10 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
12 * jit.c: handle wrapper_data in NEWOBJ/CALL.
14 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
16 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
18 2003-01-06 Martin Baulig <martin@ximian.com>
20 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
22 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
23 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
25 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
27 * debug.c: Move must_send_finished var declaration out of #if win32
28 block (this fixes the build on win32)
30 2003-01-05 Martin Baulig <martin@ximian.com>
32 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
33 this is used when we're running inside the Mono Debugger
34 (mono_debugger_wait): Put the waiting code into a function of its own.
36 * mono.c (main): Call mono_debugger_jit_exec() instead of
37 mono_jit_exec() if we're running inside the Mono Debugger.
39 2003-01-05 Martin Baulig <martin@ximian.com>
41 * debug.h (MonoDebugFormat): Added
42 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
43 we're running inside the Mono Debugger prior to the args parsing.
45 2003-01-04 Martin Baulig <martin@ximian.com>
47 * debug.c (release_symbol_file_table): Only call this if we're
48 actually modifying the symbol tables.
49 (mono_debug_open): Always set the `mono_debugger_class_init_func'
50 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
52 2003-01-03 Martin Baulig <martin@ximian.com>
54 * debug.c: Disable the mono debugger stuff on Windows.
56 2003-01-03 Martin Baulig <martin@ximian.com>
58 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
59 function. This is called from the breakpoint trampoline to signal
60 the debugger and wait until it has reload the symbol tables.
62 * trampoline.c (get_breakpoint_trampoline): Call the new
63 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
64 trampoline just before the breakpoint.
66 2002-12-31 Martin Baulig <martin@ximian.com>
68 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
69 field to point to the MonoGlobalSymbolTable.
71 2002-12-30 Martin Baulig <martin@ximian.com>
73 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
74 This variable now specifies that the symbol tables have been
75 modified after the last notification has been send. The debugger
76 uses this flag to check whether it needs to reload the symbol
78 (debugger_compile_method): Just send a notification to the
79 debugger, but don't set the modified flag. It may or may not be
80 set when the debugger gets the notification - depending on whether
81 the JIT compilation added a new method to the symbol tables.
83 2002-12-30 Martin Baulig <martin@ximian.com>
85 * debug.c (debugger_compile_method): This is a wrapper around
86 mono_compile_method() which always sends a notification to the
89 2002-12-30 Martin Baulig <martin@ximian.com>
91 * debug.c: Reload the symbol file table before sending the
92 notification event to the debugger.
93 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
95 2002-12-31 Martin Baulig <martin@ximian.com>
97 * debug.c: Propertly lock everything and avoid race conditions.
98 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.

103 declaring ret at the top of the function.
105 2002-12-30 Martin Baulig <martin@ximian.com>
107 * debug.c: When running under the mono debugger, create a special
108 debugger thread; always protect the symbol tables with a mutex.
110 2002-12-28 Martin Baulig <martin@ximian.com>
112 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
113 incremented each time one of the symbol tables is modified.
115 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
117 * jit.c: fix LDELEMA implementation here as well.
119 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>

133 * jit.c (mono_analyze_stack): call the utility function
134 mono_field_from_token to avoid code duplication.
136 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
138 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
140 * x86.brg (stmt): POP floating point stack correctly
142 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
144 * emit-x86.c (arch_emit_prologue): don't save caller saved
147 * exception.c (x86_unwind_native_frame): support exceptions inside
148 native code using gcc generated exception tables (-fexception).
150 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
152 * exception.c: include some code from Zoltan Varga, but modified
155 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
157 * exception.c: massive code cleanups. The code is still
158 architecture dependent, but it should be now possible to reuse the
159 complex parts for other architecture.
161 2002-11-15 Dick Porter <dick@ximian.com>
163 * jit.c: Pass the attach callback to mono_runtime_init().
165 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
167 * jit.c: display the domain name in trace output.
169 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
171 * x86.brg (reg): fix bug #2721
173 * jit.c (mono_runtime_install_handlers): impl.
175 2002-10-17 Martin Baulig <martin@gnome.org>

178 have any lifetime information.
180 2002-10-15 Martin Baulig <martin@gnome.org>
182 * jit.cs (PUSH_TREE): Always set t->cli_addr here.

