[ i don't recall seeing answers to this. ]
I'd like to use gcc 2.95.3 to generate 64 bit executables under
NetBSD's sparc64 gcc obviously creates these and I was
wondering what, if any, problems there would be if I created
a gcc with a target of sparcv9-sun-solaris2.8?
If I don't use optimization will the 2.95.3 compiler work? Do
I need to add additional flags to compiles?
Since NetBSD/sparc64 is ELF I'm assuming it would have similar
issues to Solaris.
netbsd/sparc64's compiler is heavily hacked from the FSF version,
mostly by mycroft, to fix several serious bugs, leaving only several
dozen remaining. :-) i wouldn't trust the 2.95.3, or 3.0, from FSF
to create 64 bit sparc binaries safely. i'm told that "red hat" gcc
(the `2.96' thing) supposedly works well for sparc64 (but i was
unable to bootstrap it), and that gcc-current should (but i was also
unable to bootstrap it.)
64 bit & sparc & gcc doesn't seem to mix well right now.
