1 2003-01-06 Martin Baulig <martin@ximian.com>
3 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
4 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
6 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
8 * debug.c: Move must_send_finished var declaration out of #if win32
9 block (this fixes the build on win32)
11 2003-01-05 Martin Baulig <martin@ximian.com>
13 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
14 this is used when we're running inside the Mono Debugger
15 (mono_debugger_wait): Put the waiting code into a function of its own.
17 * mono.c (main): Call mono_debugger_jit_exec() instead of
18 mono_jit_exec() if we're running inside the Mono Debugger.
20 2003-01-05 Martin Baulig <martin@ximian.com>
22 * debug.h (MonoDebugFormat): Added
23 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
24 we're running inside the Mono Debugger prior to the args parsing.
26 2003-01-04 Martin Baulig <martin@ximian.com>
28 * debug.c (release_symbol_file_table): Only call this if we're
29 actually modifying the symbol tables.
30 (mono_debug_open): Always set the `mono_debugger_class_init_func'
31 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
33 2003-01-03 Martin Baulig <martin@ximian.com>
35 * debug.c: Disable the mono debugger stuff on Windows.
37 2003-01-03 Martin Baulig <martin@ximian.com>
39 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
40 function. This is called from the breakpoint trampoline to signal
41 the debugger and wait until it has reload the symbol tables.
43 * trampoline.c (get_breakpoint_trampoline): Call the new
44 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
45 trampoline just before the breakpoint.
47 2002-12-31 Martin Baulig <martin@ximian.com>
49 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
50 field to point to the MonoGlobalSymbolTable.
52 2002-12-30 Martin Baulig <martin@ximian.com>
54 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
55 This variable now specifies that the symbol tables have been
56 modified after the last notification has been send. The debugger
57 uses this flag to check whether it needs to reload the symbol
59 (debugger_compile_method): Just send a notification to the
60 debugger, but don't set the modified flag. It may or may not be
61 set when the debugger gets the notification - depending on whether
62 the JIT compilation added a new method to the symbol tables.
64 2002-12-30 Martin Baulig <martin@ximian.com>
66 * debug.c (debugger_compile_method): This is a wrapper around
67 mono_compile_method() which always sends a notification to the
70 2002-12-30 Martin Baulig <martin@ximian.com>
72 * debug.c: Reload the symbol file table before sending the
73 notification event to the debugger.
74 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
76 2002-12-31 Martin Baulig <martin@ximian.com>
78 * debug.c: Propertly lock everything and avoid race conditions.
79 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
81 2002-12-31 Duncan Mak <duncan@ximian.com>

84 declaring ret at the top of the function.
86 2002-12-30 Martin Baulig <martin@ximian.com>
88 * debug.c: When running under the mono debugger, create a special
89 debugger thread; always protect the symbol tables with a mutex.
91 2002-12-28 Martin Baulig <martin@ximian.com>
93 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
94 incremented each time one of the symbol tables is modified.
96 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
98 * jit.c: fix LDELEMA implementation here as well.
100 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
102 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.

112 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
114 * jit.c (mono_analyze_stack): call the utility function
115 mono_field_from_token to avoid code duplication.
117 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
119 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
121 * x86.brg (stmt): POP floating point stack correctly
123 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
125 * emit-x86.c (arch_emit_prologue): don't save caller saved
128 * exception.c (x86_unwind_native_frame): support exceptions inside
129 native code using gcc generated exception tables (-fexception).
131 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
133 * exception.c: include some code from Zoltan Varga, but modified
136 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
138 * exception.c: massive code cleanups. The code is still
139 architecture dependent, but it should be now possible to reuse the
140 complex parts for other architecture.
142 2002-11-15 Dick Porter <dick@ximian.com>
144 * jit.c: Pass the attach callback to mono_runtime_init().
146 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>

150 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
152 * x86.brg (reg): fix bug #2721
154 * jit.c (mono_runtime_install_handlers): impl.
156 2002-10-17 Martin Baulig <martin@gnome.org>
158 * debug.c (mono_debug_add_method): Make this actually work if we don't
159 have any lifetime information.
161 2002-10-15 Martin Baulig <martin@gnome.org>
163 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
165 * debug.c (generate_line_number): Small fix to make this actually
166 work for more complex things.
168 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
170 * x86.brg (freg): use fprem instead of fprem1
172 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
174 * jit.c (ves_array_element_address): added check for out of range index

