I masked all the registers when generating instructions, and with the float registers renumbered all of the test/internal tests pass. Kaffe itself won't yet load, however. This solution is obviously a hack; the correct fix is probobly to fix register.c to not assume that regno is an index into reginfo. Unrelated question to the peanut gallery: currently the stack trace I get when Kaffe is loading (an "Internal error: caught an unexpected exception.") goes all the way back to java.lang.VMThrowable.fillInStackTrace(VMThrowable.java:native). Is this just a symptom of an exception being thrown early, or is this yet another problem with the MIPS backend? - -- Casey Marshall || [EMAIL PROTECTED] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) Comment: Processed by Mailcrypt 3.5.7 <http://mailcrypt.sourceforge.net/> iD8DBQFASQvdgAuWMgRGsWsRAoMrAKCHnDxQqb4F3Y/lXeTd5w7jUrHQxACeLKNP Sk21s4RmhYzHAntbg+My50s= =wQLR -----END PGP SIGNATURE----- _______________________________________________ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
