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

429 * interp.c, interp.h: added support code to create exceptions.
430 Changed interncal calling convnetion over to MonoInvocation, to support
431 exceptions, walking the stack back and forward and passing the 'this'
432 pointer separately (remove the cludges required before to pass this on the
433 stack). Use alloca heavily for both local vars and a copy of the incoming
434 arguments. Init local vars to zero.
435 Simplify stackval_from_data() and stackval_to_data() to only take a pointer
436 instead of pointer + offset.
437 Implement a few exceptions-related opcodes and the code to run finally, fault and
438 catch blocks as well as a stack trace if no handler is found.

547 deal with void functions. Fixed constructor to leave the object on
550 Thu Jul 26 13:24:51 CEST 2001 Paolo Molaro <lupus@ximian.com>
552 * interp.c: ves_exec_method () doesn't take a MonoImage arg
553 anymore. Use the method cache in MonoImage. Updates to
554 mache recent changes in metadata.
555 Fix newobj code to use new metadata features. Call the class
556 constructor after allocationg the object. Implemented load field
557 and store field opcodes (the support functions need to be finished).
559 Tue Jul 24 16:51:09 CEST 2001 Paolo Molaro <lupus@ximian.com>
561 * interp.c, hacks.h: moved a few ugly macros out of the code.
562 Implemented switch opcode.

566 * interp.c (newobj): Added function to handle newobj opcode.
568 2001-07-18 Miguel de Icaza <miguel@ximian.com>
570 * interp.c (ves_exec_method): Make the interpreter abort with more
571 information than it currently does.
573 Enable the slow processor, as it is easier to debug.
575 Sun Jul 15 17:50:23 CEST 2001 Paolo Molaro <lupus@ximian.com>
578 * interp.c: use new mono_get_method () function to get the complete
579 info on a method invocation: we support now method invocation with
580 multiple (or zero) simple arguments and with or without a return value.
581 Implement also a couple more opcodes.
