2009-07-19SCI: check shouldQuit() in main loopWillem Jan Palenstijn
svn-id: r42609
2009-07-18SCI: Fix breakpointsWillem Jan Palenstijn
svn-id: r42599
2009-07-18SCI: Fix stepping in debuggerWillem Jan Palenstijn
svn-id: r42587
2009-07-11Moved the kernel and the vocabulary outside of the engine state (they're ↵Filippos Karapetis
static data, which never changes during a game) svn-id: r42398
2009-07-11Fixed regression in the script parser from commit 42260Filippos Karapetis
svn-id: r42371
2009-07-08- Moved printObject inside the Console classFilippos Karapetis
- Enabled the parts where disassemble() is called svn-id: r42263
2009-07-08Some cleanup for the script debugger code:Filippos Karapetis
- Renamed struct DebugState to ScriptState and r_amp_rest to restAdjust inside EngineState. Changed restAdjust to be a uint16 (actually it is a uint16, but it was being casted back and forth from an unsigned integer, so this clears up its type and size) - Moved the script state variables from inside the run_vm() into the ScriptState struct, so that they can be accessed by the console commands and the script debugger all the time, and removed the weird isValid code svn-id: r42260
2009-07-07Added auto-detection for games with older headers for script blocks, and ↵Filippos Karapetis
removed game flag GF_SCI0_OLD svn-id: r42211
2009-07-07Added a SCI1.1 case in the lofss opcode, like in the lofsa opcode ↵Filippos Karapetis
(essentially, lofss and lofsa both load an offset, with lofsa loading it in the accumulator and lofss in the stack). lofss is rarely used in SCI1.1 games, which explains why no lofss-related crashes have been observed in SCI1.1 svn-id: r42209
2009-07-06Replaced sciprintf() calls with printf, DebugPrintf, warning and error callsFilippos Karapetis
svn-id: r42167
2009-07-05SCI1 games with absolute parameters to lofs instructions are automatically ↵Filippos Karapetis
detected now. Removed the GF_SCI1_LOFSABSOLUTE game flag svn-id: r42118
2009-07-03Replaced script_error and CORE_ERROR with error()Filippos Karapetis
svn-id: r42079
2009-07-03- Pushed debugstate into debug.hFilippos Karapetis
- When an error occurs, manipulate the execution stack before error() opens the console inside getDebugger(), like FreeSCI did. Added another method for obtaining the SCI console for use by the engine itself. svn-id: r42062
2009-07-02Moved some more debug state related variables in the DebugState structFilippos Karapetis
svn-id: r42044
2009-06-18PatchMax Horn
svn-id: r41647
2009-06-07SCI: Got rid of g_EngineStateMax Horn
svn-id: r41359
2009-06-07SCI: Moved resource36 handling into resource manager.Walter van Niftrik
svn-id: r41349
2009-06-07SCI: Fixed the broken SciEngine::pauseEngineIntern code by ensuring that ↵Max Horn
SciEngine::_gamestate is updated whenever the EngineState gets changed (due to loading a savestate) svn-id: r41346
2009-06-06Store long-term pointers to object variables in a new ObjVarRef struct.Willem Jan Palenstijn
Storing them as reg_t* could cause the pointers to become invalid when they pointed into CloneTable since CloneTable can be re-allocated. svn-id: r41220
2009-06-05Moved some more debug commands to ScummVM's coneole and removed some unused codeFilippos Karapetis
svn-id: r41198
2009-06-04SCI: Renamed EngineState::flags and version to _flags and _version ↵Max Horn
(following our conventions); also slightly changed the EngineState constructor to init _version & _flags, and used this to make them constant svn-id: r41177
2009-06-04SCI: Renamed _kfuncTable -> _kernelFuncs; and simplified/streamlined the ↵Max Horn
kernel func map in kernel.cpp a bit svn-id: r41176
2009-06-04SCI: Renamed various debug related global variables to have a g_ prefix; and ↵Max Horn
moved any 'extern' decls of them into a new header file svn-id: r41163
2009-06-04Turned debug_weak_validations on by default again, as apparently some games ↵Filippos Karapetis
like SQ3 fail in some validations (e.g. when loading). Also, fixed a potential out of bounds access when copying the value of __FILE__ into a buffer (as its value can be quite long in some cases). svn-id: r41154
