* Preserve subregs on PHI source operands. Patch by Krister Wombell!Jakob Stoklund Olesen2010-08-18
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111366 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a bug with insertelement on SPU. Kalle Raiskila2010-08-18
| | | | | | | | The previous algorithm in LowerVECTOR_SHUFFLE didn't check all requirements for "monotonic" shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111361 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove all traces of v2[i,f]32 on SPU. Kalle Raiskila2010-08-18
| | | | | | | | | The "half vectors" are now widened to full size by the legalizer. The only exception is in parameter passing, where half vectors are expanded. This causes changes to some dejagnu tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111360 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | "SPU Application Binary Interface Specification, v1.9" by IBM. Specifically: use r3-r74 to pass parameters and the return value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111358 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR7755: knowing something about an inval for a predChris Lattner2010-08-18

However, knowing something about the pred on the RHS shouldn't disable subsequent additions on the RHS from happening. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111349 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the rest of rdar://8318441 which happens when a raw_fd_ostreamChris Lattner2010-08-17
| | | | | | | | | | | | (e.g. errs()) fails in close() due to (e.g.) a broken pipe. As previously written, the had_error() flag would get set and then the raw_ostream dtor would report a fatal error. There is nothing the client can do about this and we have no way to report the error, so just eat it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111321 91177308-0d34-0410-b5e6-96231b3b80d8

* Tweak IVUsers' concept of "interesting" to exclude add recurrencesDan Gohman2010-08-17
| | | | | | | | | | where the step value is an induction variable from an outer loop, to avoid trouble trying to re-expand such expressions. This effectively hides such expressions from indvars and lsr, which prevents them from getting into trouble. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111317 91177308-0d34-0410-b5e6-96231b3b80d8
* Add materialization of virtual base registers for frame indices allocated intoJim Grosbach2010-08-17
| | | | | | | | | | | | | | | the local block. Resolve references to those indices to a new base register. For simplification and testing purposes, a new virtual base register is allocated for each frame index being resolved. The result is truly horrible, but correct, code that's good for exercising the new code paths. Next up is adding thumb1 support, which should be very simple. Following that will be adding base register re-use and implementing a reasonable ARM heuristic for when a virtual base register should be generated at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111315 91177308-0d34-0410-b5e6-96231b3b80d8

In LocalStackSlotAllocation, scan the function for frame index references to local frame indices and ask the target whether to allocate virtual frame base registers for any it encounters.
