1 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
3 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
5 2003-01-06 Martin Baulig <martin@ximian.com>
7 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
9 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
10 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
12 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
14 * debug.c: Move must_send_finished var declaration out of #if win32
15 block (this fixes the build on win32)
17 2003-01-05 Martin Baulig <martin@ximian.com>
19 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
20 this is used when we're running inside the Mono Debugger
21 (mono_debugger_wait): Put the waiting code into a function of its own.
23 * mono.c (main): Call mono_debugger_jit_exec() instead of
24 mono_jit_exec() if we're running inside the Mono Debugger.
26 2003-01-05 Martin Baulig <martin@ximian.com>
28 * debug.h (MonoDebugFormat): Added
29 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
30 we're running inside the Mono Debugger prior to the args parsing.
32 2003-01-04 Martin Baulig <martin@ximian.com>
34 * debug.c (release_symbol_file_table): Only call this if we're
35 actually modifying the symbol tables.
36 (mono_debug_open): Always set the `mono_debugger_class_init_func'
37 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
39 2003-01-03 Martin Baulig <martin@ximian.com>
41 * debug.c: Disable the mono debugger stuff on Windows.
43 2003-01-03 Martin Baulig <martin@ximian.com>
45 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
46 function. This is called from the breakpoint trampoline to signal
47 the debugger and wait until it has reload the symbol tables.
49 * trampoline.c (get_breakpoint_trampoline): Call the new
50 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
51 trampoline just before the breakpoint.
53 2002-12-31 Martin Baulig <martin@ximian.com>
55 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
56 field to point to the MonoGlobalSymbolTable.
58 2002-12-30 Martin Baulig <martin@ximian.com>
60 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
61 This variable now specifies that the symbol tables have been
62 modified after the last notification has been send. The debugger
63 uses this flag to check whether it needs to reload the symbol
65 (debugger_compile_method): Just send a notification to the
66 debugger, but don't set the modified flag. It may or may not be
67 set when the debugger gets the notification - depending on whether
68 the JIT compilation added a new method to the symbol tables.
70 2002-12-30 Martin Baulig <martin@ximian.com>
72 * debug.c (debugger_compile_method): This is a wrapper around
73 mono_compile_method() which always sends a notification to the
76 2002-12-30 Martin Baulig <martin@ximian.com>
78 * debug.c: Reload the symbol file table before sending the
79 notification event to the debugger.
80 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
82 2002-12-31 Martin Baulig <martin@ximian.com>
84 * debug.c: Propertly lock everything and avoid race conditions.
85 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
87 2002-12-31 Duncan Mak <duncan@ximian.com>
89 * debug.c (initialize_debugger_support): Fix build error by
90 declaring ret at the top of the function.
92 2002-12-30 Martin Baulig <martin@ximian.com>
94 * debug.c: When running under the mono debugger, create a special
95 debugger thread; always protect the symbol tables with a mutex.
97 2002-12-28 Martin Baulig <martin@ximian.com>
99 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
100 incremented each time one of the symbol tables is modified.
102 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
104 * jit.c: fix LDELEMA implementation here as well.
106 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
108 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.

118 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
120 * jit.c (mono_analyze_stack): call the utility function
121 mono_field_from_token to avoid code duplication.
123 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
125 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
127 * x86.brg (stmt): POP floating point stack correctly
129 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
131 * emit-x86.c (arch_emit_prologue): don't save caller saved
134 * exception.c (x86_unwind_native_frame): support exceptions inside
135 native code using gcc generated exception tables (-fexception).
137 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
139 * exception.c: include some code from Zoltan Varga, but modified
142 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
144 * exception.c: massive code cleanups. The code is still
145 architecture dependent, but it should be now possible to reuse the
146 complex parts for other architecture.
148 2002-11-15 Dick Porter <dick@ximian.com>
150 * jit.c: Pass the attach callback to mono_runtime_init().
152 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
154 * jit.c: display the domain name in trace output.
156 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
158 * x86.brg (reg): fix bug #2721
160 * jit.c (mono_runtime_install_handlers): impl.
162 2002-10-17 Martin Baulig <martin@gnome.org>
164 * debug.c (mono_debug_add_method): Make this actually work if we don't
165 have any lifetime information.
167 2002-10-15 Martin Baulig <martin@gnome.org>
169 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
171 * debug.c (generate_line_number): Small fix to make this actually
172 work for more complex things.
174 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
176 * x86.brg (freg): use fprem instead of fprem1
178 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
180 * jit.c (ves_array_element_address): added check for out of range index