2009-06-03- Sorted the console commands a bit more Filippos Karapetis
- Removed the commands which manipulated variables and turned them into debug variables instead - Rewrote help so that it's more organized and easier to read - Unified the debug variable names svn-id: r41136
2009-06-02Moved some more console commands to ScummVM's debug consoleFilippos Karapetis
svn-id: r41129
2009-06-02Moved some more console commands to ScummVM's debug consoleFilippos Karapetis
svn-id: r41126
2009-06-02Removed the gfxw_new_visual and gfxw_new_port wrappers, moved _kfuncTable ↵Filippos Karapetis
inside the Kernel class and moved gfxw_find_port inside the GfxVisual struct svn-id: r41125
2009-06-01Split the kernel functions away from the vocabulary functions (WIP, ↵Filippos Karapetis
saving/loading is broken) svn-id: r41101
2009-05-31Removed script_error_flag and script_debug_flag, which were used to error ↵Filippos Karapetis
out if something went wrong and open the debugger console. Changed all the places where they were used to error() out instead, as ScummVM's debugger console can open on error() svn-id: r41073
2009-05-31- Further objectification of the SCI vocabulary functionsFilippos Karapetis
- Rewrote the sci_opcodes enum so that it's easier to read - Made the engine error out if data is sent to an invalid selector (which is a fatal condition) svn-id: r41069
2009-05-31The error() and warning() functions add ! and newline automatically. (I didn'tTorbjörn Andersson
look at debug() and debugC(), since I'm really bored with this now. :-) svn-id: r41061
2009-05-31More objectification of the Vocabulary functionsFilippos Karapetis
svn-id: r41057
2009-05-30Started objectifying the vocabulary functions (WIP)Filippos Karapetis
svn-id: r41051
2009-05-30- Removed debug_mode from the engine stateFilippos Karapetis
- Turned all SCIkwarn and SCIkdebug functions to ScummVM's debugC function - Placed some debug code in appropriate defines: DEBUG_PARSER, DEBUG_AVOIDPATH and DEBUG_SOUND - Removed the "debuglog" command and the "script_checkloads_flag" and "sci_debug_flags" variables svn-id: r41033
2009-05-29SCI: Converted several fprintf(stderr) calls to warning/error (the remaining ↵Max Horn
fprintf calls should probably be replaced by suitable debug/debugC/debugN invocations) svn-id: r40993
2009-05-28SCI: Fix potential dangling pointer more robustly,Willem Jan Palenstijn
by changing the executionStack implementation to a list. svn-id: r40971
2009-05-28SCI: Merged SfxPlayer/NewPlayer code into sfx/core.cppMax Horn
svn-id: r40965
2009-05-28SCI: Fix potential dangling pointer after reallocationWillem Jan Palenstijn
svn-id: r40963
2009-05-21Removed the PREG, PSTK, IS_NULL_REG and REG_EQ definesFilippos Karapetis
svn-id: r40767
2009-05-19SCI: Some debugger fixes and cleanup.Walter van Niftrik
svn-id: r40732
2009-05-19SCI: Cleanup/paranoia checksMax Horn
svn-id: r40711
2009-05-18SCI: Got rid of EngineState::execution_stack_pos; overally, the resulting ↵Max Horn
code should be even stricter in detecting invalid VM stack access (and some bugs when loading saves might be fixed now...) svn-id: r40694
2009-05-18SCI: Replaced SegManager::getHeap() by Script::getHeap()Max Horn
svn-id: r40683
2009-05-17SCI: LSL6 invalid selector workaround is now always active, not just atWalter van Niftrik
startup. Added support for mirrored pic drawing. svn-id: r40648
2009-05-16SCI: Allow the VM to continue when the invalid selector access occurs at the ↵Walter van Niftrik
start of LSL6. svn-id: r40627
2009-05-15- Moved all the files out of /sci/scicore and into /sciFilippos Karapetis
- Moved /scicore/sciconsole.h into /engine, and renamed /engine/scriptconsole.cpp to /engine/sciconsole.cpp svn-id: r40608
2009-05-15SCI: Got rid of SEG_ID/SCRIPT_IDMax Horn
svn-id: r40599
2009-05-15SCI: Added SegManager::getScriptIfLoaded() methodMax Horn
svn-id: r40598
2009-05-15SCI: Turned several script related SegManager methods into Script methodsMax Horn
svn-id: r40597
