1 2003-01-05 Martin Baulig <martin@ximian.com>
3 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
4 this is used when we're running inside the Mono Debugger
5 (mono_debugger_wait): Put the waiting code into a function of its own.
7 * mono.c (main): Call mono_debugger_jit_exec() instead of
8 mono_jit_exec() if we're running inside the Mono Debugger.
10 2003-01-05 Martin Baulig <martin@ximian.com>
12 * debug.h (MonoDebugFormat): Added
13 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
14 we're running inside the Mono Debugger prior to the args parsing.
16 2003-01-04 Martin Baulig <martin@ximian.com>
18 * debug.c (release_symbol_file_table): Only call this if we're
19 actually modifying the symbol tables.
20 (mono_debug_open): Always set the `mono_debugger_class_init_func'
21 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
23 2003-01-03 Martin Baulig <martin@ximian.com>
25 * debug.c: Disable the mono debugger stuff on Windows.
27 2003-01-03 Martin Baulig <martin@ximian.com>
29 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
30 function. This is called from the breakpoint trampoline to signal
31 the debugger and wait until it has reload the symbol tables.
33 * trampoline.c (get_breakpoint_trampoline): Call the new
34 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
35 trampoline just before the breakpoint.
37 2002-12-31 Martin Baulig <martin@ximian.com>
39 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
40 field to point to the MonoGlobalSymbolTable.
42 2002-12-30 Martin Baulig <martin@ximian.com>
44 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
45 This variable now specifies that the symbol tables have been
46 modified after the last notification has been send. The debugger
47 uses this flag to check whether it needs to reload the symbol
49 (debugger_compile_method): Just send a notification to the
50 debugger, but don't set the modified flag. It may or may not be
51 set when the debugger gets the notification - depending on whether
52 the JIT compilation added a new method to the symbol tables.
54 2002-12-30 Martin Baulig <martin@ximian.com>
56 * debug.c (debugger_compile_method): This is a wrapper around
57 mono_compile_method() which always sends a notification to the
60 2002-12-30 Martin Baulig <martin@ximian.com>
62 * debug.c: Reload the symbol file table before sending the
63 notification event to the debugger.
64 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
66 2002-12-31 Martin Baulig <martin@ximian.com>

74 declaring ret at the top of the function.
76 2002-12-30 Martin Baulig <martin@ximian.com>
78 * debug.c: When running under the mono debugger, create a special
79 debugger thread; always protect the symbol tables with a mutex.
81 2002-12-28 Martin Baulig <martin@ximian.com>
83 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
84 incremented each time one of the symbol tables is modified.
86 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
88 * jit.c: fix LDELEMA implementation here as well.
90 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>

109 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
111 * x86.brg (stmt): POP floating point stack correctly
113 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
115 * emit-x86.c (arch_emit_prologue): don't save caller saved
118 * exception.c (x86_unwind_native_frame): support exceptions inside
119 native code using gcc generated exception tables (-fexception).
121 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
123 * exception.c: include some code from Zoltan Varga, but modified
126 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
128 * exception.c: massive code cleanups. The code is still
129 architecture dependent, but it should be now possible to reuse the
130 complex parts for other architecture.
132 2002-11-15 Dick Porter <dick@ximian.com>
134 * jit.c: Pass the attach callback to mono_runtime_init().

