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.

# Make everything depend on any changes to included makefiles.
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. Bug: 11654773 Change-Id: I9c2d85db0affa49199d182236d2210060a321421

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. Change-Id: I6dc411a3d73589383c85d3b07d9d648311492a10

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.

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.

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.

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. Change-Id: I6dc411a3d73589383c85d3b07d9d648311492a10

Fix __errno for LP64 and clean up __get_tls. If __get_tls has the right type, a lot of confusing casting can disappear. It was probably a mistake that __get_tls was exposed as a function for mips and x86 (but not arm), so let's (a) ensure that the __get_tls function always matches the macro, (b) that we have the function for arm too, and (c) that we don't have the function for any 64-bit architecture.

Fix "faccessat ignores flags" The kernel system call faccessat() does not have any flags arguments, so passing flags to the kernel is currently ignored. Fix the kernel system call so that no flags argument is passed in. Ensure that we don't support AT_SYMLINK_NOFOLLOW. This non-POSIX (http://pubs.opengroup.org/onlinepubs/9699919799/functions/access.html) flag is a glibc extension, and has non-intuitive, error prone behavior. For example, consider the following code: symlink("foo.is.dangling", "foo"); if (faccessat(AT_FDCWD, "foo", R_OK, AT_SYMLINK_NOFOLLOW) == 0) { int fd = openat(AT_FDCWD, "foo", O_RDONLY | O_NOFOLLOW); } The faccessat() call in glibc will return true, but an attempt to open the dangling symlink will end up failing. GLIBC documents this as returning the access mode of the symlink itself, which will always return true for any symlink on Linux. Some further discussions of this are at: * http://lists.landley.net/pipermail/toybox-landley.net/2014-September/003617.html * http://permalink.gmane.org/gmane.linux.lib.musl.general/6952 AT_SYMLINK_NOFOLLOW seems broken by design. I suspect this is why this function was never added to POSIX. (note that "access" is pretty much broken by design too, since it introduces a race condition between check and action). We shouldn't support this until it's clearly documented by POSIX or we can have it produce intuitive results. Don't support AT_EACCESS for now. Implementing it is complicated, and pretty much useless on Android, since we don't have setuid binaries. See http://git.musl-libc.org/cgit/musl/commit/?id=0a05eace163cee9b08571d2ff9d90f5e82d9c228 for how an implementation might look. Bug: 18867827 Change-Id: I25b86c5020f3152ffa3ac3047f6c4152908d0e04

bionic/faccessat.cpp \
Add fchmodat(AT_SYMLINK_NOFOLLOW) and fchmod O_PATH support Many libc functions have an option to not follow symbolic links. This is useful to avoid security sensitive code from inadvertantly following attacker supplied symlinks and taking inappropriate action on files it shouldn't. For example, open() has O_NOFOLLOW, chown() has lchown(), stat() has lstat(), etc. There is no such equivalent function for chmod(), such as lchmod(). To address this, POSIX introduced fchmodat(AT_SYMLINK_NOFOLLOW), which is intended to provide a way to perform a chmod operation which doesn't follow symlinks. Currently, the Linux kernel doesn't implement AT_SYMLINK_NOFOLLOW. In GLIBC, attempting to use the AT_SYMLINK_NOFOLLOW flag causes fchmodat to return ENOTSUP. Details are in "man fchmodat". Bionic currently differs from GLIBC in that AT_SYMLINK_NOFOLLOW is silently ignored and treated as if the flag wasn't present. This patch provides a userspace implementation of AT_SYMLINK_NOFOLLOW for bionic. Using open(O_PATH | O_NOFOLLOW), we can provide a way to atomically change the permissions on files without worrying about race conditions. As part of this change, we add support for fchmod on O_PATH file descriptors, because it's relatively straight forward and could be useful in the future. The basic idea behind this implementation comes from https://sourceware.org/bugzilla/show_bug.cgi?id=14578 , specifically comment #10. Change-Id: I1eba0cdb2c509d9193ceecf28f13118188a3cfa7

Cache getpid. In practice, with this implementation we never need to make a system call. We get the main thread's tid (which is the same as our pid) back from the set_tid_address system call we have to make during initialization. A new pthread will have the same pid as its parent, and a fork child's main (and only) thread will have a pid equal to its tid, which we get for free from the kernel before clone returns. The only time we'd actually have to make a getpid system call now is if we take a signal during fork and the signal handler calls getpid. (That, or we call getpid in the dynamic linker while it's still dealing with its own relocations and hasn't even set up the main thread yet.)

