Chris Lattner 929d4a8bb5 * Add a useful file comment
* Move InsertPrologEpilogCode class to PrologEpilogCodeInserter.cpp
   -> Among other things, this eliminates the need for the minstrVec static
      global array.

2002-04-09 05:21:26 +00:00
Chris Lattner f8a9bfbc03 Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the
new PrologEpilogCodeInserter.cpp file, and include the bodies of the
GetInstructionsFor(Prolog|Epilog) functions from SparcInstrSelection.cpp
into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.