191 2002-09-27 Martin Baulig <martin@gnome.org>
193 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
195 2002-09-27 Dick Porter <dick@ximian.com>
197 * mono.c: Tell glib what the program name is, by passing it the
198 name of the managed file we're executing
200 2002-09-26 Martin Baulig <martin@gnome.org>
202 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
203 trampoline into the vtable, also use it for non-virtual methods,
204 remove the breakpoint when done.
206 2002-09-26 Martin Baulig <martin@gnome.org>
208 * debug.c (debug_load_method_lines): Block SIGCHLD while running
211 2002-09-26 Martin Baulig <martin@gnome.org>
213 * debug.c: Reworked the whole debugging stuff. We have now one
214 single `mono_debug_handle' which keeps a hashtable of
215 `AssemblyDebugInfo's (which may have different debugging formats).
216 The AssemblyDebugInfo is now created when the assembly is loaded,
217 but never when adding a class/type.
219 * mono.c: Initialize debugging stuff after corlib and the assembly
222 2002-09-25 Martin Baulig <martin@gnome.org>
224 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
225 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
227 (DebugMethodInfo): Removed `line_numbers'.
229 * debug.c: Reworked the line number generation; we're now using
230 the MonoDebugLineNumberEntry try for all debugging formats. This
231 type also includes the line number and IL offset, this allows the
232 JIT to produce better line number info: we only emit line number
233 information for source lines which actually have code.
235 2002-09-25 Martin Baulig <martin@gnome.org>
237 * debug.h: Removed external declaration of all functions which
238 should only be called from the Mono Debugger and also made them
239 static. Since the debugger gets their address from the
240 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
243 2002-09-25 Martin Baulig <martin@gnome.org>
245 Improved breakpoint support, we can now dynamically insert and
246 remove breakpoints at runtime and when called from withing the
247 Mono Debugger, we're using a special breakpoint trampoline.
249 * debug.h (mono_method_has_breakpoint): New method to check
250 whether to insert a breakpoint for a method.
251 (mono_insert_breakpoint): New method to insert a breakpoint.
252 (mono_insert_breakpoint_full): New method to insert a breakpoint,
253 takes a MonoMethodDesc.
254 (mono_remove_breakpoint): New method to remove a breakpoint.
256 * debug.c (mono_debugger_insert_breakpoint): New function for the
257 debugger. Should only be called from the debugger.
258 (mono_debugger_remove_breakpoint): Likewise.
260 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
262 * trampoline.c (get_breakpoint_trampoline): New static function to
263 create a special breakpoint trampoline for the debugger.
264 (x86_magic_trampoline): If we're running inside the Mono Debugger
265 and a breakpoint was requested for the method, generate a special
266 breakpoint trampoline.
268 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
269 to insert a breakpoint.
270 (mono_debug_last_breakpoint_address): Removed.
271 (match_debug_method): Removed, use mono_method_has_breakpoint().
273 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
275 * jit.c: reorder mono_runtime_cleanup () call since it needs the
276 engine still fully working.
278 2002-09-24 Martin Baulig <martin@gnome.org>
280 * debug.c (mono_debug_open): When we're invoked from inside the
281 Mono Debugger, set mono_debugger_class_init_func (exported in
282 metadata/class.c) to mono_add_type().
283 (mono_add_type): Call mono_debug_symfile_add_type().
285 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
287 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
288 Run finalize on domain cleanup.
289 * mono.c: call setlocale ().
290 * trampoline.c: clearer error message for invalid trampoline.
292 2002-09-21 Martin Baulig <martin@gnome.org>
294 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
295 instead of writing a byte blob.
296 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
297 (mono_debug_add_method): Incrementally add the new method to the symbol
300 * exception.c (arch_handle_exception): If we have debugging support,
301 call mono_debugger_update_symbol_file_table () as well.
303 2002-09-20 Martin Baulig <martin@gnome.org>
305 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
306 the size of the variable.
308 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
310 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
311 iterations if we visit blocks in reverse order.
313 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
315 * jit.c (mono_analyze_stack): cleaup of the array code
317 * exception.c: added patch from Julio Merno to fix bug #30048
319 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
321 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
323 * x86.brg (LDELEMA): use x86_lea
325 2002-09-06 Martin Baulig <martin@gnome.org>
327 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
328 If you were getting random crashes when using the JIT with debugging
329 turned on, this fixes it.
331 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
333 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
335 2002-09-05 Martin Baulig <martin@gnome.org>
337 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
338 which is read by the debugger.
340 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

