9 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers

14 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
15 will not fit in 64 bits. Fixes bug #27375.

60 than one page, it's necessary to allocate memory incrementally,
61 in page-size steps, performing stack-touch every time.
62 Also added LOCALLOC(CONST_I4) implementation.
64 2002-07-27 Dietmar Maurer <dietmar@ximian.com>

439 `const char **args' argument.
441 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
442 `int verbose' argument and made it public.
443 (mono_jit_compile_class): New public function, moved the code to compile

480 2002-05-21 Martin Baulig <martin@gnome.org>
482 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
483 file for all assemblies. Currently, the JIT doesn't put all methods
484 from a single assembly into a continuous region of memory. We were
485 previously creating valid DWARF 2 files for this, but unfortunately
486 GDB's symbol tables get messed up when it reads more than one such file.
488 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

510 * debug.h (mono_debug_format): New global variable.
511 (MonoDebugFormat): Added MONO_DEBUG_FORMAT_NONE.

547 * jit.c (mono_find_final_block): make it work with mcs
549 * x86.brg: buf fix. if exception variable is allocated to a register.
551 * jit.c (mono_find_final_block): bug fix.
553 2002-05-15 Dietmar Maurer <dietmar@ximian.com>
555 * delegate.c (arch_end_invoke): fix bug #24653, simplified the
556 code using new runtime_invoke feature.
558 * jit.c (mono_analyze_flow): try blocks are followed by handler

580 store them as 32 bit integers.
581 (mono_analyze_stack): we need to generate a temporary var for
582 SHL/SHR because the tree allocator can fail otherwise
584 * exception.c (arch_handle_exception): EIP now points to the call
585 instruction, not to the instruction after the call. This fixes the
586 bug reported by Linus Upson (tests/exception8.cs)

590 * jit.c (mono_analyze_flow): always allocate the forest array

1168 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1169 now safe to call this function multiple times.
1170 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1171 returns an unique index for this type. It's used to ensure that we only write
1172 each class once to the debugging file.
1173 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1174 data structure, but don't directly write to the debugging file. This is done
1175 later from mono_debug_write_assembly().
1177 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1178 debugging output. Call mono_debug_close() on cleanup if necessary.

1191 2002-03-13 Martin Baulig <martin@gnome.org>
1193 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1194 debugging code. They're now in CVS, but not yet used anywhere.

1214 output, put a nop instruction at the start of all functions so that
1215 the adresses won't change when using --debug.
1217 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1218 the bytecode area, stabs needs a line number in the .il file. Use the
1219 new info->moffsets to get the line number.
1220 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1221 `moffsets' is an array of `total_lines' fields (total number of lines
1222 in the .il file); for each line in the .il field, this array contains
1223 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1224 of a method and 0 otherwise.
1225 (debug_load_method_lines): Read the whole .il file and initialize the
1226 info->moffsets field.
1228 2002-03-09 Martin Baulig <martin@gnome.org>
