Message-ID: <2541@fortune.UUCP> Date: Tue, 14-Feb-84 22:29:15 EST Article-I.D.: fortune.2541 Posted: Tue Feb 14 22:29:15 1984 Date-Received: Fri, 17-Feb-84 03:32:31 EST References: <1649@rlgvax.UUCP> Organization: Fortune Systems, Redwood City, CA Lines: 17 On the PR1ME x50 series of machines, pointers to word-sized (16-bit) integers and larger things occupy 32 bits; pointers to characters (and bits) occupy 48 bits. This is a fundamental characteristic of the PR1ME instruction set architecture. Perhaps someone from Ga. Tech, which is alleged to have produced a C compiler for PR1ME or the Software Tools subsystem running on their machines, can confirm my strong suspicion that PR1ME C has TWO pointer sizes. -- Clay Phipps -- {allegra,amd70,cbosgd,dsd,floyd,harpo,hpda,ihnp4, megatest,nsc,oliveb,sri-unix,twg,varian,VisiA,wdl1} !fortune!phipps
