+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.
+The same assembler is used for all target operating systems and architectures.
+The GOOS and GOARCH environment variables set the desired target.
+
+Flags:
+
+	-D name[=value]
+		Predefine symbol name with an optional simple value.
+		Can be repeated to define multiple symbols.
+	-I dir1 -I dir2
+		Search for #include files in dir1, dir2, etc,
+		after consulting $GOROOT/pkg/$GOOS_$GOARCH.
+	-S
+		Print assembly and machine code.
+	-V
+		Print assembler version and exit.
+	-debug
+		Dump instructions as they are parsed.
+	-dynlink
+		Support references to Go symbols defined in other shared libraries.
+	-gensymabis
+		Write symbol ABI information to output file. Don't assemble.
+	-o file
+		Write output to file. The default is foo.o for /a/b/c/foo.s.
+	-shared
+		Generate code that can be linked into a shared library.
+	-spectre list
+		Enable spectre mitigations in list (all, ret).
+	-trimpath prefix
+		Remove prefix from recorded source file paths.
+
+Input language:
+
+The assembler uses mostly the same syntax for all architectures,
+the main variation having to do with addressing modes. Input is
+run through a simplified C preprocessor that implements #include,
+#define, #ifdef/endif, but not #if or ##.
+
+For more information, see https://golang.org/doc/asm.
