Push a finalization callback on the finalization stack. NOTE: Temporary solution until Clang CG is gone.

Check whether the range [Low,High] fits in a machine word.

readGCDAFormat - Check GCDA signature is valid at the beginning of buffer.

readGCNOFormat - Check GCNO signature is valid at the beginning of buffer.

readGCOVVersion - Read GCOV version.

Read and validate the file header.

readsReg - Returns true if this operand reads the previous value of its register. A use operand with the <undef> flag set doesn't read its register.

Return true if the MachineInstr reads the specified register. If TargetRegisterInfo is passed, then it also checks if there is a read of a super-regis

Return true if the MachineInstr reads the specified virtual register. Take into account that a partial define is a read-modify-write operation.

Convenience function for recomputing live-in's for \p MBB.

Re-attach an edge to its nodes. Adds an edge that had been previously disconnected back into the adjacency set of the nodes that the edge connects.

Record that the critical edge (FromBB, ToBB) has been split with NewBB. This is best to use this method instead of directly update the underlying info

Compute a reduction order for the graph by iteratively applying PBQP reduction rules. Locally optimal rules are applied whenever possible (R0, R1, R2)

Generate code to reduce the loop iteration by one and check if the loop is finished. Return the value/register of the new loop count. We need this f

Return true if it is profitable to convert a select of FP constants into a constant pool load whose address depends on the select condition. The param

Update this MemSDNode's MachineMemOperand information to reflect the alignment of NewMMO, if it has a greater alignment. This must only be used when t

reg_empty - Return true if there are no instructions using or defining the specified register (it may be live-in).

reg_nodbg_empty - Return true if the only instructions using or defining Reg are Debug instructions.
