This code was assuming that retval points to the start of the next
instruction, which is only true if the current parameter is the last
one. This fixes op_call printing.
See matchKernelBreakpointPattern() for samples. The main envisioned use is
DoSound*,!DoSoundUpdateCues
to match all DoSound sub-functions except DoSoundUpdateCues.
This changes the syntax for bpk and logkernel:
Enable breakpoint on kernel call:
bpk FrameOut
Enable logging for kernel call:
bpk FrameOut log
For backward compatibility this has an alias: logkernel FrameOut
Removing a kernel call breakpoint is done with bp_del/bc now.
0f9c33e02f1cb2c740c1eb0dcaad96dd22ec29e7 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.
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).
Learning the bytecode for file op is necessary when creating
workaround signatures, as the signature-finding mechanism does not
currently ignore line/file instructions.
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
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
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)
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)
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]*$//'
