will dump the memory around the address that upset dlmalloc. * Switch to the simpler FreeBSD/NetBSD style of registering stdio cleanup. Hopefully this will let us simplify more of the stdio implementation. * Clear the stdio cleanup handler before we abort because of a dlmalloc corruption error. This fixes the reported bug, where we'd hang inside dlmalloc because the stdio cleanup reentered dlmalloc. Bug: 9301265 Change-Id: Ief31b389455d6876e5a68f0f5429567d37277dbc

libc: Fix alphasort() signature (and implementation). The declaration for alphasort() in <dirent.h> used the deprecated: int alphasort(const void*, const void*); while both Posix and GLibc use instead: int alphasort(const struct dirent** a, const struct dirent** b); See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/alphasort.html This patch does the following: - Update the declaration to match Posix/GLibc - Get rid of the upstream BSD code which isn't compatible with the new signature. - Implement a new trivial alphasort() with the right signature, and ensure that it uses strcoll() instead of strcmp(). - Remove Bionic-specific #ifdef .. #else .. #endif block in dirent_test.cpp which uses alphasort(). Even through strcoll() currently uses strcmp(), this does the right thing in the case where we decide to update strcoll() to properly implement locale-specific ordered comparison.

Add signalfd call to bionic 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.)

<pthread.h> fixes and pthread cleanup. <pthread.h> was missing nonnull attributes, noreturn on pthread_exit, and had incorrect cv qualifiers for several standard functions. I've also marked the non-standard stuff (where I count glibc rather than POSIX as "standard") so we can revisit this cruft for LP64 and try to ensure we're compatible with glibc. I've also broken out the pthread_cond* functions into a new file. I've made the remaining pthread files (plus ptrace) part of the bionic code and fixed all the warnings. I've added a few more smoke tests for chunks of untested pthread functionality. We no longer need the libc_static_common_src_files hack for any of the pthread implementation because we long since stripped out the rest of the armv5 support, and this hack was just to ensure that __get_tls in libc.a went via the kernel if necessary.

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.

Fix x86_64 build, clean up intermediate libraries. The x86_64 build was failing because clone.S had a call to __thread_entry which was being added to a different intermediate .a on the way to making libc.so, and the linker couldn't guarantee statically that such a relocation would be possible. ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC This patch addresses that by ensuring that the caller and callee end up in the same intermediate .a. While I'm here, I've tried to clean up some of the mess that led to this situation too. In particular, this removes libc/private/ from the default include path (except for the DNS code), and splits out the DNS code into its own library (since it's a weird special case of upstream NetBSD code that's diverged so heavily it's unlikely ever to get back in sync). There's more cleanup of the DNS situation possible, but this is definitely a step in the right direction, and it's more than enough to get x86_64 building cleanly.

bionic: allow the board to customize MALLOC_ALIGNMENT Currently the dlmalloc allocates the memory with 8-byte alignment. According to the com.aurorasoftworks.quadrant.ui.professional benchmark data: We can get much better memory performance if we change it to be 16-byte aligned. For example, On Nexus-S: 8-byte aligned : 1378 1070 1142 1665 1765 1163 1179 1263 1404 avg: 1336.555555556 16-byte aligned: 1691 1731 1780 1691 1671 1678 1802 1758 1780 avg: 1731.333333333 gain: 29.53% That patch provides flexibity to customize the MALLOC_ALIGNMENT from the board config.The macro MALLOC_ALIGNMENT defaults to 8.

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.

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.

# AArch64, ARM, MIPS, and x86 all need crtbegin_so/crtend_so.
Allow static C++ destructors to be properly called on dlclose(). With this patch, _and_ an upcoming build/ patch, the destruction of static C++ objects contained in shared libraries will happen properly when dlclose() is called. Note that this change introduces crtbegin_so.S and crtend_so.S which are currently ignored by the build system. + move definition of __dso_handle to the right place (before that, all shared libraries used the __dso_handle global variable from the C library). Note that we keep a 'weak' __dso_handle in aeabi.c to avoid breaking the build until the next patch to build/core/combo/ appears. We will be able to remove that later. + move bionic/aeabi.c to arch-arm/bionic/ (its proper location) Change-Id: Ie771aa204e3acbdf02fd30ebd4150373a1398f39 NOTE: The NDK will need to be modified to enable this feature in the shared libraries that are generated through it.

Fix x86_64 build, clean up intermediate libraries. The x86_64 build was failing because clone.S had a call to __thread_entry which was being added to a different intermediate .a on the way to making libc.so, and the linker couldn't guarantee statically that such a relocation would be possible. ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC This patch addresses that by ensuring that the caller and callee end up in the same intermediate .a. While I'm here, I've tried to clean up some of the mess that led to this situation too. In particular, this removes libc/private/ from the default include path (except for the DNS code), and splits out the DNS code into its own library (since it's a weird special case of upstream NetBSD code that's diverged so heavily it's unlikely ever to get back in sync). There's more cleanup of the DNS situation possible, but this is definitely a step in the right direction, and it's more than enough to get x86_64 building cleanly.

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.) Change-Id: I7db2e386694f6933db043138e6e97e5ae54d4174

Fix x86_64 build, clean up intermediate libraries. The x86_64 build was failing because clone.S had a call to __thread_entry which was being added to a different intermediate .a on the way to making libc.so, and the linker couldn't guarantee statically that such a relocation would be possible. ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC This patch addresses that by ensuring that the caller and callee end up in the same intermediate .a. While I'm here, I've tried to clean up some of the mess that led to this situation too. In particular, this removes libc/private/ from the default include path (except for the DNS code), and splits out the DNS code into its own library (since it's a weird special case of upstream NetBSD code that's diverged so heavily it's unlikely ever to get back in sync). There's more cleanup of the DNS situation possible, but this is definitely a step in the right direction, and it's more than enough to get x86_64 building cleanly.

Split libc_debug.so into two .so modules loaded on demand from libc.so This change is intended to eliminate need to replace libc.so with libc_debug.so in order to enablememory allocation debugging. This is also the first step towards implementing extended memoryallocation debugging using emulator's capabilities in monitoring memory access.

# For all builds, except for the -user build we will enable memory
# allocation checking (including memory leaks, buffer overwrites, etc.)
# Note that all these checks are also controlled by env. settings
# that can enable, or disable specific checks. Note also that some of
# the checks are available only in emulator and are implemeted in
# libc_malloc_qemu_instrumented.so.

libc: Cleanup the libc makefile. Removes a lot of redundant code, and reorganizes the file. We first setup all the comomn variables we may need, and then define the actual libraries that need to be generated. Signed-off-by: Dima Zavin <dima@android.com>

Fix the duplication in the debugging code. We had two copies of the backtrace code, and two copies of the libcorkscrew /proc/pid/maps code. This patch gets us down to one. We also had hacks so we could log in the malloc debugging code. This patch pulls the non-allocating "printf" code out of the dynamic linker so everyone can share. This patch also makes the leak diagnostics easier to read, and makes it possible to paste them directly into the 'stack' tool (by using relative PCs). This patch also fixes the stdio standard stream leak that was causing a leak warning every time tf_daemon ran. Bug: 7291287 Change-Id: I66e4083ac2c5606c8d2737cb45c8ac8a32c7cfe8