175 2002-09-27 Martin Baulig <martin@gnome.org>
177 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
179 2002-09-27 Dick Porter <dick@ximian.com>
181 * mono.c: Tell glib what the program name is, by passing it the
182 name of the managed file we're executing
184 2002-09-26 Martin Baulig <martin@gnome.org>
186 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
187 trampoline into the vtable, also use it for non-virtual methods,
188 remove the breakpoint when done.
190 2002-09-26 Martin Baulig <martin@gnome.org>
192 * debug.c (debug_load_method_lines): Block SIGCHLD while running
195 2002-09-26 Martin Baulig <martin@gnome.org>
197 * debug.c: Reworked the whole debugging stuff. We have now one
198 single `mono_debug_handle' which keeps a hashtable of
199 `AssemblyDebugInfo's (which may have different debugging formats).
200 The AssemblyDebugInfo is now created when the assembly is loaded,
201 but never when adding a class/type.
203 * mono.c: Initialize debugging stuff after corlib and the assembly
206 2002-09-25 Martin Baulig <martin@gnome.org>
208 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
209 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
211 (DebugMethodInfo): Removed `line_numbers'.
213 * debug.c: Reworked the line number generation; we're now using
214 the MonoDebugLineNumberEntry try for all debugging formats. This
215 type also includes the line number and IL offset, this allows the
216 JIT to produce better line number info: we only emit line number
217 information for source lines which actually have code.
219 2002-09-25 Martin Baulig <martin@gnome.org>
221 * debug.h: Removed external declaration of all functions which
222 should only be called from the Mono Debugger and also made them
223 static. Since the debugger gets their address from the
224 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
227 2002-09-25 Martin Baulig <martin@gnome.org>
229 Improved breakpoint support, we can now dynamically insert and
230 remove breakpoints at runtime and when called from withing the
231 Mono Debugger, we're using a special breakpoint trampoline.
233 * debug.h (mono_method_has_breakpoint): New method to check
234 whether to insert a breakpoint for a method.
235 (mono_insert_breakpoint): New method to insert a breakpoint.
236 (mono_insert_breakpoint_full): New method to insert a breakpoint,
237 takes a MonoMethodDesc.
238 (mono_remove_breakpoint): New method to remove a breakpoint.
240 * debug.c (mono_debugger_insert_breakpoint): New function for the
241 debugger. Should only be called from the debugger.
242 (mono_debugger_remove_breakpoint): Likewise.
244 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
246 * trampoline.c (get_breakpoint_trampoline): New static function to
247 create a special breakpoint trampoline for the debugger.
248 (x86_magic_trampoline): If we're running inside the Mono Debugger
249 and a breakpoint was requested for the method, generate a special
250 breakpoint trampoline.
252 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
253 to insert a breakpoint.
254 (mono_debug_last_breakpoint_address): Removed.
255 (match_debug_method): Removed, use mono_method_has_breakpoint().
257 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
259 * jit.c: reorder mono_runtime_cleanup () call since it needs the
260 engine still fully working.
262 2002-09-24 Martin Baulig <martin@gnome.org>
264 * debug.c (mono_debug_open): When we're invoked from inside the
265 Mono Debugger, set mono_debugger_class_init_func (exported in
266 metadata/class.c) to mono_add_type().
267 (mono_add_type): Call mono_debug_symfile_add_type().
269 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
271 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
272 Run finalize on domain cleanup.
273 * mono.c: call setlocale ().
274 * trampoline.c: clearer error message for invalid trampoline.
276 2002-09-21 Martin Baulig <martin@gnome.org>
278 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
279 instead of writing a byte blob.
280 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
281 (mono_debug_add_method): Incrementally add the new method to the symbol
284 * exception.c (arch_handle_exception): If we have debugging support,
285 call mono_debugger_update_symbol_file_table () as well.
287 2002-09-20 Martin Baulig <martin@gnome.org>
289 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
290 the size of the variable.
292 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
294 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
295 iterations if we visit blocks in reverse order.
297 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
299 * jit.c (mono_analyze_stack): cleaup of the array code
301 * exception.c: added patch from Julio Merno to fix bug #30048

305 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
307 * x86.brg (LDELEMA): use x86_lea
309 2002-09-06 Martin Baulig <martin@gnome.org>
311 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
312 If you were getting random crashes when using the JIT with debugging
313 turned on, this fixes it.
315 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
317 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
319 2002-09-05 Martin Baulig <martin@gnome.org>
321 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
322 which is read by the debugger.
324 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