<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.

bionic/wchar.cpp \
Switch to a working UTF-8 mb/wc implementation. Although glibc gets by with an 8-byte mbstate_t, OpenBSD uses 12 bytes (of the 128 bytes it reserves!). We can actually implement UTF-8 encoding/decoding with a 0-byte mbstate_t which means we can make things work on LP32 too, as long as we accept the limitation that the caller needs to present us with a complete sequence before we'll process it. Our behavior is fine when going from characters to bytes; we just update the source wchar_t** to say how far through the input we got. I'll come back and use the 4 bytes we do have to cope with byte sequences split across multiple input buffers. The fact that we don't support UTF-8 sequences longer than 4 bytes plus the fact that the first byte of a UTF-8 sequence encodes the length means we shouldn't need the other fields OpenBSD used (at the cost of some recomputation in cases where a sequence is split across buffers). This patch also makes the minimal changes necessary to setlocale(3) to make us behave like glibc when an app requests UTF-8. (The difference being that our "C" locale is the same as our "C.UTF-8" locale.) Change-Id: Ied327a8c4643744b3611bf6bb005a9b389ba4c2f

upstream-openbsd/lib/libc/locale/wctob.c \
Switch to a working UTF-8 mb/wc implementation. Although glibc gets by with an 8-byte mbstate_t, OpenBSD uses 12 bytes (of the 128 bytes it reserves!). We can actually implement UTF-8 encoding/decoding with a 0-byte mbstate_t which means we can make things work on LP32 too, as long as we accept the limitation that the caller needs to present us with a complete sequence before we'll process it. Our behavior is fine when going from characters to bytes; we just update the source wchar_t** to say how far through the input we got. I'll come back and use the 4 bytes we do have to cope with byte sequences split across multiple input buffers. The fact that we don't support UTF-8 sequences longer than 4 bytes plus the fact that the first byte of a UTF-8 sequence encodes the length means we shouldn't need the other fields OpenBSD used (at the cost of some recomputation in cases where a sequence is split across buffers). This patch also makes the minimal changes necessary to setlocale(3) to make us behave like glibc when an app requests UTF-8. (The difference being that our "C" locale is the same as our "C.UTF-8" locale.) Change-Id: Ied327a8c4643744b3611bf6bb005a9b389ba4c2f

Almost all of our stdio is actually OpenBSD, so although this isn't really a core part of stdio (it doesn't touch struct FILE, for example) it probably makes sense for it to come from the same upstream. My actual motivation though is that it's the only FreeBSD file we have compiler warnings from. This patch moves us over to -Werror by default, with only the DNS code having -Wno-error.

Implement twalk(3), add unit tests. I've also added insque(3) and remque(3) (from NetBSD because the OpenBSD ones are currently broken for non-circular lists). I've not added the three hash table functions that should be in this header because they operate on a single global hash table and thus aren't likely to be useful.

Do not include libc_common in malloc debug code. The inclusion of the static libc_common library in the malloc_debug_XXX.so shared libraries causes constructors to be called twice. This doesn't seem to have caused any issues when setting the libc.debug.malloc property. However, jemalloc crashes because there are two jemalloc implementations, one in the static libc_common library and one in the shared library. Each implementation has created overlapping thread keys that are not the same. The crash comes because one of the jemalloc keys is actually used by the locale setting code. Thus if someone sets the locale, the jemalloc code crashes trying to access the same key. Change-Id: Iaac650a82d69064db148a6333e9403744f68b4a4

Switch to upstream OpenBSD mktemp.c. Almost all of our stdio is actually OpenBSD, so although this isn't really a core part of stdio (it doesn't touch struct FILE, for example) it probably makes sense for it to come from the same upstream. My actual motivation though is that it's the only FreeBSD file we have compiler warnings from. This patch moves us over to -Werror by default, with only the DNS code having -Wno-error.

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.

Almost all of our stdio is actually OpenBSD, so although this isn't really a core part of stdio (it doesn't touch struct FILE, for example) it probably makes sense for it to come from the same upstream. My actual motivation though is that it's the only FreeBSD file we have compiler warnings from. This patch moves us over to -Werror by default, with only the DNS code having -Wno-error.

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. Bug: 11654773 Change-Id: I9c2d85db0affa49199d182236d2210060a321421

Fix <math.h> to quieten most of our warnings. I've reported the wcsftime bug upstream, but we really just want to use -D to ensure the buggy code isn't built. (I've also brought our strftime a bit closer to upstream now we have the right define.) I don't think upstream is likely to fix all their sign-compare and uninitialized warnings, so let's just silence them. As for libm, again upstream isn't likely to fix all their warnings, and silencing those made the ones that were our fault stand out. I've fixed our <math.h> to fix the warnings caused by our lack of definitions for the non-imprecise long-double functions. I checked the C99 standard, and all these functions are there.

