// Nm lists the symbols defined or used by an object file, archive, or executable.
// Usage:
// go tool nm [options] file...
// The default output prints one line per symbol, with three space-separated
// fields giving the address (in hexadecimal), type (a character), and name of
// the symbol. The types are:
// T text (code) segment symbol
// t static text segment symbol
// R read-only data segment symbol
// r static read-only data segment symbol
// D data segment symbol
// d static data segment symbol
// B bss segment symbol
// b static bss segment symbol
// C constant address
// U referenced but undefined symbol
// Following established convention, the address is omitted for undefined
// symbols (type U).
// The options control the printed output:
// -n
// an alias for -sort address (numeric),
// for compatibility with other nm commands
// -size
// print symbol size in decimal between address and type
// -sort {address,name,none,size}
// sort output in the given order (default name)
// size orders from largest to smallest
// -type
// print symbol type after name
