"the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions: -in vararg handling, registers are marked to be live, to not confuse the register scavenger -function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99819 91177308-0d34-0410-b5e6-96231b3b80d8
