From 3c536954a67a883630f4a7513a27f02a892c3dcb Mon Sep 17 00:00:00 2001 From: Evgeniy Stepanov Date: Tue, 21 Oct 2014 21:08:13 +0000 Subject: [PATCH] [sanitizer] Fix build with _FILE_OFFSET_BITS=64. Sanitizer source is not affected by _FILE_OFFSET_BITS in general, but this one file must be built with 32-bit off_t. More details in the code. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@220328 91177308-0d34-0410-b5e6-96231b3b80d8 Signed-off-by: Max Filippov --- libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc | 8 ++++++++ 1 file changed, 8 insertions(+) --- a/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc +++ b/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc @@ -13,6 +13,14 @@ #include "sanitizer_platform.h" #if SANITIZER_LINUX || SANITIZER_MAC +// Tests in this file assume that off_t-dependent data structures match the +// libc ABI.
