- Why would assembly code prevent old programs from being recompiled???
- When Tandem went from proprietary processors a few years back, we used
- an "accellerator" which basically took an _object_ file as input, and
- produced an optimized MIPS risc object, which runs just fine (way better
- than running in "code interpretation mode," which is another way to run
- old software on new hardware, that is, in emulation mode). Fact is, as
- the MIPS CPUs were so much faster than the earlier CPUs, even running
- in emulation mode was faster than running on the old iron... Although
- I haven't heard of such a beast, it should be possible to develop a
- compiler that reads M68K assembler source and produces a risc object,
- why not?
