Subject: Re: compiling cmulisp From: Erik Naggum <firstname.lastname@example.org> Date: 1998/10/24 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * Raymond Toy <firstname.lastname@example.org> | However, with CMUCL, recompiling the compiler *changes* the compiler | that's doing the compiling. For example, there's a variable in CMUCL | that essentially is an enum for all of the recognized types. If you add | a new type, such as (signed-byte 8), this needs to be placed in the enum. | However, when you compile this up, it changes that variable in the | compiler that's compiling the code, and the current compiler is totally | confused by that change because it's now wrong. this can't be true. COMPILE-FILE is explicitly required _not_ to pollute the execution environment, but (in some sense) write compiled code to a file for later loading. only if you cause expressions to be avaluated at compile-time should this affect the execution environment. I don't think anyone could reasonably be expected to do that with a variable if it has the effect you sketch; it's a (fixable) bug, not an inherent problem. (sorry for the belated response, ignore if no longer relevant.) #:Erik -- The Microsoft Dating Program -- where do you want to crash tonight?