204 2002-09-27 Martin Baulig <martin@gnome.org>
206 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
208 2002-09-27 Dick Porter <dick@ximian.com>
210 * mono.c: Tell glib what the program name is, by passing it the
211 name of the managed file we're executing
213 2002-09-26 Martin Baulig <martin@gnome.org>
215 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
216 trampoline into the vtable, also use it for non-virtual methods,
217 remove the breakpoint when done.
219 2002-09-26 Martin Baulig <martin@gnome.org>
221 * debug.c (debug_load_method_lines): Block SIGCHLD while running
224 2002-09-26 Martin Baulig <martin@gnome.org>
226 * debug.c: Reworked the whole debugging stuff. We have now one
227 single `mono_debug_handle' which keeps a hashtable of
228 `AssemblyDebugInfo's (which may have different debugging formats).
229 The AssemblyDebugInfo is now created when the assembly is loaded,
230 but never when adding a class/type.
232 * mono.c: Initialize debugging stuff after corlib and the assembly
235 2002-09-25 Martin Baulig <martin@gnome.org>
237 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
238 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
240 (DebugMethodInfo): Removed `line_numbers'.
242 * debug.c: Reworked the line number generation; we're now using
243 the MonoDebugLineNumberEntry try for all debugging formats. This
244 type also includes the line number and IL offset, this allows the
245 JIT to produce better line number info: we only emit line number
246 information for source lines which actually have code.
248 2002-09-25 Martin Baulig <martin@gnome.org>
250 * debug.h: Removed external declaration of all functions which
251 should only be called from the Mono Debugger and also made them
252 static. Since the debugger gets their address from the
253 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
256 2002-09-25 Martin Baulig <martin@gnome.org>
258 Improved breakpoint support, we can now dynamically insert and
259 remove breakpoints at runtime and when called from withing the
260 Mono Debugger, we're using a special breakpoint trampoline.
262 * debug.h (mono_method_has_breakpoint): New method to check
263 whether to insert a breakpoint for a method.
264 (mono_insert_breakpoint): New method to insert a breakpoint.
265 (mono_insert_breakpoint_full): New method to insert a breakpoint,
266 takes a MonoMethodDesc.
267 (mono_remove_breakpoint): New method to remove a breakpoint.
269 * debug.c (mono_debugger_insert_breakpoint): New function for the
270 debugger. Should only be called from the debugger.
271 (mono_debugger_remove_breakpoint): Likewise.
273 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
275 * trampoline.c (get_breakpoint_trampoline): New static function to
276 create a special breakpoint trampoline for the debugger.
277 (x86_magic_trampoline): If we're running inside the Mono Debugger
278 and a breakpoint was requested for the method, generate a special
279 breakpoint trampoline.
281 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
282 to insert a breakpoint.
283 (mono_debug_last_breakpoint_address): Removed.
284 (match_debug_method): Removed, use mono_method_has_breakpoint().
286 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
288 * jit.c: reorder mono_runtime_cleanup () call since it needs the
289 engine still fully working.
291 2002-09-24 Martin Baulig <martin@gnome.org>
293 * debug.c (mono_debug_open): When we're invoked from inside the
294 Mono Debugger, set mono_debugger_class_init_func (exported in
295 metadata/class.c) to mono_add_type().
296 (mono_add_type): Call mono_debug_symfile_add_type().
298 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
300 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
301 Run finalize on domain cleanup.
302 * mono.c: call setlocale ().
303 * trampoline.c: clearer error message for invalid trampoline.
305 2002-09-21 Martin Baulig <martin@gnome.org>
307 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
308 instead of writing a byte blob.
309 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
310 (mono_debug_add_method): Incrementally add the new method to the symbol
313 * exception.c (arch_handle_exception): If we have debugging support,
314 call mono_debugger_update_symbol_file_table () as well.
316 2002-09-20 Martin Baulig <martin@gnome.org>
318 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
319 the size of the variable.
321 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
323 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
324 iterations if we visit blocks in reverse order.
326 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
328 * jit.c (mono_analyze_stack): cleaup of the array code
330 * exception.c: added patch from Julio Merno to fix bug #30048

334 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
336 * x86.brg (LDELEMA): use x86_lea
338 2002-09-06 Martin Baulig <martin@gnome.org>
340 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
341 If you were getting random crashes when using the JIT with debugging
342 turned on, this fixes it.
344 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
346 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
348 2002-09-05 Martin Baulig <martin@gnome.org>
350 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
351 which is read by the debugger.
353 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

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

398 2002-08-27 Martin Baulig <martin@gnome.org>
400 * debug.c: The mono symbol file is installed together with the assembly
401 it belongs to and it's used on a per-image basis.
403 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
405 * mono.c: don't use the cil-coff header outside of the loader.
407 2002-08-27 Martin Baulig <martin@gnome.org>
409 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
410 to use global variables for this since they're stored in a core file.
411 (mono_debugger_symbol_file_table_generation): New global variable.
412 (mono_debugger_symbol_file_table): New global variable.
413 (mono_debugger_update_symbol_file_table): New global function to update
414 the symbol file table.

