bool MipsFrameLowering::hasFP

(

const MachineFunction &

MF

)

const [override, virtual]

hasFP - Return true if the specified function should have a dedicated frame pointer register. For most targets this is true only if the function has variable sized allocas or if frame pointer elimination is disabled.

Implements llvm::TargetFrameLowering.