185 2002-09-27 Martin Baulig <martin@gnome.org>
187 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
189 2002-09-27 Dick Porter <dick@ximian.com>
191 * mono.c: Tell glib what the program name is, by passing it the
192 name of the managed file we're executing
194 2002-09-26 Martin Baulig <martin@gnome.org>
196 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
197 trampoline into the vtable, also use it for non-virtual methods,
198 remove the breakpoint when done.
200 2002-09-26 Martin Baulig <martin@gnome.org>
202 * debug.c (debug_load_method_lines): Block SIGCHLD while running
205 2002-09-26 Martin Baulig <martin@gnome.org>
207 * debug.c: Reworked the whole debugging stuff. We have now one
208 single `mono_debug_handle' which keeps a hashtable of
209 `AssemblyDebugInfo's (which may have different debugging formats).
210 The AssemblyDebugInfo is now created when the assembly is loaded,
211 but never when adding a class/type.
213 * mono.c: Initialize debugging stuff after corlib and the assembly
216 2002-09-25 Martin Baulig <martin@gnome.org>
218 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
219 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
221 (DebugMethodInfo): Removed `line_numbers'.
223 * debug.c: Reworked the line number generation; we're now using
224 the MonoDebugLineNumberEntry try for all debugging formats. This
225 type also includes the line number and IL offset, this allows the
226 JIT to produce better line number info: we only emit line number
227 information for source lines which actually have code.
229 2002-09-25 Martin Baulig <martin@gnome.org>
231 * debug.h: Removed external declaration of all functions which
232 should only be called from the Mono Debugger and also made them
233 static. Since the debugger gets their address from the
234 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
237 2002-09-25 Martin Baulig <martin@gnome.org>
239 Improved breakpoint support, we can now dynamically insert and
240 remove breakpoints at runtime and when called from withing the
241 Mono Debugger, we're using a special breakpoint trampoline.
243 * debug.h (mono_method_has_breakpoint): New method to check
244 whether to insert a breakpoint for a method.
245 (mono_insert_breakpoint): New method to insert a breakpoint.
246 (mono_insert_breakpoint_full): New method to insert a breakpoint,
247 takes a MonoMethodDesc.
248 (mono_remove_breakpoint): New method to remove a breakpoint.
250 * debug.c (mono_debugger_insert_breakpoint): New function for the
251 debugger. Should only be called from the debugger.
252 (mono_debugger_remove_breakpoint): Likewise.
254 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
256 * trampoline.c (get_breakpoint_trampoline): New static function to
257 create a special breakpoint trampoline for the debugger.
258 (x86_magic_trampoline): If we're running inside the Mono Debugger
259 and a breakpoint was requested for the method, generate a special
260 breakpoint trampoline.
262 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
263 to insert a breakpoint.
264 (mono_debug_last_breakpoint_address): Removed.
265 (match_debug_method): Removed, use mono_method_has_breakpoint().
267 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
269 * jit.c: reorder mono_runtime_cleanup () call since it needs the
270 engine still fully working.
272 2002-09-24 Martin Baulig <martin@gnome.org>
274 * debug.c (mono_debug_open): When we're invoked from inside the
275 Mono Debugger, set mono_debugger_class_init_func (exported in
276 metadata/class.c) to mono_add_type().
277 (mono_add_type): Call mono_debug_symfile_add_type().
279 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
281 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
282 Run finalize on domain cleanup.
283 * mono.c: call setlocale ().
284 * trampoline.c: clearer error message for invalid trampoline.
286 2002-09-21 Martin Baulig <martin@gnome.org>
288 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
289 instead of writing a byte blob.
290 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
291 (mono_debug_add_method): Incrementally add the new method to the symbol
294 * exception.c (arch_handle_exception): If we have debugging support,
295 call mono_debugger_update_symbol_file_table () as well.
297 2002-09-20 Martin Baulig <martin@gnome.org>
299 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
300 the size of the variable.
302 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
304 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
305 iterations if we visit blocks in reverse order.
307 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
309 * jit.c (mono_analyze_stack): cleaup of the array code
311 * exception.c: added patch from Julio Merno to fix bug #30048

