- Android NDK, Revision 8b (July 2012)
+
+
+
+-
+
- Important changes: -
-
+
-
+
- Added the Clang 3.1 compiler to the NDK. The GNU Compiler Collection (GCC) 4.6 is
+ still the default, so you must explicitly enable the Clang compiler option as follows:
+
-
+
- For {@code ndk-build}, export {@code NDK_TOOLCHAIN_VERSION=clang3.1} or + add this environment variable setting to {@code Application.mk}. +
- For standalone builds, add {@code --llvm-version=3.1} to + {@code make-standalone-toolchain.sh} and replace {@code CC} and {@code CXX} in your + makefile with {@code <tool-path>/bin/clang} and + {@code <tool-path>/bin/clang++}. See {@code STANDALONE-TOOLCHAIN.html} for + details. +
Note: This feature is experimental. Please try it and + report any issues.
+ - Added Gold linker {@code ld.gold} for the Windows toolchain. Gold linker is also the + default for ARM and X86 on all hosts. You may override it to use the {@code ld.bfd} + linker by adding {@code LOCAL_LDFLAGS += -fuse-ld=bfd} to {@code Android.mk}, or by passing + {@code -fuse-ld=bfd} to the g++/clang++ command line that does the linking. +
- Added checks for spaces in the NDK path to the {@code ndk-build[.cmd]} and + {@code ndk-gdb} scripts, to prevent build errors that are difficult to diagnose. +
- Made the following changes to API level handling:
+
-
+
- Modified build logic so that projects that specify {@code android-10} through + {@code android-13} in {@code APP_PLATFORM}, {@code project.properties} or + {@code default.properties} link against {@code android-9} instead of + {@code android-14}. +
- Updated build so that executables using android-16 (Jelly Bean) or higher are
+ compiled with the {@code -fPIE} option for position-independent executables (PIE).
+ A new {@code APP_PIE} option allows you to control this behavior. See {@code
+ APPLICATION-MK.html} for details.
+
+ Note: All API levels above 14 still link against {@code + platforms/android-14} and no new {@code platforms/android-N} have been added. +
+ - Modified {@code ndk-build} to provide warnings if the adjusted API level is larger + than {@code android:minSdkVersion} in the project's {@code AndroidManifest.xml}. +
+ - Updated the {@code cpu-features} helper library to include more ARM-specific features. + See {@code sources/android/cpufeatures/cpu-features.h} for details. +
- Modified the long double on the X86 platform to be 8 bytes. This data type is now the + same size as a double, but is still treated as a distinct type. +
- Updated build for {@code APP_ABI=armeabi-v7a}:
+
-
+
- Modified this build type to pass the {@code -march=armv7-a} parameter + to the linker. This change ensures that v7-specific libraries and {@code crt*.o} are + linked correctly. +
- Added {@code -mfpu=vfpv3-d16} to {@code ndk-build} instead of the + {@code -mfpu=vfp} option used in previous releases. +
+
+
+
+ - Added the Clang 3.1 compiler to the NDK. The GNU Compiler Collection (GCC) 4.6 is
+ still the default, so you must explicitly enable the Clang compiler option as follows:
+
- Important bug fixes: + +
-
+
-
+
- Fixed an issue where running {@code make-standalone-toolchain.sh} with root privileges
+ resulted in the stand alone tool chain being inaccessible to some users.
+ (Issue 35279)
+
-
+
- All files and executables in the NDK release package are set to have read and + execute permissions for all. +
- The ownership/group of {@code libstdc++.a} is now preserved when copied. +
+ - Removed redundant {@code \r} from Windows prebuilt {@code echo.exe}. The redundant + {@code \r} caused {@code gdb.setup} to fail in the GNU Debugger (GDB) because it + incorrectly became part of the path. + (Issue 36054) +
- Fixed Windows parallel builds that sometimes failed due to timing issues in the + {@code host-mkdir} implementation. + (Issue 25875) +
- Fixed GCC 4.4.3 GNU {@code libstdc++} to not merge {@code typeinfo} names by + default. For more details, see + {@code toolchain repo gcc/gcc-4.4.3/libstdc++-v3/libsupc++/typeinfo}. + (Issue 22165) +
- Fixed problem on {@code null} context in GCC 4.6 + {@code cp/mangle.c::write_unscoped_name}, where GCC may crash when the context is + {@code null} and dereferenced in {@code TREE_CODE}. +