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 <math.h> to quieten most of our warnings. I've reported the wcsftime bug upstream, but we really just want to use -D to ensure the buggy code isn't built. (I've also brought our strftime a bit closer to upstream now we have the right define.) I don't think upstream is likely to fix all their sign-compare and uninitialized warnings, so let's just silence them. As for libm, again upstream isn't likely to fix all their warnings, and silencing those made the ones that were our fault stand out. I've fixed our <math.h> to fix the warnings caused by our lack of definitions for the non-imprecise long-double functions. I checked the C99 standard, and all these functions are there.

The replacement new failures present in newer versions are present here as well, with the following new issues: XPASS std/localization/locale.categories/category.numeric/locale.nm.put/facet.num.put.members/put_long_double.pass.cpp This is from the -NaN formatting fix in bionic. We previously had this wrong, and the upstream test is also wrong. There's currently an XFAIL for Android in this test because I haven't fixed the upstream test yet. After that is done, I'll need to teach the test runner how to XFAIL older Android versions... FAIL std/localization/locale.categories/category.ctype/facet.ctype.special/facet.ctype.char.dtor/dtor.pass.cpp dtor.pass.cpp:39: int main(): assertion "globalMemCounter.checkDeleteArrayCalledEq(1)" failed Haven't investigated this one yet. http://b/19412688 Note that this also needs the libgcc link ordering to be fixed in the build system, as we'll otherwise depend on libgcc symbols from libc that may or may not have been there. The build fix can't be submitted because the proper link order causes the libgcc unwinder to be used instead of the EHABI one: http://b/18471342 Bug: 18471532 Change-Id: Icf560485a9b8f5ebbe01e4458703e62ec94df5e1

Fix <math.h> to quieten most of our warnings. I've reported the wcsftime bug upstream, but we really just want to use -D to ensure the buggy code isn't built. (I've also brought our strftime a bit closer to upstream now we have the right define.) I don't think upstream is likely to fix all their sign-compare and uninitialized warnings, so let's just silence them. As for libm, again upstream isn't likely to fix all their warnings, and silencing those made the ones that were our fault stand out. I've fixed our <math.h> to fix the warnings caused by our lack of definitions for the non-imprecise long-double functions. I checked the C99 standard, and all these functions are there.

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

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. Bug: 11654773 Change-Id: I9c2d85db0affa49199d182236d2210060a321421

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 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.

We previously had this wrong, and the upstream test is also wrong. There's currently an XFAIL for Android in this test because I haven't fixed the upstream test yet. After that is done, I'll need to teach the test runner how to XFAIL older Android versions... FAIL std/localization/locale.categories/category.ctype/facet.ctype.special/facet.ctype.char.dtor/dtor.pass.cpp dtor.pass.cpp:39: int main(): assertion "globalMemCounter.checkDeleteArrayCalledEq(1)" failed Haven't investigated this one yet. http://b/19412688 Note that this also needs the libgcc link ordering to be fixed in the build system, as we'll otherwise depend on libgcc symbols from libc that may or may not have been there. The build fix can't be submitted because the proper link order causes the libgcc unwinder to be used instead of the EHABI one: http://b/18471342 Bug: 18471532 Change-Id: Icf560485a9b8f5ebbe01e4458703e62ec94df5e1

Switch to upstream OpenBSD mktemp.c. Almost all of our stdio is actually OpenBSD, so although this isn't really a core part of stdio (it doesn't touch struct FILE, for example) it probably makes sense for it to come from the same upstream. My actual motivation though is that it's the only FreeBSD file we have compiler warnings from. This patch moves us over to -Werror by default, with only the DNS code having -Wno-error.

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

Use libunwindbacktrace for debug malloc code. Create a method of disabling the debug allocation code paths so that it's possible to use the libunwindbacktrace library without any modifications. Use this path to create and destroy the maps for the process. It's not stricly necessary in the init code since the symbols are not modified until after the initialize calls. Also, remove the debug_XXX source files that doesn't need to be in libc.so. Fix the maps reading code since it was completely broken for 64 bit.

Do not include libc_common in malloc debug code. The inclusion of the static libc_common library in the malloc_debug_XXX.so shared libraries causes constructors to be called twice. This doesn't seem to have caused any issues when setting the libc.debug.malloc property. However, jemalloc crashes because there are two jemalloc implementations, one in the static libc_common library and one in the shared library. Each implementation has created overlapping thread keys that are not the same. The crash comes because one of the jemalloc keys is actually used by the locale setting code. Thus if someone sets the locale, the jemalloc code crashes trying to access the same key. Change-Id: Iaac650a82d69064db148a6333e9403744f68b4a4

Never use ASAN. Unless we completely redo how we build bionic (so that the object files for libc.so get built separately from libc.a), we can't enable ASAN here, as libc.a gets linked into static executables. Change-Id: I2ce4f51248bd51c4213a555ff481b6faabbf53f8

include $(BUILD_STATIC_LIBRARY)
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.
