#### 3.17.49 VAX Options

These ‘`-m`’ options are defined for the VAX:

`-munix`

  Do not output certain jump instructions (`aobleq` and so on) that the Unix assembler for the VAX cannot handle across long ranges.

`-mgnu`

  Do output those jump instructions, on the assumption that the GNU assembler is being used.

`-mg`

  Output code for G-format floating-point numbers instead of D-format.
