git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127369 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Change the definition of TargetRegisterInfo::getCrossCopyRegClass to be moreEvan Cheng
flexible. If it returns a register class that's different from the input, then that's the register class used for cross-register class copies. If it returns a register class that's the same as the input, then no cross- register class copies are needed (normal copies would do). If it returns null, then it's not at all possible to copy registers of the specified register class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127368 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-09LLVM combines the offset mode of A8.6.199 A1 & A2 into STRBT.Johnny Chen
The insufficient encoding information of the combined instruction confuses the decoder wrt UQADD16. Add extra logic to recover from that. Fixed an assert reported by Sean Callanan git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127354 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-09Make physreg coalescing independent on the number of uses of the virtual ↵Jakob Stoklund Olesen
register. The damage done by physreg coalescing only depends on the number of instructions the extended physreg live range covers. This fixes PR9438. The heuristic is still luck-based, and physreg coalescing really should be disabled completely. We need a register allocator with better hinting support before that is possible. Convert a test to FileCheck and force spilling by inserting an extra call. The previous spilling behavior was dependent on misguided physreg coalescing decisions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127351 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Delete a test case that is very sensitive to coalescer behavior.Jakob Stoklund Olesen
The test is derived from an old miscompilation of MultiSource/Benchmarks/VersaBench/8b10b which is run regularly, so we are not losing coverage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127350 91177308-0d34-0410-b5e6-96231b3b80d8

When ExactBECount is a constant, use it for MaxBECount. When MaxBECount cannot be computed, replace it with ExactBECount. Fixes PR9424. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127342 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-09Fix a crasher introduced by r127317 that is seen on the bots when using anCameron Zwarich
alloca as both integer and floating-point vectors of the same size. Bugpoint is not cooperating with me, but I'll try to find a manual testcase tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127320 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Add another micro-optimization. Apologies for the lack of refactoring, but INick Lewycky
gave up when I realized I couldn't come up with a good name for what the refactored function would be, to describe what it does. This is PR9343 test12, which is test3 with arguments reordered. Whoops! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127318 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-09Add support to scalar replacement for partial vector accesses of an alloca, e.g.Cameron Zwarich
a union of a float, <2 x float>, and <4 x float>. This mostly comes up with the use of vector intrinsics, especially in NEON when programmers know the layout of the register file. This enables codegen to eliminate a lot of the subregister traffic it would otherwise generate. This commit only enables this for a small number of floating-point cases, but a lot more integer cases. I assume this is okay for all ports, but I did not do extensive testing of the quality of code involving i512 vectors and the like. If there is a use case where this generates worse code than before, let me know and we can scale it back. This fixes <rdar://problem/9036264>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127317 91177308-0d34-0410-b5e6-96231b3b80d8
