| * Avoid accidentally using the host's native 'as' command.Alistair Strachan2016-05-131-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When invoking clang for the host to assemble .S files, the -B flag would not be provided, which allowed the host prebuilt clang to use an 'as' from the native environment. Most of the time this "just works", but some newer 'as' versions cause problems with the older prebuilt toolchain, for example by generating unsupported relocation types. To avoid this problem, simply use the -B flag to tell clang to invoke the assembler from the correct prebuilt gcc prefix.

* Add -mfpu=neon-vfpv4 if cpu is kraitPirama Arumuga Nainar2015-10-311-1/+1
| | | | | | | | | | | | | | | | | Upstream clang r239152 (http://reviews.llvm.org/D10239) caused a pretty significant change in behavior. Passing an FPU feature via -mfpu disables any feature not supported by those flags (in addition to the old behavior of enabling features supported by the flags). For e.g., -mfpu=neon used to just pass +neon, +vfp3 as target features to the backend. Now, -mfpu=neon also passes -vfp4, -fp16, -fp-armv8. The backend has always disabled implied feature bits if a feature is disabled. Upon seeing the target feature -vfp4, it will disable any processor/feature that implies vfp4, including the bit that the processor is a Krait. Since Krait has both Neon and vfp4, it is safe to pass '-mfpu=neon-vfpv4'. Change-Id: Ibbb992e80b8cbc8dc36d5df556885d0912baea22

* Fix AddressSanitizer link order and multilib setup.Evgenii Stepanov2015-05-123-3/+9
| | | | | | | | | | | | | | | ASan runtime library (when using dynamic linking) must be the first dependency of the main executable to achieve correct symbol interposition. This matches how the clang driver works. In multilib setup, ASan-RT name depends on the target arch: /system/lib/libclang_rt.asan-arm-android.so /system/lib64/libclang_rt.asan-arm64-android.so We also set RPATH to /system/lib/asan or /system/lib64/asan to have a place for ASan-only versions of system libraries.

| | | | | | | | | | | | | | | | | | | | Some of the ubsan checks expose a few pathological performance cases in clang, and thus aren't suited to be used in SANITIZE_HOST.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than adding LOCAL_UB_SANITIZER, LOCAL_THREAD_SANITIZER, etc for each new sanitizer, deprecate LOCAL_ADDRESS_SANITIZER in favor of LOCAL_SANITZE that mirrors the behavior of -fsanitize=<sanitizers>. For example, the following will use both asan and ubsan: LOCAL_SANITIZE := address undefined We'll leave LOCAL_ADDRESS_SANITIZER around for compatibility until we can clean up the tree.

| | | | | | | | | | | | http://llvm.org/bugs/show_bug.cgi?id=15086, llvm tail call optimization is wrong for x86. For Android/x86 to use SSE* instructions safely, stack should be 16-byte aligned before JNI function call, which isn't true for all x86 device, so -mstackrealign should be the default.

* Let clang decide ASan linker flags for the host.Dan Albert2014-12-051-9/+2
| | | | | | | | | | | | Pass -fsanitize=address instead of manually specifying asan libraries and other linker flags. Note that we enable LOCAL_ALLOW_UNDEFINED_SYMBOLS by default for host builds because ASAN only links symbols in the final executable, so there will _always_ be undefined symbols in intermediate libraries.
