[asan] adding support of 32-bit address sanitizer for MIPS Summary: The patch supports both the clang cross-compiler and native compiler Patch by Kumar Sukhani <Kumar.Sukhani@imgtec.com> Test Plan: Kumar had the following asan test results when compiled on a MIPS board: Expected Passes : 96 Expected Failures : 2 Unsupported Tests : 84 Unexpected Passes : 4 Unexpected Failures: 19 The list of unexpected failures can be found in the review.

#if defined(__x86_64__) || defined(__mips__)
[asan] Include <sys/stat.h> if __x86_64__ is defined struct stat defined in <asm/stat.h> is incorrect for x32. <asm/stat.h> is included to get struct __old_kernel_stat. But struct __old_kernel_stat isn't used for x86-64 nor x32. This patch includes <sys/stat.h> instead of <asm/stat.h> and comments out size check of struct __old_kernel_stat for x86-64. Patch by H.J.

[sanitizer] Change the way we use certain linux kernel headers. Some linux headers are broken on older kernels. Instead of depending on the constants and types from such headers directly, we provide our own definitions and then verify them with compile-time assertions. This makes the dependency on the headers test-only and would allow switching to some other way of testing on older kernels, or even disable the tests as the last resort (after all, kernel interfaces are supposed to be stable). llvm-svn: 195427

[sanitizer] [SystemZ] Add/fix kernel and libc type definitions. This is the first part of upcoming asan support for s390 and s390x. Note that there are bits for 31-bit support in this and subsequent patches - while LLVM itself doesn't support it, gcc should be able to make use of it just fine.
