"Simply stated, the VAX MACRO-32 compiler treats VAX MACRO-32 as a source
language to be compiled and creates native OpenVMS AXP object files
just as a FORTRAN compiler might. This task is far more complex than
a simple instruction-by-instruction translation because of fundamental
differences in the architectures, and because source code frequently
contains assumptions about the VAX architecture and the OpenVMS Calling
Standard on VAX systems.[3,4] The compiler must either transparently
convert these VAX dependencies to their OpenVMS AXP counterparts or inform
the user that the source code has to be changed."
Разумеется, это не простое перекомпилирование, но тем не менее.
