Willem Jan Palenstijn cb69d10e96 SCI: Add underscores to Breakpoint member variables 2017-06-10 21:32:35 +02:00

Willem Jan Palenstijn e9867356f5 SCI: Handle selector read/write breakpoints from opcodes 2017-06-10 21:32:35 +02:00
Willem Jan Palenstijn 3554875c7a SCI: Fix wildcard selector breakpoints 
0f9c33e02f in 2011 broke selector
breakpoints of the type "ObjName::", which previously caught all
selector sends of the named object.

Thanks to TMM and snover for noticing.

Colin Snover a2d7851e4d SCI32: Improve disassembly output of SCI3 property opcodes 
Since SCI3 scripts use selectors instead of offsets as operands
to property-related opcodes, the disassembler can look up and
display property names everywhere (unlike SCI2.1 and earlier,
which need to know the object being operated on to look up the
correct selector for a given offset).

Colin Snover 61fba94139 SCI: Remove dead code in Script_Offset disassembler 
Script_Offset is only ever used for lofsa/lofss opcodes.

Colin Snover 9e7c75cc79 SCI: Avoid crashing when disassembling a call with a bad object 
lookupSelector will raise an error if the passed object ID is
invalid.

Colin Snover be14778b2b SCI: Ensure bytecode/BWT for "file" op is also printed 
Learning the bytecode for file op is necessary when creating
workaround signatures, as the signature-finding mechanism does not
currently ignore line/file instructions.

Colin Snover 4814682d5f SCI: Improve disassembly output 
1. pushi opcode now displays decimal value and selector value (if
   one exists) in-line
2. lofsa, lofss, and super opcodes now display resolved
   object/class names
3. Opcode arguments are visually aligned

Johannes Schickel 1c6112e121 SCI: Introduce accessors for SegmentObjTable entries. 
This makes code not use _table directly whenever possible. An exception is the
save game code which is not easy to adapt due to design deficiencies.

Filippos Karapetis 20b6770808 SCI: Change the program counter (PC) to be a 32-bit variable 
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

Filippos Karapetis c075aafddb SCI: Add support for the debug opcode "file" in our script dissassembler

Filippos Karapetis 065e83e44f SCI: Store script sizes in 32-bit integers 
Since scripts can be larger than 64KB, and getBufSize() returns a 32-bit
integer, adapt variables that store script sizes accordingly

Filippos Karapetis 2b50824133 SCI: Add setter/getter methods to reg_t's 
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)

Tarek Soliman a4798602d7 JANITORIAL: Fix missing whitespace in pointer cast 
find -name '*.h' -or -name '*.cpp' | xargs sed -r -i 's@\(([A-Za-z0-9]+)\*\)@(\1 *)@g'

This seems to have caught some params as well which is not undesirable IMO.
It also caught some strings containing this which is undesirable so I
excluded them manually. (engines/sci/engine/kernel_tables.h)

Max Horn 88913c0139 ALL: Remove trailing whitespaces 
This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
  git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'

not stop at an intermediate ret opcode.
