3.19.56 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.