418 * trampoline.c (mono_generic_trampoline_code): New global variable.
419 (arch_create_jit_trampoline): Use the new global variable to store the
420 generic trampoline code instead of using a static one. This allows the
421 debugger to access this variable to check whether a method is a trampoline.
423 * debug.h (mono_generic_trampoline_code): Added external declaration.
425 2002-08-27 Martin Baulig <martin@gnome.org>
427 * debug.c (MonoDebugHandle): Moved the method hash into the
428 AssemblyDebugInfo struct since we need to use a separate hash for each
431 * debug.c: Added special undocumented command line argument to create a
432 symbol file for IL files on-the-fly. In this case, we also need to create
433 the IL files and parse them.

445 2002-08-24 Martin Baulig <martin@gnome.org>
447 * debug.c (mono_debug_write_symbols): Added support for the new
450 * mono.c (main): The `--debug' argument now knows about a new
451 debugging format `mono' which will be used to display source lines
454 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
455 which will be used when displaying backtraces. It reads a new

476 2002-08-19 Nick Drochak <ndrochak@gol.com>
478 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
479 the algebraic form we are using. This also eliminated a silly overflow
480 of the intermediate result that was causing troubles.
482 2002-08-16 Nick Drochak <ndrochak@gol.com>
484 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
487 2002-08-15 Nick Drochak <ndrochak@gol.com>
489 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
490 will not fit in 64 bits. Fixes bug #27375.
492 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>

505 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
507 * exception.c (arch_handle_exception): simply return and let the
508 libpthread/kernel restore the context. This should work on recent
509 versions of linuxthreads.
511 * jit.c (mono_runtime_install_handlers): switch back to use
512 sigaction from libpthreads. As long as this does not make problems
513 we should use this instead of syscall.
515 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
517 * jit.c: removed the createdelegate icall
518 (mono_analyze_stack): special case Array::Address()

523 mono_get_lmf_addr relocatable.
524 (arch_jit_compile_cfg): do not waste memory
525 (arch_jit_compile_cfg): use a mempool to store native code. This
526 improves locality of code.
528 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
530 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
532 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
534 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
535 than one page, it's necessary to allocate memory incrementally,
536 in page-size steps, performing stack-touch every time.
537 Also added LOCALLOC(CONST_I4) implementation.
539 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
541 * jit.c (mono_get_runtime_method): code cleanup
543 * x86.brg: we do not need to save EAX/ECX/EDX in stmt:
545 2002-07-24 Dietmar Maurer <dietmar@ximian.com>
547 * jit.c (mono_analyze_stack): added CEE_TAIL (but it is ignored)

957 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
958 file for all assemblies. Currently, the JIT doesn't put all methods
959 from a single assembly into a continuous region of memory. We were

1345 we need to pass the MonoMethod pointer as first argument.
1347 * delegate.c (mono_async_invoke): notify all listeners, not only a
1349 (arch_end_invoke): we now pass a MonoMethod as first parameter and
1350 use arch_method_call_message_new() to access the stack.
1351 (arch_end_invoke): wait until we really finished processing
1352 (async_invoke_abort): notify all listeners, not only a
1355 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1412 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1413 (AssemblyDebugInfo): Added `format'.
1415 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1416 this allows us choose the format on a per-assembly basis.
1417 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
1418 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file

1431 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1432 numbers, we still need to generate the IL offsets here. Emit line numbers
1433 for `prologue_end_offset' (the first line of actual code) and
1434 `epilogue_begin_offset' (the line of the method's closing brace).
1435 Don't crash if cfg->bblocks [i].forest is NULL.
1436 (mono_debug_add_method): Don't crash if we don't have line numbers.
1437 Initialize the newly added fields.
1439 * debug-stabs.c: Record first and last line, emit filename info at the
1440 beginning of the stab file, gdb ignores the types otherwise.
1442 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1443 emit line number info for the first and last line.
1445 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1447 * invoke.c (arch_create_delegate_trampoline): impl.

1454 * debug.h, debug.c: constify char* argument.
1456 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1479 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1480 we don't have line number information. Use `minfo->method_info.this_offset'
1481 instead of hardcoding 8.
1483 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1484 line number information.

1507 the `minfo->method_info.param_offsets' array.
1509 2002-03-23 Martin Baulig <martin@gnome.org>
1511 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1512 to do it before the X86_CMP.
1513 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1514 (reg: CLT (lreg, lreg)): Likewise.
1515 (reg: CLT_UN (lreg, lreg)): Likewise.