336 * debug-dwarf2-plus.c: Removed.
338 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
339 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
340 `mono_symfile' to `symfile'.
342 * debug.c (mono_debug_open): Replaced the assembly argument with a
343 file name argument; you can now call this before loading the assembly.
344 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
345 we now use MonoSymbolFileLineNumberEntry's and a separate address array
346 instead; splitted out all MonoSymbolFileLineNumberEntry code into
347 debug_generate_il_offsets() and debug_update_il_offsets().
348 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
349 created when reading the symbol file or from debug_load_method_lines().
350 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
352 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

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

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

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

449 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
450 the algebraic form we are using. This also eliminated a silly overflow
451 of the intermediate result that was causing troubles.
453 2002-08-16 Nick Drochak <ndrochak@gol.com>
455 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
458 2002-08-15 Nick Drochak <ndrochak@gol.com>
460 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
461 will not fit in 64 bits. Fixes bug #27375.

476 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
478 * exception.c (arch_handle_exception): simply return and let the
479 libpthread/kernel restore the context. This should work on recent
480 versions of linuxthreads.
482 * jit.c (mono_runtime_install_handlers): switch back to use
483 sigaction from libpthreads. As long as this does not make problems
484 we should use this instead of syscall.
486 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
488 * jit.c: removed the createdelegate icall
489 (mono_analyze_stack): special case Array::Address()

501 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
503 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
505 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
506 than one page, it's necessary to allocate memory incrementally,
507 in page-size steps, performing stack-touch every time.
508 Also added LOCALLOC(CONST_I4) implementation.
510 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
512 * jit.c (mono_get_runtime_method): code cleanup
514 * x86.brg: we do not need to save EAX/ECX/EDX in stmt:

926 2002-05-21 Martin Baulig <martin@gnome.org>
928 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
929 file for all assemblies. Currently, the JIT doesn't put all methods
930 from a single assembly into a continuous region of memory. We were

1030 * exception.c (arch_handle_exception): EIP now points to the call
1031 instruction, not to the instruction after the call. This fixes the

1402 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1403 numbers, we still need to generate the IL offsets here. Emit line numbers
1404 for `prologue_end_offset' (the first line of actual code) and
1405 `epilogue_begin_offset' (the line of the method's closing brace).
1406 Don't crash if cfg->bblocks [i].forest is NULL.
1407 (mono_debug_add_method): Don't crash if we don't have line numbers.
1408 Initialize the newly added fields.
1410 * debug-stabs.c: Record first and last line, emit filename info at the

1413 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1414 emit line number info for the first and last line.
1416 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1450 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1451 we don't have line number information. Use `minfo->method_info.this_offset'
1452 instead of hardcoding 8.

1480 2002-03-23 Martin Baulig <martin@gnome.org>
1482 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1483 to do it before the X86_CMP.
1484 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1485 (reg: CLT (lreg, lreg)): Likewise.
1486 (reg: CLT_UN (lreg, lreg)): Likewise.

1516 removed everything which is already in MonoDebugMethodInfo.
1518 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1557 * debug.c (mono_debug_get_type): Recursively call this for all function members
1559 (mono_debug_add_method): Don't mangle function names, this must be done by the
1560 debugger backend if the debugging format needs mangled names.
1562 * debug-dwarf2.c: Improved support for classes, added member functions.
1564 2002-03-16 Martin Baulig <martin@gnome.org>
1566 * debug.c (mono_debug_get_type): Recursively call this for all members and
1567 parent classes of a class type.
1569 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1570 since GDB doesn't like Java very much.
1572 2002-03-16 Martin Baulig <martin@gnome.org>
1574 * debug-dwarf2.c: Added support for enums.
1576 2002-03-15 Martin Baulig <martin@gnome.org>

