corresponds to a particular byte value [0..255]. For any
given byte value, if the value in the corresponding table
position is zero, the given character can be output directly.
If the table value is 1, the byte must be output as a \ooo
octal escape. If the tables value is anything else, then the
byte value should be output as a \ followed by the value
in the table. Note that we can use standard UN*X escape
sequences for many control characters, but we don't use
\a to represent BEL because some svr4 assemblers (e.g. on
the i386) don't know about that. Also, we don't use \v
since some versions of gas, such as 2.2 did not accept it. */
