# 19074450	16-Sep-2015	Adhemerval Zanella <adhemerval.zanella@linaro.org>	[MSan] Enable MSAN for aarch64 This patch enabled msan for aarch64 with 39-bit VMA and 42-bit VMA. As defined by lib/msan/msan.h the memory layout used is for 39-bit is: 00 0000 0000 - 40 0000 0 [MSan] Enable MSAN for aarch64 This patch enabled msan for aarch64 with 39-bit VMA and 42-bit VMA. As defined by lib/msan/msan.h the memory layout used is for 39-bit is: 00 0000 0000 - 40 0000 0000: invalid 40 0000 0000 - 43 0000 0000: shadow 43 0000 0000 - 46 0000 0000: origin 46 0000 0000 - 55 0000 0000: invalid 55 0000 0000 - 56 0000 0000: app (low) 56 0000 0000 - 70 0000 0000: invalid 70 0000 0000 - 80 0000 0000: app (high) And for 42-bit VMA: 000 0000 0000 - 100 0000 0000: invalid 100 0000 0000 - 11b 0000 0000: shadow 11b 0000 0000 - 120 0000 0000: invalid 120 0000 0000 - 13b 0000 0000: origin 13b 0000 0000 - 2aa 0000 0000: invalid 2aa 0000 0000 - 2ab 0000 0000: app (low) 2ab 0000 0000 - 3f0 0000 0000: invalid 3f0 0000 0000 - 400 0000 0000: app (high) Most of tests are passing with exception of: * Linux/mallinfo.cc * chained_origin_limits.cc * dlerror.cc * param_tls_limit.cc * signal_stress_test.cc * nonnull-arg.cpp The 'Linux/mallinfo.cc' is due the fact AArch64 returns the sret in 'x8' instead of default first argument 'x1'. So a function prototype that aims to mimic (by using first argument as the return of function) won't work. For GCC one can make a register alias (register var asm ("r8")), but for clang it detects is an unused variable and generate wrong code. The 'chained_origin_limits' is probably due a wrong code generation, since it fails only when origin memory is used (-fsanitize-memory-track-origins=2) and only in the returned code (return buf[50]). The 'signal_streess_test' and 'nonnull-arg' are due currently missing variadic argument handling in memory sanitizer code instrumentation on LLVM side. Both 'dlerror' and 'param_tls_test' are unknown failures that require further investigation. All the failures are XFAIL for aarch64 for now. llvm-svn: 247809 show more ...

# 8e1162c7	08-Sep-2014	Alexey Samsonov <vonosmas@gmail.com>	Implement nonnull-attribute sanitizer Summary: This patch implements a new UBSan check, which verifies that function arguments declared to be nonnull with __attribute__((nonnull)) are actually nonnu Implement nonnull-attribute sanitizer Summary: This patch implements a new UBSan check, which verifies that function arguments declared to be nonnull with __attribute__((nonnull)) are actually nonnull in runtime. To implement this check, we pass FunctionDecl to CodeGenFunction::EmitCallArgs (where applicable) and if function declaration has nonnull attribute specified for a certain formal parameter, we compare the corresponding RValue to null as soon as it's calculated.
