[PATCH] D64388: Explicitly define __STDC_FORMAT_MACROS for PRIu64

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: compiler-rt/trunk/lib/gwp_asan/guarded_pool_allocator.cpp:14
+// RHEL creates the PRIu64 format macro (for printing uint64_t's) only when this
+// macro is defined before including <inttypes.h>.
+#ifndef __STDC_FORMAT_MACROS
----------------
How do you know it wasn't included before somewhere, by some previous header?
This i think normally should be solved by adding `-D__STDC_FORMAT_MACROS` to compile command.
