Asm, typically invoked as “go tool asm”, assembles the source file into an object
file named for the basename of the argument source file with a .o suffix. The
object file can then be combined with other objects into a package archive.

# Command Line

Usage:

	go tool asm [flags] file

The specified file must be a Go assembly file.
