Detailed Description

Transforms the IR for a function to run in the target.

Once an expression has been parsed and converted to IR, it can run in two contexts: interpreted by LLDB as a DWARF location expression, or compiled by the JIT and inserted into the target process for execution.

IRForTarget makes the second possible, by applying a series of transformations to the IR which make it relocatable. These transformations are discussed in more detail next to their relevant functions.

◆ RewriteObjCSelector()

bool IRForTarget::RewriteObjCSelector ( llvm::Instruction * selector_load )

private

A basic block-level pass to find all Objective-C method calls and rewrite them to use sel_registerName instead of statically allocated selectors.

The reason is that the selectors are created on the assumption that the Objective-C runtime will scan the appropriate section and prepare them. This doesn't happen when code is copied into the target, though, and there's no easy way to induce the runtime to scan them. So instead we get our selectors from sel_registerName. Replace a single selector reference

Parameters

[in] selector_load The load of the statically-allocated selector.

Returns: True on success; false otherwise

◆ RewritePersistentAlloc()

bool IRForTarget::RewritePersistentAlloc ( llvm::Instruction * persistent_alloc )

private

A basic block-level pass to find all newly-declared persistent variables and register them with the ClangExprDeclMap.

This allows them to be materialized and dematerialized like normal external variables. Before transformation, these persistent variables look like normal locals, so they have an allocation. This pass excises these allocations and makes references look like external references where they will be resolved – like all other external references – by ResolveExternals(). Handle a single allocation of a persistent variable

Parameters

[in] persistent_alloc The allocation of the persistent variable.

Returns: True on success; false otherwise

◆ TurnGuardLoadIntoZero()

void IRForTarget::TurnGuardLoadIntoZero ( llvm::Instruction * guard_load )

private

A basic block-level pass to excise guard variables from the code.

The result for the function is passed through Clang as a static variable. Static variables normally have guard variables to ensure that they are only initialized once. Rewrite a load to a guard variable to return constant 0.

Parameters

[in] guard_load The load instruction to zero out.

◆ UnfoldConstant()

		llvm::Function *	llvm_function,
		FunctionValueCache &	value_maker,
		FunctionValueCache &	entry_instruction_finder,
		lldb_private::Stream &	error_stream
	)

staticprivate

UnfoldConstant operates on a constant [Old] which has just been replaced with a value [New].

We assume that new_value has been properly placed early in the function, in front of the first instruction in the entry basic block [FirstEntryInstruction].

UnfoldConstant reads through the uses of Old and replaces Old in those uses with New. Where those uses are constants, the function generates new instructions to compute the result of the new, non-constant expression and places them before FirstEntryInstruction. These instructions replace the constant uses, so UnfoldConstant calls itself recursively for those.

Returns: True on success; false otherwise
