References: Sender: Reply-To: cpf@lasspvax.UUCP (C. P. Footman) Followup-To: Distribution: net Organization: Theory Center (Cornell University) Keywords: By writing a c routine that declared about fifteen variables to be register, and then looking at the output of cc -S, I discovered that 4.2 bsd cc will use the first six (6) register variables. Is this documented anywhere on paper? It is not in man cc, as, or ld, and it is also not in any of the general stuff. It *is* in /usr/src/lib/pcc/mac2defs, but it took me a very long time to figure that out, and I don't think one should have to dig through the compiler source to find out what is legal in a language. Please MAIL me any comments on what an idiot I am. ____________________________________________________________________________ Courtenay Footman arpa: cpf@lnsvax Newman Lab. of Nuclear Studies usenet: cornell!lnsvax!cpf Cornell University --
