I want compiler-supported precise gc, with support for write barriers if generational gc is configured. However, first we want to get a working base system working. > + Is egcs gc-safe (*)? I don't know of any work to ensure this. Personally, given that it's not really an issue in practice, and given that precise gc should make the question moot (unless I'm thinking of some other definition of gc-safe), I don't see it as a priority. > + If egcs is used to create java shared libraries, will that both > accommodate ELF and a.out (FreeBSD's) format, or is that really > not even an issue at all? It's not an issue at this point. In the future, some linker support may be desirable for improved performance, but so far we make no demands on the linker or code generator between those needed for C++. --Per Bothner Cygnus Solutions bothner@cygnus.com http://www.cygnus.com/~bothner
