// 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.
