1 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
3 * debug.c: Move must_send_finished var declaration out of #if win32 block (this fixes the build on win32)
5 2003-01-05 Martin Baulig <martin@ximian.com>
7 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
8 this is used when we're running inside the Mono Debugger
9 (mono_debugger_wait): Put the waiting code into a function of its own.
11 * mono.c (main): Call mono_debugger_jit_exec() instead of
12 mono_jit_exec() if we're running inside the Mono Debugger.
14 2003-01-05 Martin Baulig <martin@ximian.com>
16 * debug.h (MonoDebugFormat): Added
17 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
18 we're running inside the Mono Debugger prior to the args parsing.
20 2003-01-04 Martin Baulig <martin@ximian.com>
22 * debug.c (release_symbol_file_table): Only call this if we're
23 actually modifying the symbol tables.
24 (mono_debug_open): Always set the `mono_debugger_class_init_func'
25 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
27 2003-01-03 Martin Baulig <martin@ximian.com>
29 * debug.c: Disable the mono debugger stuff on Windows.
31 2003-01-03 Martin Baulig <martin@ximian.com>
33 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
34 function. This is called from the breakpoint trampoline to signal
35 the debugger and wait until it has reload the symbol tables.
37 * trampoline.c (get_breakpoint_trampoline): Call the new
38 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
39 trampoline just before the breakpoint.
41 2002-12-31 Martin Baulig <martin@ximian.com>
43 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
44 field to point to the MonoGlobalSymbolTable.
46 2002-12-30 Martin Baulig <martin@ximian.com>
48 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
49 This variable now specifies that the symbol tables have been
50 modified after the last notification has been send. The debugger
51 uses this flag to check whether it needs to reload the symbol
53 (debugger_compile_method): Just send a notification to the
54 debugger, but don't set the modified flag. It may or may not be
55 set when the debugger gets the notification - depending on whether
56 the JIT compilation added a new method to the symbol tables.
58 2002-12-30 Martin Baulig <martin@ximian.com>
60 * debug.c (debugger_compile_method): This is a wrapper around
61 mono_compile_method() which always sends a notification to the
64 2002-12-30 Martin Baulig <martin@ximian.com>
66 * debug.c: Reload the symbol file table before sending the
67 notification event to the debugger.
68 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
70 2002-12-31 Martin Baulig <martin@ximian.com>
72 * debug.c: Propertly lock everything and avoid race conditions.
73 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
75 2002-12-31 Duncan Mak <duncan@ximian.com>

78 declaring ret at the top of the function.
80 2002-12-30 Martin Baulig <martin@ximian.com>
82 * debug.c: When running under the mono debugger, create a special
83 debugger thread; always protect the symbol tables with a mutex.
85 2002-12-28 Martin Baulig <martin@ximian.com>
87 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
88 incremented each time one of the symbol tables is modified.
90 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
92 * jit.c: fix LDELEMA implementation here as well.
94 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
96 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.

106 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
108 * jit.c (mono_analyze_stack): call the utility function
109 mono_field_from_token to avoid code duplication.
111 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
113 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
115 * x86.brg (stmt): POP floating point stack correctly
117 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
119 * emit-x86.c (arch_emit_prologue): don't save caller saved
122 * exception.c (x86_unwind_native_frame): support exceptions inside
123 native code using gcc generated exception tables (-fexception).
125 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
127 * exception.c: include some code from Zoltan Varga, but modified
130 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
132 * exception.c: massive code cleanups. The code is still
133 architecture dependent, but it should be now possible to reuse the
134 complex parts for other architecture.
136 2002-11-15 Dick Porter <dick@ximian.com>
138 * jit.c: Pass the attach callback to mono_runtime_init().
140 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>

144 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
146 * x86.brg (reg): fix bug #2721
148 * jit.c (mono_runtime_install_handlers): impl.
150 2002-10-17 Martin Baulig <martin@gnome.org>
152 * debug.c (mono_debug_add_method): Make this actually work if we don't
153 have any lifetime information.
155 2002-10-15 Martin Baulig <martin@gnome.org>
157 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
159 * debug.c (generate_line_number): Small fix to make this actually
160 work for more complex things.
162 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
164 * x86.brg (freg): use fprem instead of fprem1
166 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
168 * jit.c (ves_array_element_address): added check for out of range index

