* Add a separate unrolling threshold when the current function is being ↵Owen Anderson2010-09-071-4/+20
| | | | | | | | | | | optimized for size. The threshold value of 50 is arbitrary, and I chose it simply by analogy to the inlining thresholds, where the baseline unrolling threshold is slightly smaller than the baseline inlining threshold. This could undoubtedly use some tuning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113306 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't add <imp-def> operands during register rewriting.Jakob Stoklund Olesen2010-09-071-16/+9
| | | | | | | | | | | | | | LiveIntervals already adds <imp-def> operands for super-registers when a subreg def defines the whole register. Thus, it is not necessary to do it again when rewriting. In fact, the super-register imp-defs caused miscompilations because the late scheduler couldn't see that the super-register was read. We still add super-reg <imp-use,kill> operands when rewriting virtuals to physicals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113299 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | register must be one of the destination registers for the load. Otherwise, the tLDM instruction will write-back to the base register, which isn't what's desired (otherwise, we'd have a t2LDM_UPD instead). rdar://8394087 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113297 91177308-0d34-0410-b5e6-96231b3b80d8