315 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
317 * x86.brg (LDELEMA): use x86_lea
319 2002-09-06 Martin Baulig <martin@gnome.org>
321 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
322 If you were getting random crashes when using the JIT with debugging
323 turned on, this fixes it.
325 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
327 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
329 2002-09-05 Martin Baulig <martin@gnome.org>
331 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
332 which is read by the debugger.
334 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

337 to reduce exported symbols.
339 2002-09-03 Martin Baulig <martin@gnome.org>
341 * debug.c (free_method_info): Make this actually work.

345 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
346 * debug-dwarf2-plus.c: Removed.
348 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
349 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
350 `mono_symfile' to `symfile'.
352 * debug.c (mono_debug_open): Replaced the assembly argument with a
353 file name argument; you can now call this before loading the assembly.
354 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
355 we now use MonoSymbolFileLineNumberEntry's and a separate address array
356 instead; splitted out all MonoSymbolFileLineNumberEntry code into
357 debug_generate_il_offsets() and debug_update_il_offsets().
358 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
359 created when reading the symbol file or from debug_load_method_lines().
360 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
362 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
363 looking up an address.

381 * debug.c: The mono symbol file is installed together with the assembly
382 it belongs to and it's used on a per-image basis.
384 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
386 * mono.c: don't use the cil-coff header outside of the loader.
388 2002-08-27 Martin Baulig <martin@gnome.org>
390 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
391 to use global variables for this since they're stored in a core file.

393 (mono_debugger_symbol_file_table): New global variable.
394 (mono_debugger_update_symbol_file_table): New global function to update

399 * trampoline.c (mono_generic_trampoline_code): New global variable.
400 (arch_create_jit_trampoline): Use the new global variable to store the
401 generic trampoline code instead of using a static one. This allows the
402 debugger to access this variable to check whether a method is a trampoline.
404 * debug.h (mono_generic_trampoline_code): Added external declaration.
406 2002-08-27 Martin Baulig <martin@gnome.org>
408 * debug.c (MonoDebugHandle): Moved the method hash into the
409 AssemblyDebugInfo struct since we need to use a separate hash for each
412 * debug.c: Added special undocumented command line argument to create a
413 symbol file for IL files on-the-fly. In this case, we also need to create
414 the IL files and parse them.
415 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
417 2002-08-26 Martin Baulig <martin@gnome.org>

431 * mono.c (main): The `--debug' argument now knows about a new
432 debugging format `mono' which will be used to display source lines
435 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
436 which will be used when displaying backtraces. It reads a new

457 2002-08-19 Nick Drochak <ndrochak@gol.com>
459 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
460 the algebraic form we are using. This also eliminated a silly overflow
461 of the intermediate result that was causing troubles.
463 2002-08-16 Nick Drochak <ndrochak@gol.com>
465 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
468 2002-08-15 Nick Drochak <ndrochak@gol.com>
470 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
471 will not fit in 64 bits. Fixes bug #27375.

486 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
488 * exception.c (arch_handle_exception): simply return and let the
489 libpthread/kernel restore the context. This should work on recent
490 versions of linuxthreads.
492 * jit.c (mono_runtime_install_handlers): switch back to use
493 sigaction from libpthreads. As long as this does not make problems
494 we should use this instead of syscall.
496 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
498 * jit.c: removed the createdelegate icall
499 (mono_analyze_stack): special case Array::Address()

504 mono_get_lmf_addr relocatable.
505 (arch_jit_compile_cfg): do not waste memory
506 (arch_jit_compile_cfg): use a mempool to store native code. This
507 improves locality of code.

