//===-- PhyRegAlloc.cpp ---------------------------------------------------===//
//
// Register allocation for LLVM.
// Traditional graph-coloring global register allocator currently used
// by the SPARC back-end.
//
// NOTE: This register allocator has some special support
// for the Reoptimizer, such as not saving some registers on calls to
// the first-level instrumentation function.
//
// NOTE 2: This register allocator can save its state in a global
// variable in the module it's working on. This feature is not
// thread-safe; if you have doubts, leave it turned off.
