<dl>
<dt>Important changes:</dt>
<dd>
<ul>
<li>Integrated the workaround for Cortex-A53 Erratum 843419 into the
{@code aarch64-linux-android-4.9} linker. For more information on this workaround, see
<a href="https://sourceware.org/ml/binutils/2015-03/msg00446.html">Workaround for cortex-a53
erratum 843419.</a></li>
<li>Added Clang 3.6; {@code NDK_TOOLCHAIN_VERSION=clang} now picks that version
of Clang by default.</li>
<li>Removed Clang 3.4.</li>
<li>Removed GCC 4.6.</li>
<li>Implemented multithreading support in {@code ld.gold} for all architectures. It can
now link with or without support for multithreading; the default is to do it without.
<ul>
<li>To compile with multithreading, use the {@code --threads} option.</li>
<li>To compile without multithreading, use the {@code --no-threads} option.</li>
</ul>
</li>
<li>Upgraded GDB/gdbserver to 7.7 for all architectures.</li>
<li>Removed the NDK package for 32-bit Darwin.</li>
</ul>
</dd>
<dl>
<dt>Important bug fixes:</dt>
<dd>
<ul>
<li>Fixed a crash that occurred when there were OpenMP loops outside of the main thread.</li>
<li>Fixed a GCC 4.9 internal compiler error (<i>ICE</i>) that occured when the user declared
{@code #pragma GCC optimize ("O0")}, but had a different level of optimization specified
on the command line. The {@code pragma} takes precedence.</li>
<li>Fixed an error that used to produce a crash with the following error message:
<pre>
in add_stores, at var-tracking.c:6000
</pre>
</li>
<li>Implemented a workaround for a Clang 3.5 issue in which LLVM auto-vectorization
generates {@code llvm.cttz.v2i64()}, an instruction with no counterpart in the ARM
instruction set.</li>
</ul>
</dd>
<dt>Other bug fixes:</dt>
<dd>
<ul>
<li>Made the following header and library fixes:</li>
<ul>
<li>Fixed {@code PROPERTY_*} in {@code media/NdkMediaDrm.h}.</li>
<li>Fixed {@code sys/ucontext.h} for {@code mips64}.</li>
<li>Dropped the Clang version check for {@code __builtin_isnan} and
{@code __builtin_isinf}.</li>
<li>Added {@code android-21/arch-mips/usr/include/asm/reg.h}
and {@code android-21/arch-mips64/usr/include/asm/reg.h}.</li>
</ul>
</li>
<li>Fixed a spurious array-bounds warning that GCC 4.9 produced for x86, and reenabled the
array bounds warning that GCC 4.9 had produced for ARM. The warning for ARM had
previously been unconditionally disabled.</li>
<li>Fixed Clang 3.5 for {@code mips} and {@code mips64} to create a writable
{@code .gcc_except_table} section, thus matching GCC behavior. This change allows you
to avoid the following linker warning:
<pre>
.../ld: warning: creating a DT_TEXTREL in a shared object
</pre>
</li>
<li>Backported a fix for {@code compiler-rt} issues that were causing crashes when Clang
compiled for {@code mips64}. For more information, see LLVM Issue
<a href="http://llvm.org/bugs/show_bug.cgi?id=20098">20098</a>.</li>
<li>Fixed Clang 3.5 crashes that occurred on non-ASCII comments. (Issue
<a href="https://code.google.com/p/android/issues/detail?id=81440">81440</a>)</li>
<li>Fixed {@code stlport collate::compare} to return {@code -1} and {@code 1}. Previously,
it had returned arbitrary signed numbers.</li>
<li>Fixed {@code ndk-gdb} for 64-bit ABIs. (Issue
<a href="https://code.google.com/p/android/issues/detail?id=118300">118300</a>)</li>
<li>Fixed the crash that the HelloComputeNDK sample for RenderScript was producing on
Android 4.4 (Android API level 19). For more information, see
<a href="http://stackoverflow.com/questions/28057049/targeting-pre-lollipop-devices-using-renderscript-from-ndk-c">this page</a>.</li>
<li>Fixed {@code libc++ __wrap_iter} for GCC. For more information, see LLVM Issue
<a href="http://llvm.org/bugs/show_bug.cgi?id=22355">22355</a>.</li>
<li>Fixed {@code .asm} support for ABI {@code x86_64}.</li>
<li>Implemented a workaround for the GCC 4.8 {@code stlport} issue. (Issue
<a href="https://android-review.googlesource.com/#/c/127773">127773</a>)</li>
<li>Removed the trailing directory separator {@code \\} from the project path in Windows.
(Issue <a href="https://code.google.com/p/android/issues/detail?id=160584">160584</a>)
</li>
<li>Fixed a {@code no rule to make target} error that occurred when compiling a single
{@code .c} file by executing the {@code ndk-build.cmd} command from {@code gradle}. (Issue
<a href="https://code.google.com/p/android/issues/detail?id=66937">66937</a>)</li>
<li>Added the {@code libatomic.a} and {@code libgomp.a} libraries that had been missing from
the following host toolchains:
<ul>
<li>{@code aarch64-linux-android-4.9}</li>
<li>{@code mips64el-linux-android-4.9}</li>
<li>{@code mipsel-linux-android-4.9}</li>
<li>{@code x86_64-4.9}</li>
</ul>
</ul>
</dd>
<dt>Other changes:</dt>
<dd>
<ul>
<li>Added {@code ld.gold} for {@code aarch64}. The default linker remains {@code ld.bfd}.
To explicitly enable {@code ld.gold}, add {@code -fuse-ld=gold} to the
{@code LOCAL_LDFLAGS} or {@code APP_LDFLAGS} variable.</li>
<li>Built the MIPS and MIPS64 toolchains with {@code binutils-2.25}, which provides improved
R6 support.</li>
<li>Made {@code -fstandalone-debug} (full debug info) a default option for Clang.</li>
<li>Replaced {@code -fstack-protector} with {@code -fstack-protector-strong} for
the ARM, AArch64, X86, and X86_64 toolchains for GCC 4.9, Clang 3.5, and
Clang 3.6.</li>
<li>Added the {@code --package} command-line switch to {@code ndk-gdb} to allow the build
system to override the package name. (Issue
<a href="https://code.google.com/p/android/issues/detail?id=56189">56189</a>)</li>
<li> Deprecated {@code -mno-ldc1-stc1} for MIPS. This option may not work with the new
{@code -fpxx} and {@code -mno-odd-spreg} options, or with the FPXX ABI.</li>
<li>Added MIPS MSA and R6 detection to {@code cpu-features}.</li>
