248 function is entered (use the cmdline option --debug method_name).
249 * interp.h: fix 64 bit issue.
251 Tue Sep 18 13:21:33 CEST 2001 Paolo Molaro <lupus@ximian.com>

412 * interp.c, interp.h: added support code to create exceptions.
413 Changed interncal calling convnetion over to MonoInvocation, to support
414 exceptions, walking the stack back and forward and passing the 'this'
415 pointer separately (remove the cludges required before to pass this on the
416 stack). Use alloca heavily for both local vars and a copy of the incoming
417 arguments. Init local vars to zero.
418 Simplify stackval_from_data() and stackval_to_data() to only take a pointer
419 instead of pointer + offset.
420 Implement a few exceptions-related opcodes and the code to run finally, fault and
421 catch blocks as well as a stack trace if no handler is found.

549 * interp.c (newobj): Added function to handle newobj opcode.
551 2001-07-18 Miguel de Icaza <miguel@ximian.com>
553 * interp.c (ves_exec_method): Make the interpreter abort with more
554 information than it currently does.
556 Enable the slow processor, as it is easier to debug.

561 * interp.c: use new mono_get_method () function to get the complete
562 info on a method invocation: we support now method invocation with
563 multiple (or zero) simple arguments and with or without a return value.
564 Implement also a couple more opcodes.