179 2002-09-27 Martin Baulig <martin@gnome.org>
181 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
183 2002-09-27 Dick Porter <dick@ximian.com>
185 * mono.c: Tell glib what the program name is, by passing it the
186 name of the managed file we're executing
188 2002-09-26 Martin Baulig <martin@gnome.org>
190 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
191 trampoline into the vtable, also use it for non-virtual methods,
192 remove the breakpoint when done.
194 2002-09-26 Martin Baulig <martin@gnome.org>
196 * debug.c (debug_load_method_lines): Block SIGCHLD while running
199 2002-09-26 Martin Baulig <martin@gnome.org>
201 * debug.c: Reworked the whole debugging stuff. We have now one
202 single `mono_debug_handle' which keeps a hashtable of
203 `AssemblyDebugInfo's (which may have different debugging formats).
204 The AssemblyDebugInfo is now created when the assembly is loaded,
205 but never when adding a class/type.
207 * mono.c: Initialize debugging stuff after corlib and the assembly
210 2002-09-25 Martin Baulig <martin@gnome.org>
212 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
213 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
215 (DebugMethodInfo): Removed `line_numbers'.
217 * debug.c: Reworked the line number generation; we're now using
218 the MonoDebugLineNumberEntry try for all debugging formats. This
219 type also includes the line number and IL offset, this allows the
220 JIT to produce better line number info: we only emit line number
221 information for source lines which actually have code.
223 2002-09-25 Martin Baulig <martin@gnome.org>
225 * debug.h: Removed external declaration of all functions which
226 should only be called from the Mono Debugger and also made them
227 static. Since the debugger gets their address from the
228 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
231 2002-09-25 Martin Baulig <martin@gnome.org>
233 Improved breakpoint support, we can now dynamically insert and
234 remove breakpoints at runtime and when called from withing the
235 Mono Debugger, we're using a special breakpoint trampoline.
237 * debug.h (mono_method_has_breakpoint): New method to check
238 whether to insert a breakpoint for a method.
239 (mono_insert_breakpoint): New method to insert a breakpoint.
240 (mono_insert_breakpoint_full): New method to insert a breakpoint,
241 takes a MonoMethodDesc.
242 (mono_remove_breakpoint): New method to remove a breakpoint.
244 * debug.c (mono_debugger_insert_breakpoint): New function for the
245 debugger. Should only be called from the debugger.
246 (mono_debugger_remove_breakpoint): Likewise.
248 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
250 * trampoline.c (get_breakpoint_trampoline): New static function to
251 create a special breakpoint trampoline for the debugger.
252 (x86_magic_trampoline): If we're running inside the Mono Debugger
253 and a breakpoint was requested for the method, generate a special
254 breakpoint trampoline.
256 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
257 to insert a breakpoint.
258 (mono_debug_last_breakpoint_address): Removed.
259 (match_debug_method): Removed, use mono_method_has_breakpoint().
261 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
263 * jit.c: reorder mono_runtime_cleanup () call since it needs the
264 engine still fully working.
266 2002-09-24 Martin Baulig <martin@gnome.org>
268 * debug.c (mono_debug_open): When we're invoked from inside the
269 Mono Debugger, set mono_debugger_class_init_func (exported in
270 metadata/class.c) to mono_add_type().
271 (mono_add_type): Call mono_debug_symfile_add_type().
273 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
275 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
276 Run finalize on domain cleanup.
277 * mono.c: call setlocale ().
278 * trampoline.c: clearer error message for invalid trampoline.
280 2002-09-21 Martin Baulig <martin@gnome.org>
282 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
283 instead of writing a byte blob.
284 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
285 (mono_debug_add_method): Incrementally add the new method to the symbol
288 * exception.c (arch_handle_exception): If we have debugging support,
289 call mono_debugger_update_symbol_file_table () as well.
291 2002-09-20 Martin Baulig <martin@gnome.org>
293 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
294 the size of the variable.
296 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
298 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
299 iterations if we visit blocks in reverse order.
301 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
303 * jit.c (mono_analyze_stack): cleaup of the array code
305 * exception.c: added patch from Julio Merno to fix bug #30048
307 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
309 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
311 * x86.brg (LDELEMA): use x86_lea
313 2002-09-06 Martin Baulig <martin@gnome.org>
315 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
316 If you were getting random crashes when using the JIT with debugging
317 turned on, this fixes it.
319 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
321 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
323 2002-09-05 Martin Baulig <martin@gnome.org>
325 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
326 which is read by the debugger.
328 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

331 to reduce exported symbols.
333 2002-09-03 Martin Baulig <martin@gnome.org>
335 * debug.c (free_method_info): Make this actually work.
337 2002-09-03 Martin Baulig <martin@gnome.org>
339 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
340 * debug-dwarf2-plus.c: Removed.
342 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
343 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
344 `mono_symfile' to `symfile'.
346 * debug.c (mono_debug_open): Replaced the assembly argument with a
347 file name argument; you can now call this before loading the assembly.
348 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
349 we now use MonoSymbolFileLineNumberEntry's and a separate address array
350 instead; splitted out all MonoSymbolFileLineNumberEntry code into
351 debug_generate_il_offsets() and debug_update_il_offsets().
352 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
353 created when reading the symbol file or from debug_load_method_lines().
354 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
356 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
357 looking up an address.

