Hi Adhemerval, Some UBSan tests are timing out randomly. http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full ex: http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full/builds/902 http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full/builds/894 http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full/builds/906

Found some stray descriptor table accessors that had non-optimal assembler constraints. Use "q" to get word, high and low byte access without forcing a specific register constraint. Add desc as a memory output operand. Also, get_base was completely unused. Deprecate it. The function get_limit is also unused, but I did not deprecate it; it could be used in arch/i386/mm/fault.c.

Hello, I was implementing the llvm_any_type in my intrinsic def int_csa_xxx : Intrinsic<[llvm_any_ty], [llvm_i32_ty]>; as the following in its corresponding builtins in Builtins.def: BUILTIN(__builtin_xxx, "v.", "nt") the "t" was sufficient here to not perform any type checking. The type checking was handled in CGBuiltin.cpp. This was working until

I am building LLVM on OS X 10.7.5 with cmake. Under this configuration some ASan and UBSan tests are failing: $ make check-ubsan … ******************** Testing Time: 2.36s ******************** Failing Tests (11): UndefinedBehaviorSanitizer :: Float/cast-overflow.cpp UndefinedBehaviorSanitizer :: Integer/add-overflow.cpp UndefinedBehaviorSanitizer :: Integer/div-zero.cpp

Hi Evgeniy, So, to XFAIL some UBSAN failues, I found an issue: UndefinedBehaviorSanitizer-AddressSanitizer :: TestCases/TypeCheck/vptr.cpp UndefinedBehaviorSanitizer-Standalone :: TestCases/Misc/missing_return.cpp These two tests fail on that configuration, but pass when reversed. So, if I XFAIL: armv7l..., I get the following error: UndefinedBehaviorSanitizer-AddressSanitizer ::

Fairly straightforward code motion in system.h into the sub-arch layer. Affected functionality include control register accessors, which are virtualizable but with great overhead due to the #GP cost; wbinvd, and most importantly, halt and interrupt control, which is non-virtualizable. Since read_cr4_safe can never fault on a VMI kernel (P5+ processor is required for VMI), we can omit the fault

Currently all config space fields are of the type __uXX. This confuses people and some drivers (notably vdpa) access them using CPU endian-ness - which only works well for legacy or LE platforms. Update virtio_cread/virtio_cwrite macros to allow __virtioXX and __leXX field types. Follow-up patches will convert config space to use these types. Signed-off-by: Michael S. Tsirkin <mst at
