This version is a nearly pure upstream Clang. Additions Clang now provides support for emulated TLS. This limitation does not apply when running on Android 6. The NDK will neither be upgrading to 5. Maintenance for miscompiles and internal compiler errors in 4.
Removals Removed GCC 4. All targets now use GCC 4. Previously, it had been synchronized with r They are instead available on GitHub. The documentation is no longer included in the NDK package. Instead, it is on the Android developer website. Additions Added a native tracing API to android Added a native multinetwork API to android Enabled libc, m, and dl to provide versioned symbols, starting from API level Removed sed. Removed mclinker.
Removed Perl. Removed from all versions of NDK libc, m, and dl all symbols which the platform versions of those libs do not support. Partially removed support for mips64r2. The rest will be removed in the future. Other changes Changed ARM standalone toolchains to default to arm7. You can restore the old behavior by passing specifying the -target option as armv5te-linux-androideabi.
Changed the build system to use -isystem for platform includes. Warnings that bionic causes no longer break app builds. Expect support for Froyo and older to be dropped in a future release. Added the following capabilities to cpufeatures: Detect SSE4. Updated byteswap. Fixed fegetenv and fesetenv for arm. Binutils Additions Added a new option: --pic-veneer. Removals The bit Windows package no longer contains ld.
You can instead get ld. For more information on this change, see the comments here. Improved reliability of Gold for aarch The default will likely switch in the next release.
GDB Removals Removed ndk-gdb in favor of ndk-gdb. Changes Updated gdb to version 7. Improved performance. Improved error messages. Fixed relative project paths. Stopped Ctrl-C from killing the backgrounded gdbserver. Improved Windows support. Known issues x86 ASAN does not currently work.
For more information, see the discussion here. For more information, see the comments here. This behavior is not a regression from r10e. Important changes: Integrated the workaround for Cortex-A53 Erratum into the aarchlinux-android For more information on this workaround, see Workaround for cortex-a53 erratum Added Clang 3.
Removed Clang 3. Removed GCC 4. Implemented multithreading support in ld. It can now link with or without support for multithreading; the default is to do it without. To compile with multithreading, use the --threads option. To compile without multithreading, use the --no-threads option.
Removed the NDK package for bit Darwin. Important bug fixes: Fixed a crash that occurred when there were OpenMP loops outside of the main thread. Fixed a GCC 4. The pragma takes precedence. Fixed a spurious array-bounds warning that GCC 4. The warning for ARM had previously been unconditionally disabled. Fixed Clang 3. This change allows you to avoid the following linker warning Issue Fixed stlport collate::compare to return -1 and 1. Previously, it had returned arbitrary signed numbers. Fixed ndk-gdb for bit ABIs.
For more information, see this page. Implemented a workaround for the GCC 4. Issue Fixed a no rule to make target error that occurred when compiling a single. Issue Added the libatomic. The default linker remains ld. To explicitly enable ld. Made -fstandalone-debug full debug info a default option for Clang. Added the --package command-line switch to ndk-gdb to allow the build system to override the package name.
Deprecated GCC 4. GCC 4. The NDK toolchain assumes a byte stack alignment. The tools and options used by default enforce this rule.
A user writing assembly code must make sure to preserve stack alignment, and ensure that other compilers also comply with this rule. For more information on this change, see the Address Sanitizer project.
This change has a number of implications, which are discussed in Developer Preview Issue These implications do not apply to shared libraries. Important bug fixes: Made more fixes related to A53 Errata in the aarchlinux-android As part of this, GCC passes a new option, --fix-cortex-a , when -mfix-cortex-a enabled by default is specified.
For more information, see this binutils message and this binutils message. The fix itself had been implemented in r10c. Also, added a prototype in stdlib. Issue Fixed stdatomic. Changed sysconf return value type from int to long. Issue Removed bash-specific code from ndk-gdb. Issue Removed bash-specific code from make-standalone-toolchain.
Issue Revised documentation concerning a fix for System. Issue Fixed a problem that was preventing bit packages from extracting on Ubuntu Issue Clarified "requires executable stack" warning from ld. Issue Android NDK r10c October Important changes: Made the following changes to download structure: Each package now contains both the and the bit headers, libraries, and tools for its respective platform. STL libraries with debugging info no longer need be downloaded separately.
Changed everything previously called Android-L to the official release designation: android Updated GCC 4. Major differences from the upstream version of GCC 4. Note that: ARM and x86 default to using the integrated assembler. If this causes issues, use -fno-integrated-as as a workaround.
Clang 3. Made it possible to enter ART debugging mode, when debugging on an Android 5. Removed support for Clang 3. Updated mclinker to 2. Specify ICF using the --icf option. Important bug fixes: Fixed an internal compiler error with GCC4.