373 2002-08-27 Martin Baulig <martin@gnome.org>
375 * debug.c: The mono symbol file is installed together with the assembly
376 it belongs to and it's used on a per-image basis.
378 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
380 * mono.c: don't use the cil-coff header outside of the loader.
382 2002-08-27 Martin Baulig <martin@gnome.org>
384 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
385 to use global variables for this since they're stored in a core file.

387 (mono_debugger_symbol_file_table): New global variable.
388 (mono_debugger_update_symbol_file_table): New global function to update

393 * trampoline.c (mono_generic_trampoline_code): New global variable.
394 (arch_create_jit_trampoline): Use the new global variable to store the
395 generic trampoline code instead of using a static one. This allows the
396 debugger to access this variable to check whether a method is a trampoline.
398 * debug.h (mono_generic_trampoline_code): Added external declaration.
400 2002-08-27 Martin Baulig <martin@gnome.org>
402 * debug.c (MonoDebugHandle): Moved the method hash into the
403 AssemblyDebugInfo struct since we need to use a separate hash for each
406 * debug.c: Added special undocumented command line argument to create a
407 symbol file for IL files on-the-fly. In this case, we also need to create
408 the IL files and parse them.
409 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
411 2002-08-26 Martin Baulig <martin@gnome.org>

426 debugging format `mono' which will be used to display source lines
429 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
430 which will be used when displaying backtraces. It reads a new

453 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
454 the algebraic form we are using. This also eliminated a silly overflow
455 of the intermediate result that was causing troubles.
457 2002-08-16 Nick Drochak <ndrochak@gol.com>
459 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
462 2002-08-15 Nick Drochak <ndrochak@gol.com>
464 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
465 will not fit in 64 bits. Fixes bug #27375.

480 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
482 * exception.c (arch_handle_exception): simply return and let the
483 libpthread/kernel restore the context. This should work on recent
484 versions of linuxthreads.
486 * jit.c (mono_runtime_install_handlers): switch back to use
487 sigaction from libpthreads. As long as this does not make problems
488 we should use this instead of syscall.
490 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
492 * jit.c: removed the createdelegate icall
493 (mono_analyze_stack): special case Array::Address()

498 mono_get_lmf_addr relocatable.
499 (arch_jit_compile_cfg): do not waste memory

505 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
507 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
509 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
510 than one page, it's necessary to allocate memory incrementally,
511 in page-size steps, performing stack-touch every time.
512 Also added LOCALLOC(CONST_I4) implementation.
514 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
516 * jit.c (mono_get_runtime_method): code cleanup
518 * x86.brg: we do not need to save EAX/ECX/EDX in stmt:

930 2002-05-21 Martin Baulig <martin@gnome.org>
932 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
933 file for all assemblies. Currently, the JIT doesn't put all methods
934 from a single assembly into a continuous region of memory. We were
935 previously creating valid DWARF 2 files for this, but unfortunately
936 GDB's symbol tables get messed up when it reads more than one such file.

1034 * exception.c (arch_handle_exception): EIP now points to the call
1035 instruction, not to the instruction after the call. This fixes the

1406 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1407 numbers, we still need to generate the IL offsets here. Emit line numbers
1408 for `prologue_end_offset' (the first line of actual code) and
1409 `epilogue_begin_offset' (the line of the method's closing brace).
1410 Don't crash if cfg->bblocks [i].forest is NULL.
1411 (mono_debug_add_method): Don't crash if we don't have line numbers.
1412 Initialize the newly added fields.
1414 * debug-stabs.c: Record first and last line, emit filename info at the

1417 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1418 emit line number info for the first and last line.
1420 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1454 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1455 we don't have line number information. Use `minfo->method_info.this_offset'
1456 instead of hardcoding 8.

1484 2002-03-23 Martin Baulig <martin@gnome.org>
1486 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1487 to do it before the X86_CMP.
1488 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1489 (reg: CLT (lreg, lreg)): Likewise.
1490 (reg: CLT_UN (lreg, lreg)): Likewise.

1520 removed everything which is already in MonoDebugMethodInfo.
1522 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1559 2002-03-17 Martin Baulig <martin@gnome.org>
1561 * debug.c (mono_debug_get_type): Recursively call this for all function members
1563 (mono_debug_add_method): Don't mangle function names, this must be done by the
1564 debugger backend if the debugging format needs mangled names.
1566 * debug-dwarf2.c: Improved support for classes, added member functions.
1568 2002-03-16 Martin Baulig <martin@gnome.org>
1570 * debug.c (mono_debug_get_type): Recursively call this for all members and
1571 parent classes of a class type.
1573 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1574 since GDB doesn't like Java very much.
1576 2002-03-16 Martin Baulig <martin@gnome.org>
1578 * debug-dwarf2.c: Added support for enums.
1580 2002-03-15 Martin Baulig <martin@gnome.org>