343 to reduce exported symbols.
345 2002-09-03 Martin Baulig <martin@gnome.org>
347 * debug.c (free_method_info): Make this actually work.
349 2002-09-03 Martin Baulig <martin@gnome.org>
351 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
352 * debug-dwarf2-plus.c: Removed.
354 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
355 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
356 `mono_symfile' to `symfile'.
358 * debug.c (mono_debug_open): Replaced the assembly argument with a
359 file name argument; you can now call this before loading the assembly.
360 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
361 we now use MonoSymbolFileLineNumberEntry's and a separate address array
362 instead; splitted out all MonoSymbolFileLineNumberEntry code into
363 debug_generate_il_offsets() and debug_update_il_offsets().
364 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
365 created when reading the symbol file or from debug_load_method_lines().
366 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
368 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
369 looking up an address.

385 2002-08-27 Martin Baulig <martin@gnome.org>
387 * debug.c: The mono symbol file is installed together with the assembly
388 it belongs to and it's used on a per-image basis.
390 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
392 * mono.c: don't use the cil-coff header outside of the loader.
394 2002-08-27 Martin Baulig <martin@gnome.org>
396 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
397 to use global variables for this since they're stored in a core file.
398 (mono_debugger_symbol_file_table_generation): New global variable.
399 (mono_debugger_symbol_file_table): New global variable.
400 (mono_debugger_update_symbol_file_table): New global function to update
401 the symbol file table.

405 * trampoline.c (mono_generic_trampoline_code): New global variable.
406 (arch_create_jit_trampoline): Use the new global variable to store the
407 generic trampoline code instead of using a static one. This allows the
408 debugger to access this variable to check whether a method is a trampoline.
410 * debug.h (mono_generic_trampoline_code): Added external declaration.
412 2002-08-27 Martin Baulig <martin@gnome.org>
414 * debug.c (MonoDebugHandle): Moved the method hash into the
415 AssemblyDebugInfo struct since we need to use a separate hash for each
418 * debug.c: Added special undocumented command line argument to create a
419 symbol file for IL files on-the-fly. In this case, we also need to create
420 the IL files and parse them.
421 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
423 2002-08-26 Martin Baulig <martin@gnome.org>

434 * debug.c (mono_debug_write_symbols): Added support for the new
437 * mono.c (main): The `--debug' argument now knows about a new
438 debugging format `mono' which will be used to display source lines
441 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
442 which will be used when displaying backtraces. It reads a new

460 null (so that it contains the full trace even when we rethrow the
463 2002-08-19 Nick Drochak <ndrochak@gol.com>
465 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
466 the algebraic form we are using. This also eliminated a silly overflow
467 of the intermediate result that was causing troubles.
469 2002-08-16 Nick Drochak <ndrochak@gol.com>
471 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
474 2002-08-15 Nick Drochak <ndrochak@gol.com>
476 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
477 will not fit in 64 bits. Fixes bug #27375.

492 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
494 * exception.c (arch_handle_exception): simply return and let the
495 libpthread/kernel restore the context. This should work on recent
496 versions of linuxthreads.
498 * jit.c (mono_runtime_install_handlers): switch back to use
499 sigaction from libpthreads. As long as this does not make problems
500 we should use this instead of syscall.
502 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
504 * jit.c: removed the createdelegate icall
505 (mono_analyze_stack): special case Array::Address()

510 mono_get_lmf_addr relocatable.
511 (arch_jit_compile_cfg): do not waste memory
512 (arch_jit_compile_cfg): use a mempool to store native code. This
513 improves locality of code.

