VAX Options - Using the GNU Compiler Collection (GCC)

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.
