+Subject: [PATCH] compiler-rt: Undef _TIME_BITS along with _FILE_OFFSET_BITS on
+ linux
+
+On 32bit systems using 64bit time_t build fails because
+_FILE_OFFSET_BITS is undefined here but _TIME_BITS is still set to 64
+
+Fixes
+/usr/include/features-time64.h:26:5: error: "_TIME_BITS=64 is allowed
+ only with _FILE_OFFSET_BITS=64"
+| #   error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
+|     ^
+| 1 error generated.

+Upstream-Status: Submitted [https://reviews.llvm.org/D140812]
