(The Motorola numbers were taken from the last published numbers in a SPEC newsletter for a 25MHZ box). Harris CCG compilers are a family of highly optimizing compilers (C, Fortran, and Ada) available for the entire line of Harris Night Hawk realtime computer systems (OK, OK, I apoligize for the blatant plug). Besides standard optimizations we have also put a lot of work into things that greatly benefit RISC architectures in general and the 88k in particular. It is also worth noting that many of the above times are better than the best numbers for 25MHZ MIPS workstations (most of the double precision intensive benchmarks do much better on MIPS - this should not suprise anyone, it certainly does not suprise me). Disclaimer: No these are not the compilers we are shipping in our current release, they are our inhouse development versions which will eventually filter out into future releases. We certainly hope that the compilers we eventually release will do even better. -- ====================================================================== domain: tahorsley@csd.harris.com USMail: Tom Horsley uucp: ...!uunet!hcx1!tahorsley 511 Kingbird Circle Delray Beach, FL 33444 +==== Censorship is the only form of Obscenity ======================+ | (Wait, I forgot government tobacco subsidies...) | +====================================================================+
