2016-03-25[sanitizer] Add memset, memmove, and memcpy to the common interceptorsDerek Bruening
Summary: Currently, sanitizer_common_interceptors.inc has an implicit, undocumented assumption that the sanitizer including it has previously declared interceptors for memset and memmove. Since the memset, memmove, and memcpy routines require interception by many sanitizers, we add them to the set of common interceptions, both to address the undocumented assumption and to speed future tool development. They are intercepted under a new flag intercept_intrin. The tsan interceptors are removed in favor of the new common versions. The asan and msan interceptors for these are more complex (they incur extra interception steps and their function bodies are exposed to the compiler) so they opt out of the common versions and keep their own.

2016-03-23[sanitizer] Add strnlen to the common interceptorsDerek Bruening
Summary: Adds strnlen to the common interceptors, under the existing flag intercept_strlen. Removes the now-duplicate strnlen interceptor from asan and msan. This adds strnlen to tsan, which previously did not intercept it. Adds a new test of strnlen to the sanitizer_common test cases.

2016-03-21[sanitizer] Add strchr* to the common interceptorsEvgeniy Stepanov
Adds strchr, strchrnul, and strrchr to the common interceptors, under a new common flag intercept_strchr. Removes the now-duplicate strchr interceptor from asan and all 3 interceptors from tsan. Previously, asan did not intercept strchrnul, but does now; previously, msan did not intercept strchr, strchrnul, or strrchr, but does now. http://reviews.llvm.org/D18329 Patch by Derek Bruening! git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@263992 91177308-0d34-0410-b5e6-96231b3b80d8
2016-03-11[sanitizer] Add strlen to the common interceptorsAlexey Samsonov
Summary: Adds strlen to the common interceptors, under a new common flag intercept_strlen. This provides better sharing of interception code among sanitizers and cleans up the inconsistent type declarations of the previously duplicated interceptors. Removes the now-duplicate strlen interceptor from asan, msan, and tsan. The entry check semantics are normalized now for msan and asan, whose private strlen interceptors contained multiple layers of checks that included impossible-to-reach code. The new semantics are identical to the old: bypass interception if in the middle of init or if both on Mac and not initialized; else, call the init routine and proceed. Patch by Derek Bruening!

2015-09-16[MSan] Enable MSAN for aarch64Adhemerval Zanella
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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@247809 91177308-0d34-0410-b5e6-96231b3b80d8
