2006-09-28"Once more into the breach, dear friends, once more, or fill the wall upBill Wendling
with our English dead." No! Really! Serious this time...It was how the vreg uses were being adjusted that was causing hte Olden tests to fail. I corrected this and the Olden and Regression tests all passed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30644 91177308-0d34-0410-b5e6-96231b3b80d8

2006-09-28re-re-revert this, back to the right revision. It currently breaks bisort/mstChris Lattner
in olden among others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30637 91177308-0d34-0410-b5e6-96231b3b80d8
2006-09-28PEI now place callee save spills closest to the address pointed to by theEvan Cheng
incoming stack. This allows X86 backend to use push / pop in epilogue / prologue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30636 91177308-0d34-0410-b5e6-96231b3b80d8
2006-09-28- Added a hook processFunctionBeforeCalleeSaveScn(). This is called by PEI justEvan Cheng
before it determines which callee-save registers are to be spilled. This allows the target to make changes such as forcing certain physical registers to be spilled. - Modified comments. It's important to note the order of registers in the array returns by getCalleeSaveRegs() determines the order of callee save spill code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30635 91177308-0d34-0410-b5e6-96231b3b80d8

2006-09-27This:Chris Lattner
AggregateString += "\0\0"; Doesn't add two nuls to the AggregateString (for obvious reasons), which broke the asmprinter when the first character of an asm string was not literal text. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30625 91177308-0d34-0410-b5e6-96231b3b80d8