511 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
513 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
515 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
516 than one page, it's necessary to allocate memory incrementally,
517 in page-size steps, performing stack-touch every time.
518 Also added LOCALLOC(CONST_I4) implementation.
520 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
522 * jit.c (mono_get_runtime_method): code cleanup
524 * x86.brg: we do not need to save EAX/ECX/EDX in stmt:

936 2002-05-21 Martin Baulig <martin@gnome.org>
938 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
939 file for all assemblies. Currently, the JIT doesn't put all methods
940 from a single assembly into a continuous region of memory. We were

942 GDB's symbol tables get messed up when it reads more than one such file.

1205 * x86.brg (stmt): removed stmt: STIND_I4 (addr, coni4) rule
1206 because it slows down performance.

1330 (arch_end_invoke): we now pass a MonoMethod as first parameter and
1331 use arch_method_call_message_new() to access the stack.
1332 (arch_end_invoke): wait until we really finished processing
1333 (async_invoke_abort): notify all listeners, not only a
1336 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1393 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1394 (AssemblyDebugInfo): Added `format'.
1396 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1397 this allows us choose the format on a per-assembly basis.

1412 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1413 numbers, we still need to generate the IL offsets here. Emit line numbers
1414 for `prologue_end_offset' (the first line of actual code) and
1415 `epilogue_begin_offset' (the line of the method's closing brace).
1416 Don't crash if cfg->bblocks [i].forest is NULL.
1417 (mono_debug_add_method): Don't crash if we don't have line numbers.
1418 Initialize the newly added fields.
1420 * debug-stabs.c: Record first and last line, emit filename info at the
1421 beginning of the stab file, gdb ignores the types otherwise.
1423 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1424 emit line number info for the first and last line.
1426 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1428 * invoke.c (arch_create_delegate_trampoline): impl.
1430 Thu Mar 28 11:58:53 CET 2002 Paolo Molaro <lupus@ximian.com>

1435 * debug.h, debug.c: constify char* argument.
1437 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1457 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
1460 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1461 we don't have line number information. Use `minfo->method_info.this_offset'
1462 instead of hardcoding 8.
1464 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1465 line number information.

1490 2002-03-23 Martin Baulig <martin@gnome.org>
1492 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1493 to do it before the X86_CMP.
1494 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1495 (reg: CLT (lreg, lreg)): Likewise.
1496 (reg: CLT_UN (lreg, lreg)): Likewise.

1526 removed everything which is already in MonoDebugMethodInfo.
1528 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.
1529 (mono_debug_make_symbols): Don't open the file or call as, this is done in the

1565 2002-03-17 Martin Baulig <martin@gnome.org>
1567 * debug.c (mono_debug_get_type): Recursively call this for all function members
1569 (mono_debug_add_method): Don't mangle function names, this must be done by the
1570 debugger backend if the debugging format needs mangled names.
1572 * debug-dwarf2.c: Improved support for classes, added member functions.
1574 2002-03-16 Martin Baulig <martin@gnome.org>
1576 * debug.c (mono_debug_get_type): Recursively call this for all members and
1577 parent classes of a class type.
1579 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1580 since GDB doesn't like Java very much.
1582 2002-03-16 Martin Baulig <martin@gnome.org>
1584 * debug-dwarf2.c: Added support for enums.
1586 2002-03-15 Martin Baulig <martin@gnome.org>