1601 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1603 (mono_debug_open_file): Added MonoDebugFormat argument.
1604 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1605 this function from GDB. It's now safe to call this function multiple times;
1606 it'll always write a complete debugging file.
1608 * debug.c: Splitted this file into a general part which remains in this file
1609 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1610 All public functions now call a corresponding format specific function.
1612 * debug.c: The following changes are private to debug.c:
1613 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1614 (record_line_number, debug_generate_method_lines): New private functions.
1615 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1616 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1617 mono_debug_open_assembly_dwarf2).
1618 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1619 now safe to call this function multiple times.
1620 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1621 returns an unique index for this type. It's used to ensure that we only write
1622 each class once to the debugging file.
1623 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1624 data structure, but don't directly write to the debugging file. This is done
1625 later from mono_debug_write_assembly().
1627 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1628 debugging output. Call mono_debug_close() on cleanup if necessary.
1630 2002-03-14 Martin Baulig <martin@gnome.org>
1632 * debug-private.h: New private header file.
1634 * debug-stabs.c: Added the stabs type generation stuff which was
1635 previously in debug.c.
1637 * debug-dwarf.c: Started to implement type support. We're currently
1638 only writing this most basic types to the dwarf file, but this will
1641 2002-03-13 Martin Baulig <martin@gnome.org>
1643 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1644 debugging code. They're now in CVS, but not yet used anywhere.
1646 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1648 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1649 macros, included new delegate code from Daniel Stodden.
1652 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1654 * jit.c: verify that corlib and runtime are in sync.
1656 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1658 * emit-x86.c, jit.c: use the debug-helpers facilities to
1659 describe and match a method when debugging.
1661 2002-03-10 Martin Baulig <martin@gnome.org>
1663 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1664 output, put a nop instruction at the start of all functions so that
1665 the adresses won't change when using --debug.
1667 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1668 the bytecode area, stabs needs a line number in the .il file. Use the
1669 new info->moffsets to get the line number.
1670 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1671 `moffsets' is an array of `total_lines' fields (total number of lines
1672 in the .il file); for each line in the .il field, this array contains
1673 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1674 of a method and 0 otherwise.
1675 (debug_load_method_lines): Read the whole .il file and initialize the
1676 info->moffsets field.
1678 2002-03-09 Martin Baulig <martin@gnome.org>
1680 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1681 the unnecessary CDQ instruction.
1683 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1685 * jit.c (mono_analyze_stack): only load addresses of value types
1686 on the runtime stack.
1688 2002-03-07 Duncan Mak <duncan@ximian.com>
1690 * Makefile.am: A small patch fixing errors in vpath-based builds
1691 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1692 committed for Daniel Stodden <stodden@in.tum.de>.
1694 Thu Mar 7 17:22:52 CET 2002 Paolo Molaro <lupus@ximian.com>

2299 2001-09-19 Dietmar Maurer <dietmar@ximian.com>
2301 * x86.brg: added more floating point grammar
2303 * testjit.c (mono_compile_method): make local offsets negative
2305 * x86.brg: added some floating point trees
2307 * testjit.c (mono_compile_method): arguments on the runtime
2308 stack are at least 4 bytes
2310 * x86.brg: partly implemented 8,16 bit integers
2312 * testjit.c (get_address): mark basic blocks
2314 2001-09-18 Dietmar Maurer <dietmar@ximian.com>
2316 * x86.brg: added some rules to optimize code
2318 * testjit.c (get_address): use a binary search to get the address
2319 (main): added an option to debug the jit (-d)
2321 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2323 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2325 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2327 * testjit.c (mono_compile_method): Provide better error reporting.
2329 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2331 * testjit.c (tree_get_address): impl. to fix address bug
2332 (tree_get_address): make sure that we can only jump to the first
2333 instruction of a tree.
2335 * x86.brg: emit real code for calls
2337 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2339 (mono_compile_method): reversed argument order
2341 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2343 * x86.brg (stmt): don't emit unnecessary register moves
2345 * testjit.c (tree_allocate_regs): free registers earlier
2347 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
2349 * x86.brg: branch addresses are now resolved
2351 * testjit.c (compute_branches): compute address of branches
2353 * x86.brg: emit real x86 instructions
2355 * testjit.c: call objdump to disassemble the output
2357 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2359 * x86.brg: use the right offsets to access local variables
2362 * emit-x86.c: only save/restore callee saved registers if they are
2365 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2367 (mono_compile_method): changed the tree for mothod calls
2374 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2376 * x86.brg: Use Unix assembly syntax.
2378 * emit-x86.c: support code, should be moved
2380 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2381 inefficient at appends.
2383 * Renamed `create_new_leave' to `create_new_leaf'
