twfowler, Those old DOS program run fine on those old 286 machines. They did not have all the bloat of today's code. C

Re: Imagine running old DOS programs with all the memory being addressed all cached on the die... That's basically how SPEC benchmarks are... "optimized". A SPEC special compiler is written to parse out SPEC routines, and the compiler substitutes pre-written, hand optimized assembler code for normal compiler output. The optimized assembler is a block of code that has been written to fit in, and stay resident in, the cache of the target CPU. It can be written to not perform any runtime error checking, which is dangerous, but produces good scores.
