-// Consider we have an unaligned load/store of 4 bytes from address 0x...05.
-// AddressSanitizer will treat it as a 3-byte access to the range 05:07 and
-// will miss a bug if 08 is the first unaddressable byte.
-// ThreadSanitizer will also treat this as a 3-byte access to 05:07 and will
-// miss a race between this access and some other accesses to 08.
-// MemorySanitizer will correctly propagate the shadow on unaligned stores
-// and correctly report bugs on unaligned loads, but it may not properly
-// update and report the origin of the uninitialized memory.
-// For all three tools, replacing an unaligned access with a tool-specific
-// callback solves the problem.
-
-// Make sure uint16_t/uint32_t/uint64_t are defined.
