and set the address as an opcode address or as a callable address. This is needed in various places in the thread plans to make sure that addresses that might be found in symbols or runtime might already have extra bits set (ARM/Thumb). The new functions are: bool Address::SetCallableLoadAddress (lldb::addr_t load_addr, Target *target); bool Address::SetOpcodeLoadAddress (lldb::addr_t load_addr, Target *target); SetCallableLoadAddress will initialize a section offset address if it can, and if so it might possibly set some bits in the address to make the address callable (bit zero might get set for ARM for Thumb functions). SetOpcodeLoadAddress will initialize a section offset address using the specified target and it will strip any special address bits if needed depending on the target. Fixed the ABIMacOSX_arm::GetArgumentValues() function to require arguments 1-4 to be in the needed registers (previously this would incorrectly fallback to the stack) and return false if unable to get the register values. The function was also modified to first look for the generic argument registers and then fall back to finding the registers by name. Fixed the objective trampoline handler to use the new Address::SetOpcodeLoadAddress function when needed to avoid address mismatches when trying to complete steps into objective C methods. Make similar fixes inside the AppleThreadPlanStepThroughObjCTrampoline::ShouldStop() function. Modified ProcessGDBRemote::BuildDynamicRegisterInfo(...) to be able to deal with the new generic argument registers. Modified RNBRemote::HandlePacket_qRegisterInfo() to handle the new generic argument registers on the debugserver side. Modified DNBArchMachARM::NumSupportedHardwareBreakpoints() to be able to detect how many hardware breakpoint registers there are using a darwin sysctl. Did the same for hardware watchpoints in DNBArchMachARM::NumSupportedHardwareWatchpoints(). llvm-svn: 131834 |