1593 2002-03-16 Martin Baulig <martin@gnome.org>
1595 * debug.c (mono_debug_get_type): Recursively call this for all members and
1596 parent classes of a class type.
1598 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1599 since GDB doesn't like Java very much.
1601 2002-03-16 Martin Baulig <martin@gnome.org>
1603 * debug-dwarf2.c: Added support for enums.
1605 2002-03-15 Martin Baulig <martin@gnome.org>

1626 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1628 (mono_debug_open_file): Added MonoDebugFormat argument.
1629 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1630 this function from GDB. It's now safe to call this function multiple times;
1631 it'll always write a complete debugging file.
1633 * debug.c: Splitted this file into a general part which remains in this file
1634 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1635 All public functions now call a corresponding format specific function.
1637 * debug.c: The following changes are private to debug.c:
1638 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1639 (record_line_number, debug_generate_method_lines): New private functions.
1640 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1641 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1642 mono_debug_open_assembly_dwarf2).
1643 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1644 now safe to call this function multiple times.
1645 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1646 returns an unique index for this type. It's used to ensure that we only write
1647 each class once to the debugging file.
1648 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1649 data structure, but don't directly write to the debugging file. This is done
1650 later from mono_debug_write_assembly().
1652 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1653 debugging output. Call mono_debug_close() on cleanup if necessary.
1655 2002-03-14 Martin Baulig <martin@gnome.org>
1657 * debug-private.h: New private header file.
1659 * debug-stabs.c: Added the stabs type generation stuff which was
1660 previously in debug.c.
1662 * debug-dwarf.c: Started to implement type support. We're currently
1663 only writing this most basic types to the dwarf file, but this will
1666 2002-03-13 Martin Baulig <martin@gnome.org>
1668 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1669 debugging code. They're now in CVS, but not yet used anywhere.
1671 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1673 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1674 macros, included new delegate code from Daniel Stodden.
1677 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1679 * jit.c: verify that corlib and runtime are in sync.
1681 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1683 * emit-x86.c, jit.c: use the debug-helpers facilities to
1684 describe and match a method when debugging.
1686 2002-03-10 Martin Baulig <martin@gnome.org>
1688 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1689 output, put a nop instruction at the start of all functions so that
1690 the adresses won't change when using --debug.
1692 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1693 the bytecode area, stabs needs a line number in the .il file. Use the
1694 new info->moffsets to get the line number.
1695 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1696 `moffsets' is an array of `total_lines' fields (total number of lines
1697 in the .il file); for each line in the .il field, this array contains
1698 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1699 of a method and 0 otherwise.
1700 (debug_load_method_lines): Read the whole .il file and initialize the
1701 info->moffsets field.
1703 2002-03-09 Martin Baulig <martin@gnome.org>
1705 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1706 the unnecessary CDQ instruction.
1708 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1710 * jit.c (mono_analyze_stack): only load addresses of value types
1711 on the runtime stack.
1713 2002-03-07 Duncan Mak <duncan@ximian.com>
1715 * Makefile.am: A small patch fixing errors in vpath-based builds

2326 * x86.brg: added more floating point grammar
2328 * testjit.c (mono_compile_method): make local offsets negative
2330 * x86.brg: added some floating point trees

2333 stack are at least 4 bytes
2335 * x86.brg: partly implemented 8,16 bit integers
2337 * testjit.c (get_address): mark basic blocks
2339 2001-09-18 Dietmar Maurer <dietmar@ximian.com>

2346 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2348 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2350 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2352 * testjit.c (mono_compile_method): Provide better error reporting.
2354 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2356 * testjit.c (tree_get_address): impl. to fix address bug
2357 (tree_get_address): make sure that we can only jump to the first
2358 instruction of a tree.
2360 * x86.brg: emit real code for calls
2362 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2364 (mono_compile_method): reversed argument order
2366 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2368 * x86.brg (stmt): don't emit unnecessary register moves

2374 * x86.brg: branch addresses are now resolved
2376 * testjit.c (compute_branches): compute address of branches
2378 * x86.brg: emit real x86 instructions
2380 * testjit.c: call objdump to disassemble the output
2382 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2384 * x86.brg: use the right offsets to access local variables
2387 * emit-x86.c: only save/restore callee saved registers if they are
2390 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2392 (mono_compile_method): changed the tree for mothod calls
2399 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2401 * x86.brg: Use Unix assembly syntax.
2403 * emit-x86.c: support code, should be moved
2405 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2406 inefficient at appends.
2408 * Renamed `create_new_leave' to `create_new_leaf'
