Member Function Documentation

◆ BehavesLikeZerothFrame()

virtual bool lldb_private::RegisterContext::BehavesLikeZerothFrame ( ) const
inlineprotectedvirtual

Indicates that this frame is currently executing code, that the PC value is not a return-pc but an actual executing instruction.

Some places in lldb will treat a return-pc value differently than the currently-executing-pc value, and this method can indicate if that should be done. The base class implementation only uses the frame index, but subclasses may have additional information that they can use to detect frames in this state, for instance a frame above a trap handler (sigtramp etc)..

◆ CalculateExecutionContext()

Reconstruct the object's execution context into sc.

The object should fill in as much of the ExecutionContextScope as it can so function calls that require a execution context can be made for the given object.

Parameters
[out]exe_ctxA reference to an execution context object that gets filled in.

◆ ConvertRegisterKindToRegisterNumber()

uint32_t RegisterContext::ConvertRegisterKindToRegisterNumber ( lldb::RegisterKind  kind,
uint32_t  num 
)
virtual

Convert from a given register numbering scheme to the lldb register numbering scheme.

There may be multiple ways to enumerate the registers for a given architecture. ABI references will specify one to be used with DWARF, the register numberings from process plugin, there may be a variation used for eh_frame unwind instructions (e.g. on Darwin), and so on. Register 5 by itself is meaningless - RegisterKind enumeration tells you what context that number should be translated as.

Inside lldb, register numbers are in the eRegisterKindLLDB scheme; arguments which take a register number should take one in that scheme.

eRegisterKindGeneric is a special numbering scheme which gives us constant values for the pc, frame register, stack register, etc., for use within lldb. They may not be defined for all architectures but it allows generic code to translate these common registers into the lldb numbering scheme.

This method translates a given register kind + register number into the eRegisterKindLLDB register numbering.

Parameters
[in]kindThe register numbering scheme (RegisterKind) that the following register number is in.
[in]numA register number in the 'kind' register numbering scheme.
Returns
The equivalent register number in the eRegisterKindLLDB numbering scheme, if possible, else LLDB_INVALID_REGNUM.

◆ GetPCForSymbolication()

bool RegisterContext::GetPCForSymbolication ( Address &  address)

Get an address suitable for symbolication.

When symbolicating – computing line, block, function – for a function in the middle of the stack, using the return address can lead to unexpected results for the user. A function that ends in a tail-call may have another function as the "return" address, but it will never actually return. Or a noreturn call in the middle of a function is the end of a block of instructions, and a DWARF location list entry for the return address may be a very different code path with incorrect results when printing variables for this frame.

At a source line view, the user expects the current-line indictation to point to the function call they're under, not the next source line.

The return address (GetPC()) should always be shown to the user, but when computing context, keeping within the bounds of the call instruction is what the user expects to see.

Parameters
[out]addressAn Address object that will be filled in, if a PC can be retrieved.
Returns
Returns true if the Address param was filled in.
