[llvm-commits] CVS: llvm/lib/CodeGen/MachineCodeForInstruction.cpp

[Chris Lattner]

Changes in directory llvm/lib/CodeGen:

MachineCodeForInstruction.cpp updated: 1.16 -> 1.17

---
Log message:

Do not find these ugly sparc-specific objects by using the annotation API on
instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!
