// 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".