Issue Fixed an internal compiler error with GCC4. Issue Fixed incorrect code that GCC4. Issue Fixed GCC4. Disable the workaround by specifying -mno-fix-cortex-a Fixed stdatomic. The signal. You may remove any existing definition of struct ucontext. This change restores r9d behavior; previous versions of r10 contained placeholder files.
This support had been absent from r10 and r10b because those versions of GCC had been compiled with binutils It now does. This setting brings improved LTO support. Issue Fixed an issue related to -flto with GCC 4. The error message read To compile native-codec, you must use a bit NDK package, which is where all the Android-L headers are located. Important bug fixes: Fixed gdb 7. Issues and Fixed GCC 4. Other bug fixes: Removed stdio. Fixed atexit.
Made the following fixes to the Android-L headers: Added the following functions to ctype. Changed the ptrace prototype to long ptrace int, Removed sha1.
Other changes: Updated mipsel-linux-android Change list Note that: GCC 4. Clang is currently version 3. Android-L is the first level with bit support. Note that this API level is a temporary one, and only for L-preview. An actual API level number will replace it at L-release.
The cpu-features library has been updated for the ARMv8 kernel. Recompile your code with the new version. New media APIs and a native-codec sample. An updated Android. GLES 3. Added GCC 4. For ndk-build, enable bit, GCC 4. Upgraded GDB to version 7. Note that: All tests except for locale now pass for Clang 3. As of GCC 4. Rebuilding it requires the use of a different compiler. Note that Clang 3.
Fixed a Clang 3. Fixed the Clang 3. Fixed the following Clang 3. ARM: unsigned. Removed non-existent symbols from bit libc. For more information, see the commit message accompanying AOSP change list Fixed GCC warning about redefinition of putchar. Fixed make-standalone-toolchain. Runs in directories other than the NDK install directory. This change decreases the likelihood of exceeding the 32K length limit.
Fixed native-audio's inability to build in debug mode. Fixed gdb's inability to print extreme floating-point numbers. The problem was that Clang added -pie for Android targets if neither -shared nor -static existed. This behavior, which was incorrect, caused the linker to complain that -shared and -pie could not co-exist. There is currently no support for bit types. For more information, see the section on ARM Neon intrinsics support in the x86 documentation.
This optimization sometimes reduces instruction count when accessing global variables. As an example, see the build. They now have both it and Thumb mode. It is now possible to call the make-standalone-toolchain. For make to behave as expected, you cannot specify both armeabi-v7a and armeabi-v7a-hard as make targets i. Doing so causes one of them to be ignored.
Updated MClinker to 2. Issue Important bug fixes: Fixed an uncaught throw from an unexpected exception handler for GCC 4. This wrong setting was a regression introduced in release r9c. Added scalbln , scalblnf , and scalblnl to x86 libm.
Fixed samples Teapot and MoreTeapots: Solved a problem with Tegra 2 and 3 chips by changing specular variables to use medium precision. Values for specular power can now be less than 1. Screen rotation does not trigger onSystemUiVisibilityChange , and so does not restore immersive mode. Fixed ndk-gdb-py. Issue Fixed the make-standalone-toolchain. Improved the speed of the make-standalone-toolchain. Important bug fixes: Fixed a problem with GCC 4.
This problem prevented the frame pointer from reliably accessing a variable in the stack frame. Issue Fixed GCC 4. For ongoing information on fixes for -mhard-float with STL, please follow Issue Added utimensat to libc. These libraries are now included for all Android API levels 12 through Introduced futimens into libc. Updated them to use immersive mode on Android API level 19 and higher. Fixed ndk-build fails that happen in cygwin when the NDK package is referenced via symlink.
Fixed ndk-build. Issue Fixed the ndk-stack script to proceed even when it can't parse a frame due to inability to find a routine, filename, or line number. In any of these cases, it prints?? This option helps the ndk-stack script provide better a stack dump across STL. Used the ar tool in Deterministic mode option -D to build static libraries.
For information on added APIs, see commit messages for Changes and Added support for -mhard-float in the existing armeabi-v7a ABI. These samples run on devices with Android 4. Issue Fixed Clang 3. Fixed issue with MIPS 4. Issue , Issue Removed non-existent functions imaxabs and imaxdiv from header inttypes.
Issue Added missing mkdtemp function, which already exists in bionic header stdlib. Fixed MCLinker to allow multiple occurrences of the following options: -gc-sections and --eh-frame-hdr.
Fixed MCLinker to accept the --no-warn-mismatch option. Fixed several issues with Clang -integrated-as option so it can pass tests for ssax-instructions and fenv. For more information, see the GCC patch. Issue Fixed extra quotes in ndk-build output on Windows.
Modified GCC builds so that all libgcc. Fixed bitmap-plasma to draw to full screen rather than a x pixel area. Since GCC 4. Added MCLinker to support Windows hosts.
Since ld. Added ndk-depends tool which prints ELF library dependencies. Issue Fixed libc. Issue Updated the x86 libc. Change Fixed GCC 4.
