[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

Fix a veritable conucopia of bugs in the readdir_r interceptors. First, the reason I came here: I forgot to look at readdir64_r which had the exact same bug as readdir_r. However, upon applying the same quick-fix and testing it I discovered that it still didn't work at all. As a consequence, I spent some time studying the code and thinking about it and fixed several other problems. Second, the code was checking for a null entry and result pointer, but there is no indication that null pointers are viable here. Certainly, the spec makes it extremely clear that there is no non-error case where the implementation of readdir_r fails to dereference the 'result' pointer and store NULL to it. Thus, our checking for a non-null 'result' pointer before reflecting that write in the instrumentation was trivially dead. Remove it. Third, the interceptor was marking the write to the actual dirent struct by looking at the entry pointer, but nothing in the spec requires that the dirent struct written is actually written into the entry structure provided. A threadlocal buffer would be just as conforming, and the spec goes out of its way to say the pointer to the *actual* result dirent struct is stored into *result, so *that* is where the interceptor should reflect a write occuring. This also obviates the need to even consider whether the 'entry' parameter is null. Fourth, I got to the bottom of why nothing at all worked in readdir64_r -- the interceptor structure for dirent64 was completely wrong in that it was the same as dirent. I fixed this struct to be correct (64-bit inode and 64-bit offset! just a 64-bit offset isn't enough!) and added several missing tests for the size and layout of this struct. llvm-svn: 186109
