Jim Grosbach 3d6cb88a64 Start of revamping the register scavenging in PEI. ARM Thumb1 is the driving ... interest for this, as it currently reserves a register rather than using the scavenger for matierializing constants as needed. Instead of scavenging registers on the fly while eliminating frame indices, new virtual registers are created, and then a scavenged collectively in a post-pass over the function. This isolates the bits that need to interact with the scavenger, and sets the stage for more intelligent use, and reuse, of scavenged registers. For the time being, this is disabled by default. Once the bugs are worked out, the current scavenging calls in replaceFrameIndices() will be removed and the post-pass scavenging will be the default. Until then, -enable-frame-index-scavenging enables the new code. Currently, only the Thumb1 back end is set up to use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82734 91177308-0d34-0410-b5e6-96231b3b80d8		2009-09-24 23:52:18 +00:00
