Detailed Description

DWARF expression.

This is (almost) a DWARF expression that modifies the location of a variable, or the location of a single piece of a variable, or (when using DW_OP_stack_value) is the constant variable value.

TODO: Co-allocate the expression elements. TODO: Separate from MDNode, or otherwise drop Distinct and Temporary storage types.

◆ append()

DIExpression * DIExpression::append	(	const DIExpression *	Expr,
		ArrayRef< uint64_t >	Ops
	)

static

Append the opcodes Ops to DIExpr.

Unlike appendToStack, the returned expression is a stack value only if DIExpr is a stack value. If DIExpr describes a fragment, the returned expression will describe the same fragment.

◆ appendToStack()

DIExpression * DIExpression::appendToStack	(	const DIExpression *	Expr,

static

Convert DIExpr into a stack value if it isn't one already by appending DW_OP_deref if needed, and appending Ops to the resulting expression.

If DIExpr describes a fragment, the returned expression will describe the same fragment.

◆ createFragmentExpression()

Optional< DIExpression * > DIExpression::createFragmentExpression	(	const DIExpression *	Expr,
		unsigned	OffsetInBits,
		unsigned	SizeInBits
	)

static

Create a DIExpression to describe one part of an aggregate variable that is fragmented across multiple Values.

The DW_OP_LLVM_fragment operation will be appended to the elements of Expr. If Expr already contains a DW_OP_LLVM_fragment OffsetInBits is interpreted as an offset into the existing fragment.

Parameters

OffsetInBits	Offset of the piece in bits.
SizeInBits	Size of the piece in bits.

Returns: Creating a fragment expression may fail if Expr contains arithmetic operations that would be truncated.
