2016-07-02SCI: Remove unexpected side effect from ExecStack constructorWillem Jan Palenstijn
The ExecStack constructor set argp[0] to argc before. This is now moved to the caller, to make this action more explicit.
2016-07-02SCI: Improve kernel subfunction loggingWillem Jan Palenstijn
ExecStack now stores the kernel call number as well as the subfunction. This allows kStub and backtraces to log the actual subfunction called. The kernel call number in ExecStack used to be stored in the debugSelector field. It now has its own field, to avoid confusion.
2016-02-05SCI: Clean up the op_infoToa and op_superToa SCI3 opcodesFilippos Karapetis
2014-02-18SCI: Make GPL headers consistent in themselves.Johannes Schickel
2012-07-04SCI: make g_base_opcode_formats and SciOpcodes a bit more readableFilippos Karapetis
2012-06-23SCI: Change the program counter (PC) to be a 32-bit variableFilippos Karapetis
This is needed for future support of large SCI3 scripts. The program counter is isolated and does not interfere with other parts of the VM, plus it does not get stored in saved games, so it's pretty straightforward to convert
2012-06-18SCI: Add setter/getter methods to reg_t'sFilippos Karapetis
No functionality change has been made with this commit. This avoids setting and getting the reg_t members directly, and is the basis of any future work on large SCI3 scripts (larger than 64KB)

svn-id: r49513
2010-06-06Now that EngineState is not deleted when loading games, we can move some ↵Filippos Karapetis
more state-related variables to it, and remove several FIXME's about non-const global variables. Also, the entries in the data stack are now deleted when loading (fixes a memory leak - thanks to digitall for this). svn-id: r49465

kSetCursor() kernel function semantics svn-id: r49408

Segment manager functions allocateHunkEntry, getHunkPointer and freeHunkEntry are used directly (which are more descriptive, anyway) - Replaced the GET_SEGMENT macro by a method of the segment manager - Removed the unused reference to the created hunk in allocateHunkEntry(), only the reg_t reference to it is returned now svn-id: r49078

svn-id: r47874
2010-02-03Initial implementation of text drawing for SCI2 (it's a hack for now, done ↵Filippos Karapetis
the "SCI0-SCI11" way, and text splitting is wrong...) svn-id: r47838
2010-02-03SCI: Make add_exec_stack_entry & add_exec_stack_varselector static / privateMax Horn

(untested) svn-id: r47824
2010-01-28Detect whether to use the modified SCI2 or SCI2.1 kernel table based on the ↵Matthew Hoops
kDoSound call used in Sound::play(), which fixes at least my version of KQ7 - probably others. The kernel table initialization now occurs after the script signatures are adjusted as we need it adjusted before checking through Sound::play for the kDoSound call. svn-id: r47645
