Android NDK, Revision 10e (May 2015)

+-
+
- Important changes: +
-
+
-
+
- Integrated the workaround for Cortex-A53 Erratum 843419 into the + {@code aarch64-linux-android-4.9} linker. For more information on this workaround, see + Workaround for cortex-a53 + erratum 843419. + +
- Added Clang 3.6; {@code NDK_TOOLCHAIN_VERSION=clang} now picks that version + of Clang by default. + +
- Removed Clang 3.4. + +
- Removed GCC 4.6. + +
- 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.
+
-
+
- To compile with multithreading, use the {@code --threads} option. +
- To compile without multithreading, use the {@code --no-threads} option. +
+
+ - Upgraded GDB/gdbserver to 7.7 for all architectures. + +
- Removed the NDK package for 32-bit Darwin. +
+ - Important bug fixes: +
-
+
-
+
- Fixed a crash that occurred when there were OpenMP loops outside of the main thread. + +
- Fixed a GCC 4.9 internal compiler error (ICE) 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. + +
- Fixed an error that used to produce a crash with the following error message:
+
+in add_stores, at var-tracking.c:6000 +
+
+
+ - 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. +
+
+ - Other bug fixes: +
-
+
-
+
- Made the following header and library fixes: +
- Fixed {@code PROPERTY_*} in {@code media/NdkMediaDrm.h}. +
- Fixed {@code sys/ucontext.h} for {@code mips64}. +
- Dropped the Clang version check for {@code __builtin_isnan} and + {@code __builtin_isinf}. +
- Added {@code android-21/arch-mips/usr/include/asm/reg.h} + and {@code android-21/arch-mips64/usr/include/asm/reg.h}. +
- 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. + +
- 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:
+
+
+.../ld: warning: creating a DT_TEXTREL in a shared object +
+
+
+ - Backported a fix for {@code compiler-rt} issues that were causing crashes when Clang + compiled for {@code mips64}. For more information, see LLVM Issue + 20098. + +
- Fixed Clang 3.5 crashes that occurred on non-ASCII comments. (Issue + 81440) + +
- Fixed {@code stlport collate::compare} to return {@code -1} and {@code 1}. Previously, + it had returned arbitrary signed numbers. + +
- Fixed {@code ndk-gdb} for 64-bit ABIs. (Issue + 118300) + +
- Fixed the crash that the HelloComputeNDK sample for RenderScript was producing on + Android 4.4 (Android API level 19). For more information, see + this page. + +
- Fixed {@code libc++ __wrap_iter} for GCC. For more information, see LLVM Issue + 22355. + +
- Fixed {@code .asm} support for ABI {@code x86_64}. + +
- Implemented a workaround for the GCC 4.8 {@code stlport} issue. (Issue + 127773) + +
- Removed the trailing directory separator {@code \\} from the project path in Windows. + (Issue 160584) + + +
- 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 + 66937) + +
- Added the {@code libatomic.a} and {@code libgomp.a} libraries that had been missing from
+ the following host toolchains:
+
-
+
- {@code aarch64-linux-android-4.9} +
- {@code mips64el-linux-android-4.9} +
- {@code mipsel-linux-android-4.9} +
- {@code x86_64-4.9} +
-
+
+
+ - Other changes: +
-
+
-
+
- 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. + +
- Built the MIPS and MIPS64 toolchains with {@code binutils-2.25}, which provides improved + R6 support. + +
- Made {@code -fstandalone-debug} (full debug info) a default option for Clang. + +
- 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. + +
- Added the {@code --package} command-line switch to {@code ndk-gdb} to allow the build + system to override the package name. (Issue + 56189) + +
- 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. + +
- Added MIPS MSA and R6 detection to {@code cpu-features}. + +
