Filippos Karapetis 7a68ee57b1 SCI: Always include the opcodeNames table, as it's used in VM hooks 2020-03-16 01:58:34 +02:00
Zvika Haramaty ac87c01895 SCI: debugger: disasm - added 'bcc' parameter, to use in C code 
'bcc' is based on 'bc', but prints in format that's can be used in
C code for patches - just copy and paste (without the address column).

sluicebox f73584f0e5 SCI: Fix disassembler crash on invalid property 
Fixes debugger crash when disassembling an instruction whose operand
is an invalid property. This occurs in LB2 floppy 1.0 script 720 in
sGetUp:changeState and sStepOnNail:changeState.

Filippos Karapetis 941869c466 SCI32: Remove reg32_t and use reg_t in all cases 
reg32_t was a transitive solution, before reg_t's were
adapted to use 32-bit addresses internally, and before
support for SCI3 was added. It was introduced as another
way to handle large script offsets in SCI3, and was only
used for the program counter (PC). It's no longer
needed, as we now support SCI3 script offsets using
reg_t's, so we can use make_reg32 in all cases where
we need to access offsets over 64KB

Willem Jan Palenstijn fab43f0f71 SCI: Fix offsets in disasm for multi-param opcodes 
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.

Willem Jan Palenstijn e2e3f7c4c5 SCI: Move bpk/logkernel to main breakpoint infrastructure 
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.

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 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.

   object/class names
3. Opcode arguments are visually aligned