1607 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1609 (mono_debug_open_file): Added MonoDebugFormat argument.
1610 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1611 this function from GDB. It's now safe to call this function multiple times;
1612 it'll always write a complete debugging file.
1614 * debug.c: Splitted this file into a general part which remains in this file
1615 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1616 All public functions now call a corresponding format specific function.
1618 * debug.c: The following changes are private to debug.c:
1619 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1620 (record_line_number, debug_generate_method_lines): New private functions.
1621 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1622 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1623 mono_debug_open_assembly_dwarf2).
1624 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1625 now safe to call this function multiple times.
1626 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1627 returns an unique index for this type. It's used to ensure that we only write
1628 each class once to the debugging file.
1629 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1630 data structure, but don't directly write to the debugging file. This is done
1631 later from mono_debug_write_assembly().
1633 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1634 debugging output. Call mono_debug_close() on cleanup if necessary.
1636 2002-03-14 Martin Baulig <martin@gnome.org>
1638 * debug-private.h: New private header file.
1640 * debug-stabs.c: Added the stabs type generation stuff which was
1641 previously in debug.c.
1643 * debug-dwarf.c: Started to implement type support. We're currently
1644 only writing this most basic types to the dwarf file, but this will
1647 2002-03-13 Martin Baulig <martin@gnome.org>
1649 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1650 debugging code. They're now in CVS, but not yet used anywhere.
1652 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1654 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1655 macros, included new delegate code from Daniel Stodden.
1658 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1660 * jit.c: verify that corlib and runtime are in sync.
1662 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1664 * emit-x86.c, jit.c: use the debug-helpers facilities to
1665 describe and match a method when debugging.
1667 2002-03-10 Martin Baulig <martin@gnome.org>
1669 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1670 output, put a nop instruction at the start of all functions so that
1671 the adresses won't change when using --debug.
1673 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1674 the bytecode area, stabs needs a line number in the .il file. Use the
1675 new info->moffsets to get the line number.
1676 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1677 `moffsets' is an array of `total_lines' fields (total number of lines
1678 in the .il file); for each line in the .il field, this array contains
1679 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1680 of a method and 0 otherwise.
1681 (debug_load_method_lines): Read the whole .il file and initialize the
1682 info->moffsets field.
1684 2002-03-09 Martin Baulig <martin@gnome.org>
1686 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1687 the unnecessary CDQ instruction.
1689 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1691 * jit.c (mono_analyze_stack): only load addresses of value types
1692 on the runtime stack.
1694 2002-03-07 Duncan Mak <duncan@ximian.com>
1696 * Makefile.am: A small patch fixing errors in vpath-based builds
1697 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1698 committed for Daniel Stodden <stodden@in.tum.de>.
1700 Thu Mar 7 17:22:52 CET 2002 Paolo Molaro <lupus@ximian.com>

1704 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1706 * x86.brg (SAVE_LFM): bug fix: patch the saved IP because we
1707 realloc that code sometimes!
1709 * emit-x86.c (mono_compute_branches): support several types of
1712 2002-03-06 Dietmar Maurer <dietmar@ximian.com>
1714 * x86.brg: impl. MUL_OVF_UN (reg, reg)

2305 2001-09-19 Dietmar Maurer <dietmar@ximian.com>
2307 * x86.brg: added more floating point grammar
2309 * testjit.c (mono_compile_method): make local offsets negative
2311 * x86.brg: added some floating point trees
2313 * testjit.c (mono_compile_method): arguments on the runtime
2314 stack are at least 4 bytes
2316 * x86.brg: partly implemented 8,16 bit integers
2318 * testjit.c (get_address): mark basic blocks
2320 2001-09-18 Dietmar Maurer <dietmar@ximian.com>
2322 * x86.brg: added some rules to optimize code
2324 * testjit.c (get_address): use a binary search to get the address
2325 (main): added an option to debug the jit (-d)
2327 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2329 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2331 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2333 * testjit.c (mono_compile_method): Provide better error reporting.
2335 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2337 * testjit.c (tree_get_address): impl. to fix address bug
2338 (tree_get_address): make sure that we can only jump to the first
2339 instruction of a tree.
2341 * x86.brg: emit real code for calls
2343 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2345 (mono_compile_method): reversed argument order
2347 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2349 * x86.brg (stmt): don't emit unnecessary register moves
2351 * testjit.c (tree_allocate_regs): free registers earlier
2353 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
2355 * x86.brg: branch addresses are now resolved
2357 * testjit.c (compute_branches): compute address of branches
2359 * x86.brg: emit real x86 instructions
2361 * testjit.c: call objdump to disassemble the output
2363 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2365 * x86.brg: use the right offsets to access local variables
2368 * emit-x86.c: only save/restore callee saved registers if they are
2371 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2373 (mono_compile_method): changed the tree for mothod calls
2380 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2382 * x86.brg: Use Unix assembly syntax.
2384 * emit-x86.c: support code, should be moved
2386 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2387 inefficient at appends.
2389 * Renamed `create_new_leave' to `create_new_leaf'
