+// Symbolizer is intended to be used by both
+// AddressSanitizer and ThreadSanitizer to symbolize a given
+// address. It is an analogue of addr2line utility and allows to map
+// instruction address to a location in source code at run-time.
+//
+// Symbolizer is planned to use debug information (in DWARF format)
+// in a binary via interface defined in "llvm/DebugInfo/DIContext.h"
+//
+// Symbolizer code should be called from the run-time library of
+// dynamic tools, and generally should not call memory allocation
+// routines or other system library functions intercepted by those tools.
+// Instead, Symbolizer code should use their replacements, defined in
+// "compiler-rt/lib/sanitizer_common/sanitizer_libc.h".
