You can now access a frame in a thread using:
lldb.SBThread.frame[int] -> lldb.SBFrame object for a frame in a thread
Where "int" is an integer index. You can also access a list object with all of
the frames using:
lldb.SBThread.frames => list() of lldb.SBFrame objects
All SB objects that give out SBAddress objects have properties named "addr"
lldb.SBInstructionList now has the following convenience accessors for len() and
instruction access using an index:
insts = lldb.frame.function.instructions
for idx in range(len(insts)):
print insts[idx]
Instruction lists can also lookup an isntruction using a lldb.SBAddress as the key:
pc_inst = lldb.frame.function.instructions[lldb.frame.addr]
lldb.SBProcess now exposes:
lldb.SBProcess.is_alive => BOOL Check if a process is exists and is alive
lldb.SBProcess.is_running => BOOL check if a process is running (or stepping):
lldb.SBProcess.is_running => BOOL check if a process is currently stopped or crashed:
lldb.SBProcess.thread[int] => lldb.SBThreads for a given "int" zero based index
lldb.SBProcess.threads => list() containing all lldb.SBThread objects in a process
SBInstruction now exposes:
lldb.SBInstruction.mnemonic => python string for instruction mnemonic
lldb.SBInstruction.operands => python string for instruction operands
lldb.SBInstruction.command => python string for instruction comment
SBModule now exposes:
lldb.SBModule.uuid => uuid.UUID(), an UUID object from the "uuid" python module
lldb.SBModule.symbol[int] => lldb.Symbol, lookup symbol by zero based index
lldb.SBModule.symbol[str] => list() of lldb.Symbol objects that match "str"
lldb.SBModule.symbol[re] => list() of lldb.Symbol objecxts that match the regex
lldb.SBModule.symbols => list() of all symbols in a module
SBAddress objects can now access the current load address with the "lldb.SBAddress.load_addr"
property. The current "lldb.target" will be used to try and resolve the load address.
Load addresses can also be set using this accessor:
addr = lldb.SBAddress()
addd.load_addr = 0x123023
Then you can check the section and offset to see if the address got resolved.
SBTarget now exposes:
lldb.SBTarget.module[int] => lldb.SBModule from zero based module index
lldb.SBTarget.module[str] => lldb.SBModule by basename or fullpath or uuid string
lldb.SBTarget.module[uuid.UUID()] => lldb.SBModule whose UUID matches
lldb.SBTarget.module[re] => list() of lldb.SBModule objects that match the regex
lldb.SBTarget.modules => list() of all lldb.SBModule objects in the target
SBSymbol now exposes:
lldb.SBSymbol.name => python string for demangled symbol name
lldb.SBSymbol.mangled => python string for mangled symbol name or None if there is none
lldb.SBSymbol.type => lldb.eSymbolType enum value
lldb.SBSymbol.addr => SBAddress object that represents the start address for this symbol (if there is one)
lldb.SBSymbol.end_addr => SBAddress for the end address of the symbol (if there is one)
lldb.SBSymbol.prologue_size => pythin int containing The size of the prologue in bytes
lldb.SBSymbol.instructions => SBInstructionList containing all instructions for this symbol
SBFunction now also has these new properties in addition to what is already has:
lldb.SBFunction.addr => SBAddress object that represents the start address for this function
lldb.SBFunction.end_addr => SBAddress for the end address of the function
lldb.SBFunction.instructions => SBInstructionList containing all instructions for this function
SBFrame now exposes the SBAddress for the frame:
lldb.SBFrame.addr => SBAddress which is the section offset address for the current frame PC
These are all in addition to what was already added. Documentation and website
updates coming soon.
