2010-09-16Change VLDMQ and VSTMQ to be pseudo instructions. They are expanded afterBob Wilson
register allocation to VLDMD and VSTMD respectively. This avoids using the dregpair operand modifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114047 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-16Fix a threaded LLVM bug due the need for operator= on reference counted ↵Owen Anderson
AttrListImpl's. It might be possible to implement this very carefully to allow a lock-free implementation while still avoiding illegal interleavings, but I haven't been able to figure one out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114046 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

moves. Previously, the immediate was printed as the encoded integer value, which is incorrect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114021 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-15move getRegisterNumbering() to out of ARMBaseRegisterInfo into the helperJim Grosbach
functions in ARMBaseInfo.h so it can be used in the MC library as well. For anything bigger than this, we may want a means to have a small support library for shared helper functions like this. Cross that bridge when we come to it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114016 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-15Add support for floating point immediates to MC instruction printing. ARMJim Grosbach
VFP instructions use it for loading some constants, so implement that handling. Not thrilled with adding a member to MCOperand, but not sure there's much of a better option that's not pretty fragile (like putting a double in the union instead and just assuming that's good enough). Suggestions welcome... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113996 91177308-0d34-0410-b5e6-96231b3b80d8

Recognize VLD1q64Pseudo as a stack slot load. Reject these if they are loading or storing a subregister. The API (and VirtRegRewriter) doesn't know how to deal with that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113985 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-15Remove LLVM_GLOBAL_VISIBILITY, which is unused, and was not working properly.Duncan Sands
The problem was that the test for whether a compiler supports it or not was inaccurate, but has to be accurate: LLVM_LOCAL_VISIBILITY is an optimization and not needed for correctness, so wrongly thinking a compiler doesn't support it is not a big deal, but LLVM_GLOBAL_VISIBILITY is for correctness, and not an optimization: getting it wrong is fatal: it needs to be set based on a configure test not testing the gcc version. Since dragonegg has moved to a different scheme, and it was the only user of LLVM_GLOBAL_VISIBILITY, just remove this macro. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113959 91177308-0d34-0410-b5e6-96231b3b80d8