517 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
519 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
521 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
522 than one page, it's necessary to allocate memory incrementally,
523 in page-size steps, performing stack-touch every time.
524 Also added LOCALLOC(CONST_I4) implementation.
526 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
528 * jit.c (mono_get_runtime_method): code cleanup
530 * x86.brg: we do not need to save EAX/ECX/EDX in stmt:
532 2002-07-24 Dietmar Maurer <dietmar@ximian.com>
534 * jit.c (mono_analyze_stack): added CEE_TAIL (but it is ignored)

942 2002-05-21 Martin Baulig <martin@gnome.org>
944 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
945 file for all assemblies. Currently, the JIT doesn't put all methods
946 from a single assembly into a continuous region of memory. We were

1211 * x86.brg (stmt): removed stmt: STIND_I4 (addr, coni4) rule
1212 because it slows down performance.

1337 use arch_method_call_message_new() to access the stack.
1338 (arch_end_invoke): wait until we really finished processing
1339 (async_invoke_abort): notify all listeners, not only a
1342 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1418 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1419 numbers, we still need to generate the IL offsets here. Emit line numbers
1420 for `prologue_end_offset' (the first line of actual code) and
1421 `epilogue_begin_offset' (the line of the method's closing brace).
1422 Don't crash if cfg->bblocks [i].forest is NULL.
1423 (mono_debug_add_method): Don't crash if we don't have line numbers.
1424 Initialize the newly added fields.
1426 * debug-stabs.c: Record first and last line, emit filename info at the

1429 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1430 emit line number info for the first and last line.
1432 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1434 * invoke.c (arch_create_delegate_trampoline): impl.

1441 * debug.h, debug.c: constify char* argument.
1443 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1466 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1467 we don't have line number information. Use `minfo->method_info.this_offset'
1468 instead of hardcoding 8.
1470 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1471 line number information.

1496 2002-03-23 Martin Baulig <martin@gnome.org>
1498 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1499 to do it before the X86_CMP.
1500 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1501 (reg: CLT (lreg, lreg)): Likewise.
1502 (reg: CLT_UN (lreg, lreg)): Likewise.

1532 removed everything which is already in MonoDebugMethodInfo.
1534 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.
1535 (mono_debug_make_symbols): Don't open the file or call as, this is done in the

1573 * debug.c (mono_debug_get_type): Recursively call this for all function members
1575 (mono_debug_add_method): Don't mangle function names, this must be done by the
1576 debugger backend if the debugging format needs mangled names.
1578 * debug-dwarf2.c: Improved support for classes, added member functions.
1580 2002-03-16 Martin Baulig <martin@gnome.org>
1582 * debug.c (mono_debug_get_type): Recursively call this for all members and
1583 parent classes of a class type.
1585 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1586 since GDB doesn't like Java very much.
1588 2002-03-16 Martin Baulig <martin@gnome.org>
1590 * debug-dwarf2.c: Added support for enums.
1592 2002-03-15 Martin Baulig <martin@gnome.org>