- Fixed GCC 4.4.3 crashes on ARM NEON-specific type definitions for floats. + (Issue 34613) +
- Fixed the {@code STLport} internal {@code _IteWrapper::operator*()} implementation + where a stale stack location holding the dereferenced value was returned and caused + runtime crashes. + (Issue 38630) + +
- ARM-specific fixes:
+
-
+
- Fixed ARM GCC 4.4.3/4.6 {@code g++} to not warn that the mangling of + <va_list> was changed in GCC 4.4. The workaround using the + {@code -Wno-psabi} switch to avoid this warning is no longer required. +
- Fixed an issue when a project with {@code .arm} or {@code .neon} suffixes in + {@code LOCAL_SRC_FILES} also used {@code APP_STL}. With {@code APP_STL}, the + {@code ndk-build} script searches for C++ files in {@code LOCAL_SRC_FILES} before + adding STL {@code header/lib} paths to compilation. Modified {@code ndk-build} to + filter out {@code .arm} and {@code .neon} suffixes before the search, otherwise items + in {@code LOCAL_SRC_FILES} like {@code myfile.cpp.arm.neon} won't be compiled as C++ + code. +
- Fixed {@code binutils-2.21/ld.bfd} to be capable of linking object from older + binutils without {@code tag_FP_arch}, which was producing assertion fail + error messages in GNU Binutils. + (Issue 35209) + +
- Removed Unknown EABI object attribute 44 warning when + {@code binutils-2.19/ld} links prebuilt object by newer {@code binutils-2.21} +
- Fixed an issue in GNU {@code stdc++} compilation with both {@code -mthumb} and + {@code -march=armv7-a}, by modifying {@code make-standalone-toolchain.sh} to populate + {@code headers/libs} in sub-directory {@code armv7-a/thumb}. + (Issue 35616) + +
- Fixed unresolvable R_ARM_THM_CALL relocation error. + (Issue 35342) + +
- Fixed internal compiler error at {@code reload1.c:3633}, caused by the ARM + back-end expecting the wrong operand type when sign-extend from {@code char}. + (GCC Issue 50099) +
- Fixed internal compiler error with negative shift amount. + (GCC Issue) +
+
+ - Fixed {@code -fstack-protector} for X86, which is also the default for the + {@code ndk-build} x86 ABI target. + +
- MIPS-specific fixes:
+
-
+
- Fixed {@code STLport} endian-ness by setting {@code _STLP_LITTLE_ENDIAN} to 1 when + compiling MIPS {@code libstlport_*}. +
- Fixed GCC {@code __builtin_unreachable} issue when compiling LLVM. + (GCC Issue 54369) +
- Backported fix for {@code cc1} compile process consuming 100% CPU. + (GCC Issue 50380) +
+
+ - GNU Debugger-specific fixes:
+
-
+
- Disabled Python support in gdb-7.x at build, otherwise the gdb-7.x configure + function may pick up whatever Python version is available on the host and build + {@code gdb} with a hard-wired dependency on a specific version of Python. + (Issue 36120) + +
- Fixed {@code ndk-gdb} when {@code APP_ABI} contains {@code all} and matchs none + of the known architectures. + (Issue 35392) + +
- Fixed Windows pathname support, by keeping the {@code :} character if it looks + like it could be part of a Windows path starting with a drive letter. + (GDB Issue 12843) + +
- Fixed adding of hardware breakpoint support for ARM in {@code gdbserver}. + (GDB Issue) + +
- Added fix to only read the current {@code solibs} when the linker is consistent. + This change speeds up {@code solib} event handling. + (Issue 37677) + +
- Added fix to make repeated attempts to find {@code solib} breakpoints. GDB now + retries {@code enable_break()} during every call to {@code svr4_current_sos()} until + it succeeds. + (Change 43563) +
- Fixed an issue where {@code gdb} would not stop on breakpoints placed in + {@code dlopen-ed} libraries. + (Issue 34856) + +
- Fixed {@code SIGILL} in dynamic linker when calling {@code dlopen()}, on system + where {@code /system/bin/linker} is stripped of symbols and + {@code rtld_db_dlactivity()} is implemented as {@code Thumb}, due to not preserving + {@code LSB} of {@code sym_addr}. + (Issue 37147) + +
+
+ - Fixed an issue where running {@code make-standalone-toolchain.sh} with root privileges
+ resulted in the stand alone tool chain being inaccessible to some users.