1597 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1599 (mono_debug_open_file): Added MonoDebugFormat argument.
1600 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1601 this function from GDB. It's now safe to call this function multiple times;
1602 it'll always write a complete debugging file.
1604 * debug.c: Splitted this file into a general part which remains in this file
1605 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1606 All public functions now call a corresponding format specific function.
1608 * debug.c: The following changes are private to debug.c:
1609 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1610 (record_line_number, debug_generate_method_lines): New private functions.
1611 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1612 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1613 mono_debug_open_assembly_dwarf2).
1614 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1615 now safe to call this function multiple times.
1616 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1617 returns an unique index for this type. It's used to ensure that we only write
1618 each class once to the debugging file.
1619 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1620 data structure, but don't directly write to the debugging file. This is done
1621 later from mono_debug_write_assembly().
1623 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1624 debugging output. Call mono_debug_close() on cleanup if necessary.
1626 2002-03-14 Martin Baulig <martin@gnome.org>
1628 * debug-private.h: New private header file.
1630 * debug-stabs.c: Added the stabs type generation stuff which was
1631 previously in debug.c.
1633 * debug-dwarf.c: Started to implement type support. We're currently
1634 only writing this most basic types to the dwarf file, but this will
1637 2002-03-13 Martin Baulig <martin@gnome.org>
1639 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1640 debugging code. They're now in CVS, but not yet used anywhere.
1642 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1644 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1645 macros, included new delegate code from Daniel Stodden.
1648 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1650 * jit.c: verify that corlib and runtime are in sync.
1652 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1654 * emit-x86.c, jit.c: use the debug-helpers facilities to
1655 describe and match a method when debugging.
1657 2002-03-10 Martin Baulig <martin@gnome.org>
1659 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1660 output, put a nop instruction at the start of all functions so that
1661 the adresses won't change when using --debug.
1663 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1664 the bytecode area, stabs needs a line number in the .il file. Use the
1665 new info->moffsets to get the line number.
1666 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1667 `moffsets' is an array of `total_lines' fields (total number of lines
1668 in the .il file); for each line in the .il field, this array contains
1669 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1670 of a method and 0 otherwise.
1671 (debug_load_method_lines): Read the whole .il file and initialize the
1672 info->moffsets field.
1674 2002-03-09 Martin Baulig <martin@gnome.org>
1676 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1677 the unnecessary CDQ instruction.
1679 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1681 * jit.c (mono_analyze_stack): only load addresses of value types
1682 on the runtime stack.
1684 2002-03-07 Duncan Mak <duncan@ximian.com>
1686 * Makefile.am: A small patch fixing errors in vpath-based builds
1687 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1688 committed for Daniel Stodden <stodden@in.tum.de>.

2301 * x86.brg: added some floating point trees
2303 * testjit.c (mono_compile_method): arguments on the runtime
2304 stack are at least 4 bytes
2306 * x86.brg: partly implemented 8,16 bit integers
2308 * testjit.c (get_address): mark basic blocks
2310 2001-09-18 Dietmar Maurer <dietmar@ximian.com>
2312 * x86.brg: added some rules to optimize code
2314 * testjit.c (get_address): use a binary search to get the address
2315 (main): added an option to debug the jit (-d)
2317 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2319 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2321 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2323 * testjit.c (mono_compile_method): Provide better error reporting.
2325 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2327 * testjit.c (tree_get_address): impl. to fix address bug
2328 (tree_get_address): make sure that we can only jump to the first
2329 instruction of a tree.
2331 * x86.brg: emit real code for calls
2333 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2335 (mono_compile_method): reversed argument order
2337 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2339 * x86.brg (stmt): don't emit unnecessary register moves
2341 * testjit.c (tree_allocate_regs): free registers earlier
2343 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
2345 * x86.brg: branch addresses are now resolved
2347 * testjit.c (compute_branches): compute address of branches
2349 * x86.brg: emit real x86 instructions
2351 * testjit.c: call objdump to disassemble the output
2353 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2355 * x86.brg: use the right offsets to access local variables
2358 * emit-x86.c: only save/restore callee saved registers if they are
2361 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2363 (mono_compile_method): changed the tree for mothod calls
2370 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2372 * x86.brg: Use Unix assembly syntax.
2374 * emit-x86.c: support code, should be moved
2376 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2377 inefficient at appends.
2379 * Renamed `create_new_leave' to `create_new_leaf'
