llvm-6502/lib/Target/Mips/MipsFrameLowering.h
Akira Hatanaka cdb3ba71ce Add definitions of two subclasses of MipsFrameLowering, Mips16FrameLowering and
MipsSEFrameLowering.

Implement MipsSEFrameLowering::hasReservedCallFrame. Call frames will not be
reserved if there is a call with a large call frame or there are variable sized
objects on the stack.
