3.19.50 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.

+ -mlra +
-mno-lra

Enable Local Register Allocation. This is still experimental for the VAX, so by default the compiler uses standard reload.
