Fixed portability bugs in neg and not opcodes. 2001-09-24 Dietmar Maurer * interp.c (ves_exec_method): LDC_I4: 8bit constants are signed (ves_exec_method): bug fix for NOT/NEG (main): fix bug in parameter parsing 2001-09-23 Dick Porter * Makefile.am (mint_LDADD): rename PTHREAD_LIBS to THREAD_LIBS 2001-09-23 Dick Porter * interp.c (main): Do some thread setup and cleanup around the call to ves_exec() 2001-09-21 Dick Porter * Makefile.am (mint_LDADD): Added PTHREAD_LIBS to the link line Thu Sep 20 16:32:42 CEST 2001 Paolo Molaro * interp.c: implemented some more opcodes: calli, rem.un, shr.un, conv.u, cpobj, stobj, conv.r.un, conv.ovf.i1.un, conv.ovf.i2.un, conv.ovf.i4.un, conv.ovf.i8.un, conv.ovf.i.un, conv.ovf.u1.un, conv.ovf.u2.un, conv.ovf.u4.un, conv.ovf.u8.un, conv.ovf.u.un. Fix some 64 bit issues in the array element access code and a small bug. Throw an exception on index out of range instead of asserting. Throw an exception on a NULL array instead of dying. Stomped a memory corruption bug (.cctor methods were freed after executing them, but they are stores in MonoClass now...). Added a simple facility to invoke the debugger when a named function is entered (use the cmdline option --debug method_name). * interp.h: fix 64 bit issue. Tue Sep 18 13:21:33 CEST 2001 Paolo Molaro * interp.c: fix some 64 bit issues. Safer support for delegates. 2001-09-12 Miguel de Icaza * interp.c (ves_exec_method): implement conv.u8 opcode.

Fixes to do signed compares when needed. Change C++ comments into C. Implemented cgt, clt. Added --opcode-count cmdline switch. 2001-08-28 Dietmar Maurer * interp.c (ves_exec_method): better check for value types (get the class to detect if we have a value type), implemented CEE_CONV_U1, CEE_CONV_U2, CEE_CEQ Mon Aug 27 21:30:30 CEST 2001 Paolo Molaro * interp.c: warn and exit when Main () expects the cmdline arguments instead of creashing. Mon Aug 27 20:16:37 CEST 2001 Paolo Molaro * interp.c: merge isinst/castclass handling. Hopefully implement the right semantics for handling callvirt correctly (changes here and there to support it). Integrate bugfix from Dietmar quickly so he needs to handle the cvs conflict:-) Mon Aug 27 12:20:32 CEST 2001 Paolo Molaro * interp.c: fix compilation and updates for changes in metadata/. 2001-08-26 Miguel de Icaza * interp.c (main): Add option handling for the interpreter, support the `--trace' option.

Print the arguments in the stack trace and the name of the exception. Sat Aug 25 15:56:03 CEST 2001 Paolo Molaro * interp.c: Implemented some opcodes: starg.s, ldobj, isinst, ldarg, starg, ldloc, ldloca, stloc, initobj, cpblk, sizeof.

Completed rethrow handling Tue Aug 21 18:56:19 CEST 2001 Paolo Molaro * interp.c: new macro INIT_FRAME() to properly initialize a MonoInvocation. Fixed a couple of buglets in exception code: increase stack pointer when pushing the exception for catch blocks, initialize frame->ex_handler to NULL, correctly try all the catch blocks (don't incorrectly fallback on filter handling). Added a couple more checks where we may need to throw an exception. Added more exception creation functions. Changed stackval_from_data() to take the target stackval as argument. Implemented a couple more opcodes. * interp.h: prepare stackval for value type code. 2001-08-21 Miguel de Icaza * Makefile.am (mint_LDADD): Renamed interpreter to mint. 2001-08-21 Dietmar Maurer * interp.c (get_named_exception): use the right constructor.

Changed interncal calling convnetion over to MonoInvocation, to support exceptions, walking the stack back and forward and passing the 'this' pointer separately (remove the cludges required before to pass this on the stack). Use alloca heavily for both local vars and a copy of the incoming arguments. Init local vars to zero. Simplify stackval_from_data() and stackval_to_data() to only take a pointer instead of pointer + offset. Implement a few exceptions-related opcodes and the code to run finally, fault and catch blocks as well as a stack trace if no handler is found. 2001-08-16 Alex Graveley * Makefile.am (mono_int_LDADD): Link with ../../libffi/libffi.a instead of ../../libffi/.libs/libffi.a. 2001-08-10 Dietmar Maurer * interp.c (ves_exec_method): impl CASTCLASS * icall.c: moved the internal call stuff to this file * interp.c (ves_exec_method): impl.
