Inheritance diagram for lldb_private::ArchitectureRISCV:

Public Member Functions
llvm::StringRef	GetPluginName () override
void	OverrideStopInfo (Thread &thread) const override
	This is currently intended to handle cases where a program stops at an instruction that won't get executed and it allows the stop reason, like "breakpoint hit", to be replaced with a different stop reason like "no stop reason".
bool	IsValidTrapInstruction (llvm::ArrayRef< uint8_t > reference, llvm::ArrayRef< uint8_t > observed) const override
	Returns whether a given byte sequence is a valid trap instruction for the architecture.
Public Member Functions inherited from lldb_private::Architecture
virtual size_t	GetBytesToSkip (Symbol &func, const Address &curr_addr) const
	This method is used to get the number of bytes that should be skipped, from function start address, to reach the first instruction after the prologue.
virtual void	AdjustBreakpointAddress (const Symbol &func, Address &addr) const
	Adjust function breakpoint address, if needed.
virtual lldb::addr_t	GetCallableLoadAddress (lldb::addr_t addr, AddressClass addr_class=AddressClass::eInvalid) const
	Get load_addr as a callable code load address for this target.
virtual lldb::addr_t	GetOpcodeLoadAddress (lldb::addr_t addr, AddressClass addr_class=AddressClass::eInvalid) const
	Get load_addr as an opcode for this target.

virtual lldb::UnwindPlanSP	GetArchitectureUnwindPlan (lldb_private::Thread &thread, lldb_private::RegisterContextUnwind *regctx, std::shared_ptr< const UnwindPlan > current_unwindplan)
	Return an UnwindPlan that allows architecture-defined rules for finding saved registers, given a particular set of register values.

◆ IsValidTrapInstruction()

bool ArchitectureRISCV::IsValidTrapInstruction	(	llvm::ArrayRef< uint8_t >	reference,
		llvm::ArrayRef< uint8_t >	observed ) const

overridevirtual

Returns whether a given byte sequence is a valid trap instruction for the architecture.

Some architectures feature instructions that have immediates that can take on any value, resulting in a family of valid byte sequences. If the observed byte sequence is shorter than the reference then they are considered not to match, even if the initial bytes would match.

Reimplemented from lldb_private::Architecture.

Definition at line 34 of file ArchitectureRISCV.cpp.

◆ OverrideStopInfo()

void lldb_private::ArchitectureRISCV::OverrideStopInfo ( Thread & thread ) const

inlineoverridevirtual

This is currently intended to handle cases where a program stops at an instruction that won't get executed and it allows the stop reason, like "breakpoint hit", to be replaced with a different stop reason like "no stop reason".

This is specifically used for ARM in Thumb code when we stop in an IT instruction (if/then/else) where the instruction won't get executed and therefore it wouldn't be correct to show the program stopped at the current PC. The code is generic and applies to all ARM CPUs.