1613 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1615 (mono_debug_open_file): Added MonoDebugFormat argument.
1616 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1617 this function from GDB. It's now safe to call this function multiple times;
1618 it'll always write a complete debugging file.
1620 * debug.c: Splitted this file into a general part which remains in this file
1621 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1622 All public functions now call a corresponding format specific function.
1624 * debug.c: The following changes are private to debug.c:
1625 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1626 (record_line_number, debug_generate_method_lines): New private functions.
1627 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1628 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1629 mono_debug_open_assembly_dwarf2).
1630 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1631 now safe to call this function multiple times.
1632 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1633 returns an unique index for this type. It's used to ensure that we only write
1634 each class once to the debugging file.
1635 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1636 data structure, but don't directly write to the debugging file. This is done
1637 later from mono_debug_write_assembly().
1639 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1640 debugging output. Call mono_debug_close() on cleanup if necessary.
1642 2002-03-14 Martin Baulig <martin@gnome.org>
1644 * debug-private.h: New private header file.
1646 * debug-stabs.c: Added the stabs type generation stuff which was
1647 previously in debug.c.
1649 * debug-dwarf.c: Started to implement type support. We're currently
1650 only writing this most basic types to the dwarf file, but this will
1653 2002-03-13 Martin Baulig <martin@gnome.org>
1655 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1656 debugging code. They're now in CVS, but not yet used anywhere.
1658 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1660 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1661 macros, included new delegate code from Daniel Stodden.
1664 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1666 * jit.c: verify that corlib and runtime are in sync.
1668 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1670 * emit-x86.c, jit.c: use the debug-helpers facilities to
1671 describe and match a method when debugging.
1673 2002-03-10 Martin Baulig <martin@gnome.org>
1675 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1676 output, put a nop instruction at the start of all functions so that
1677 the adresses won't change when using --debug.
1679 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1680 the bytecode area, stabs needs a line number in the .il file. Use the
1681 new info->moffsets to get the line number.
1682 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1683 `moffsets' is an array of `total_lines' fields (total number of lines
1684 in the .il file); for each line in the .il field, this array contains
1685 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1686 of a method and 0 otherwise.
1687 (debug_load_method_lines): Read the whole .il file and initialize the
1688 info->moffsets field.
1690 2002-03-09 Martin Baulig <martin@gnome.org>
1692 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1693 the unnecessary CDQ instruction.
1695 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1697 * jit.c (mono_analyze_stack): only load addresses of value types
1698 on the runtime stack.
1700 2002-03-07 Duncan Mak <duncan@ximian.com>
1702 * Makefile.am: A small patch fixing errors in vpath-based builds
1703 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1704 committed for Daniel Stodden <stodden@in.tum.de>.
1706 Thu Mar 7 17:22:52 CET 2002 Paolo Molaro <lupus@ximian.com>

2296 (MB_OPT_LEVEL): define optimisation level macro
2298 * testjit.c (tree_allocate_regs): added a way to prevent EDX usage
2299 for operations like idiv. it is also possible to assign specific registers.
2301 2001-09-20 Dietmar Maurer <dietmar@ximian.com>
2303 * x86.brg: added basic support for long
2305 * testjit.c (mono_compile_method): implemented POP
2307 2001-09-19 Miguel de Icaza <miguel@ximian.com>
2309 * testjit.c (usage): Added a couple of more usage options.
2311 2001-09-19 Dietmar Maurer <dietmar@ximian.com>
2313 * x86.brg: added more floating point grammar
2315 * testjit.c (mono_compile_method): make local offsets negative
2317 * x86.brg: added some floating point trees
2319 * testjit.c (mono_compile_method): arguments on the runtime
2320 stack are at least 4 bytes
2322 * x86.brg: partly implemented 8,16 bit integers
2324 * testjit.c (get_address): mark basic blocks
2326 2001-09-18 Dietmar Maurer <dietmar@ximian.com>
2328 * x86.brg: added some rules to optimize code
2330 * testjit.c (get_address): use a binary search to get the address
2331 (main): added an option to debug the jit (-d)
2333 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2335 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2337 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2339 * testjit.c (mono_compile_method): Provide better error reporting.
2341 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2343 * testjit.c (tree_get_address): impl. to fix address bug
2344 (tree_get_address): make sure that we can only jump to the first
2345 instruction of a tree.
2347 * x86.brg: emit real code for calls
2349 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2351 (mono_compile_method): reversed argument order
2353 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2355 * x86.brg (stmt): don't emit unnecessary register moves
2357 * testjit.c (tree_allocate_regs): free registers earlier
2359 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
2361 * x86.brg: branch addresses are now resolved
2363 * testjit.c (compute_branches): compute address of branches
2365 * x86.brg: emit real x86 instructions
2367 * testjit.c: call objdump to disassemble the output
2369 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2371 * x86.brg: use the right offsets to access local variables
2374 * emit-x86.c: only save/restore callee saved registers if they are
2377 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2379 (mono_compile_method): changed the tree for mothod calls
2386 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2388 * x86.brg: Use Unix assembly syntax.
2390 * emit-x86.c: support code, should be moved
2392 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2393 inefficient at appends.
2395 * Renamed `create_new_leave' to `create_new_leaf'
