vex x86->IR: unhandled instruction bytes: 0x66 0xF 0x3A 0x63 ==5187== valgrind: Unrecognised instruction at address 0x6d8bf37. ==5187== at 0x6D8BF37: __intel_sse4_strlen (in /system/lib/libintlc.so) ==5187== by 0x55649E1: android::camera2::Aiq3A::_init3A() (Aiq3A.cpp:205) ==5187== by 0x55128F3: android::camera2::Camera3HAL::init() (Camera3HAL.cpp:184) ==5187== by 0x558F2FA: openCameraHardware(int, hw_module_t const*, hw_device_t**) (Camera3HALModule.h:80) ==5187== by 0x558FC9D: hal_dev_open(hw_module_t const*, char const*, hw_device_t**) (Camera3HALModule.h:157) ==5187== by 0x4A35E67: android::Camera3Device::initialize(camera_module*) (in /system/lib/libcameraservice.so) ==5187== by 0x127800: android::camera2::tests::CameraModuleTest_LoadModule_Test::TestBody() (CameraModuleTests.cpp:51) ==5187== by 0x156399: void testing::internal::HandleExceptionsInMethodIfSupported<testing::Test, void>(testing::Test*, void (testing::Test::*)(), char const*) [clone .isra.366] [clone .constprop.499] (gtest.cc:2078) ==5187== Your program just tried to execute an instruction that Valgrind ==5187== did not recognise. There are two possible reasons for this. ==5187== 1. Your program has a bug and erroneously jumped to a non-code ==5187== location. If you are running Memcheck and you just saw a ==5187== warning about a bad jump, it's probably your program's fault. ==5187== 2. The instruction is legitimate but Valgrind doesn't handle it, ==5187== i.e. it's Valgrind's fault. If you think this is the case or ==5187== you are not sure, please let us know and we'll try to fix it. ==5187== Either way, Valgrind will now raise a SIGILL signal which will ==5187== probably kill your program. Reproducible: Always
Seems to be this C instruction from sse4_2: _mm_cmpistri
pcmpistri is an SSE4.2 instruction. SSE4 isn't supported in 32 bit mode, only 64 bit mode. 32 bit mode supports only up to and including SSSE3. http://www.valgrind.org/docs/manual/manual-core.html#manual-core.limits There are no current plans to support SSE4 on 32-bit. Please use 64-bit.
