2010-09-16When substituting sunkaddrs into indirect arguments an asm, we wereDale Johannesen
walking the asm arguments once and stashing their Values. This is wrong because the same memory location can be in the list twice, and if the first one has a sunkaddr substituted, the stashed value for the second one will be wrong (use-after-free). PR 8154. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114104 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-16It is possible, under specific circumstances involving ptrtoint ↵Owen Anderson
ConstantExpr's, for LVI to end up trying to merge a Constant into a ConstantRange. Handle this conservatively for now, rather than asserting. The testcase is more complex that I would like, but the manifestation of the problem is sensitive to iteration orders and the state of the LVI cache, and I have not been able to reproduce it with manually constructed or simplified cases. Fixes PR8162. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114103 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-16Change SPU register re-interpretations from OR to COPY_TO_REGCLASS instruction.Kalle Raiskila
This cleans up after the mess r108567 left in the CellSPU backend. ORCvt-instruction were used to reinterpret registers, and the ORs were then removed by isMoveInstr(). This patch now removes 350 instrucions of format: or $3, $3, $3 (from the 52 testcases in CodeGen/CellSPU). One case of a nonexistant or is checked for. Some moves of the form 'ori $., $., 0' and 'ai $., $., 0' still remain. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114074 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-16Use the value mapping provided by LiveIntervalMap. This simplifies the code aJakob Stoklund Olesen
great deal because we don't have to worry about maintaining SSA form. Unconditionally copy back to dupli when the register is live out of the split range, even if the live-out value was defined outside the range. Skipping the back-copy only makes sense when the live range is going to spill outside the split range, and we don't know that it will. Besides, this was a hack to avoid SSA update issues. Clear up some confusion about the end point of a half-open LiveRange. Methinks LiveRanges need to be closed so both start and end are included in the range. The low bits of a SlotIndex are symbolic, so a half-open range doesn't really make sense. This would be a pervasive change, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114043 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-15Since PassRegistry is currently a shared global object, it needs locking. ↵Owen Anderson
While it might intuitively seem that all the setup of this class currently happens at static initialization time, this misses the fact that some later events can cause mutation of the PassRegistrationListeners list, and thus cause race issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114036 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-15Add a InitSections method to the streamer interface.Rafael Espindola
The ELF implementation now creates text, data and bss to match the gnu as behavior. The text streamer still has the old MachO specific behavior since the testsuite checks that it will error when a directive is given before a setting the current section for example. A nice benefit is that -n is not required anymore when producing ELF files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114027 91177308-0d34-0410-b5e6-96231b3b80d8

VFP instructions use it for loading some constants, so implement that handling.