+ (Issue 35279)
+
- Other bug fixes: + +
-
+
-
+
- Fixed NDK headers:
+
-
+
- Fixed {@code arch-mips/include/asm/*} code that was incorrectly removed from + original kernel. (Change + 43335) +
- Replaced struct member data {@code __unused} with {@code __linux_unused} in + {@code linux/sysctl.h} and {@code linux/icmp.h} to avoid conflict with + {@code #define __unused} in {@code sys/cdefs.h}. +
- Fixed {@code fenv.h} for enclosed C functions with {@code __BEGIN_DECLS} and + {@code __END_DECLS}. +
- Removed unimplemented functions in {@code malloc.h}. +
- Fixed {@code stdint.h} defintion of {@code uint64_t} for ANSI compilers. + (Issue 1952) +
- Fixed preprocessor macros in {@code <arch>/include/machine/*}. +
- Replaced {@code link.h} for MIPS with new version supporting all platforms. +
- Removed {@code linux-unistd.h} +
- Move GLibc-specific macros {@code LONG_LONG_MIN}, {@code LONG_LONG_MAX} and + {@code ULONG_LONG_MAX} from {@code <pthread.h>} to {@code <limits.h>}. +
+ - Fixed a buffer overflow in {@code ndk-stack-parser}. +
- Fixed {@code _STLP_USE_EXCEPTIONS}, when not defined, to omit all declarations + and uses of {@code __Named_exception}. Compiling and use of {@code __Named_exception} + settings only occurs when {@code STLport} is allowed to use exceptions. +
- Fixed building of Linux-only NDK packages without also building Windows code. Use the
+ following settings to perform this type of build:
+
./build/tools/make-release.sh --force --systems=linux-x86
+ - Fixed {@code libc.so} so it does not export {@code atexit()} and {@code __do_handler}.
+ These symbols are exported for ARM builds by the system version of the C library to
+ support legacy native libraries. NDK-generated should never reference them directly.
+ Instead, each shared library or executable should embed its own version of these symbols,
+ provided by {@code crtbegin_*.o}.
+
If your project is linked with the {@code -nostdlib -Wl,--no-undefined} options, you + must provide your own {@code __dso_handle} because {@code crtbegin_so.o} is not linked in + this case. The content of {@code __dso_handle} does not matter, as shown in the following + example code:
++extern "C" { + extern void *__dso_handle __attribute__((__visibility__ ("hidden"))); + void *__dso_handle; +} ++
+ - Fixed symbol decoder for ARM used in {@code objdump} for {@code plt} entries to + generate a more readable form {@code function@plt}. +
- Removed the following symbols, introduced in GCC 4.6 {@code libgcc.a}, from + the X86 platform {@code libc.so} library: {@code __aeabi_idiv0}, {@code __aeabi_ldiv0}, + {@code __aeabi_unwind_cpp_pr1}, and {@code __aeabi_unwind_cpp_pr2}. +
- Removed unused {@code .ctors}, {@code .dtors}, and {@code .eh_frame} in MIPS + {@code crt*_so.S}. +
- Updated {@code ndk-gdb} so that it only takes the last line of output for + {@code ndk-build} {@code DUMP_XXXX}. This change ensures that if {@code Application.mk} or + {@code Android.mk} print something with {@code $(info ...)} syntax, it does not get + injected into the result of {@code DUMP_XXXX}. + (More info) +
+ - Fixed NDK headers:
+
- Other changes: + +
-
+
-
+
- Removed {@code arch-x86} and {@code arch-mips} headers from + {@code platforms/android-[3,4,5,8]}. Those headers were incomplete, since both X86 and + MIPS ABIs are only supported at API 9 or higher. +
- Simplified c++ include path in standalone packages, as shown below.
+ (Issue 35279)
+
+<path>/arm-linux-androideabi/include/c++/4.6.x-google + to: +<path>/include/c++/4.6/ +
+ - Fixed {@code ndk-build} to recognize more C++ file extensions by default: + {@code .cc .cp .cxx .cpp .CPP .c++ .C}. You may still use {@code LOCAL_CPP_EXTENSION} to + overwrite these extension settings. +
- Fixed an issue in {@code samples/san-angeles} that caused a black screen or freeze + frame on re-launch. +
- Replaced deprecated APIs in NDK samples.
+ (Issue 20017)
+
-
+
- {@code hello-gl2} from android-5 to android-7 +
- {@code native-activity} from android-9 to android-10 +
- {@code native-audio} from android-9 to android-10 +
- {@code native-plasma} from android-9 to android-10 +
+ - Added new branding for Android executables with a simpler scheme in section
+ {@code .note.android.ident} (defined in {@code crtbegin_static/dynamic.o}) so that
+ debugging tools can act accordingly. The structure member and values are defined as
+ follows:
+
+static const struct { + int32_t namesz; /* = 8, sizeof ("Android") */ + int32_t descsz; /* = 1 * sizeof(int32_t) */ + int32_t type; /* = 1, ABI_NOTETYPE */ + char name[sizeof "Android"]; /* = "Android" */ + int32_t android_api; /* = 3, 4, 5, 8, 9, 14 */ +} ++The previous branding options in section {@code .note.ABI-tag} are deprecated.
+
+ - Added a new script {@code run-tests-all.sh} which calls {@code run-tests.sh} and + {@code standalone/run.sh} with various conditions. The script {@code run-tests.sh} runs + without the {@code --abi} option, and is enhanced to compile most of the tests for all + supported ABIs and run on all attached devices +
