Nunuhara Cabbage	9ede2d7af9	debugger: add vm-state command ... Add vm-state command, which prints disassembly around the current instruction pointer and the current contents of the stack. It was necessary to change how breakpoints are implemented for this. When adding a breakpoint, the original opcode now remains in the instruction stream, bitwise-or'd with BREAKPOINT. A hash table indexed by address is used to store breakpoint objects.	2022-04-14 09:08:57 -07:00
Nunuhara Cabbage	caf11f3991	Debugger improvements ... * Add "frame" command to change the current frame. * Add "members" command to print struct members for current frame (if it's a method frame). * Support printing member variables (e.g. "this.var") in the "print" command.	2022-04-12 19:18:05 -07:00
Nunuhara Cabbage	9fbc9ec5b7	Implement simple command-based debugger interface ... Add a new debugger interface using a simple command language. This is less powerful than the scheme interface (which still exists) but more ergonomic for interactive debugging. This debugger has no external dependencies (it will however use readline if available) and is included in builds by default. A sample interaction might look like: xsystem4 --debug /path/to/game dbg(cmd)> breakpoint bar Set breakpoint at function 'bar' (0x00001234) dbg(cmd)> continue Hit breakpoint at function 'bar' (0x00001234) dbg(cmd)> backtrace #0 0x00001234 in bar #1 0x00002222 in foo #2 0x00004444 in main dbg(cmd)> locals [0] i: 2 [1] s: "baz" dbg(cmd)> locals 1 [0] j: 3 [1] obj: { m_i = 0; m_s = "" } dbg(cmd)> quit	2022-04-01 19:38:55 -07:00
