2013-01-26X86: Do splat promotion later, so the optimizer can chew on it first.Benjamin Kramer
This catches many cases where we can emit a more efficient shuffle for a specific mask or when the mask contains undefs. Once the splat is lowered to unpacks we can't do that anymore. There is a possibility of moving the promotion after pshufb matching, but I'm not sure if pshufb with a mask loaded from memory is faster than 3 shuffles, so I avoided that for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173569 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-25Remove some introspection functions.Bill Wendling
The 'getSlot' function and its ilk allow introspection into the AttributeSet class. However, that class should be opaque. Allow access through accessor methods instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173522 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-25Initial implementation of PPCTargetTransformInfoHal Finkel
This provides a place to add customized operation cost information and control some other target-specific IR-level transformations. The only non-trivial logic in this checkin assigns a higher cost to unaligned loads and stores (covered by the included test case). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173520 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-25In this patch, we teach X86_64TargetMachine that it has a ILP32Eli Bendersky
(defined by the x32 ABI) mode, in which case its pointers are 32-bits in size. This knowledge is also added to X86RegisterInfo that now returns the appropriate registers in getPointerRegClass. There are many outcomes to this change. In order to keep the patches separate and manageable, we start by focusing on some simple testable cases. The patch adds a test with passing a pointer to a function - focusing on the difference between the two data models for x86-64. Another test is added for handling of 'sret' arguments (and functionality is added in X86ISelLowering to make it work). A note on naming: the "x32 ABI" document refers to the AMD64 architecture (in LLVM it's distinguished by being is64Bits() in the x86 subtarget) with two variations: the LP64 (default) data model, and the ILP32 data model. This patch adds predicates to the subtarget which are consistent with this naming scheme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173503 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-25This patch aims to reduce compile time in LegalizeTypes by using SmallDenseMap,Preston Gurd
with an initial number of elements, instead of DenseMap, which has zero initial elements, in order to avoid the copying of elements when the size changes and to avoid allocating space every time LegalizeTypes is run. This patch will not affect the memory footprint, because DenseMap will increase the element size to 64 when the first element is added.

2013-01-25Switch this code away from Value::isUsedInBasicBlock. That code eitherChandler Carruth
loops over instructions in the basic block or the use-def list of the value, neither of which are really efficient when repeatedly querying about values in the same basic block. What's more, we already know that the CondBB is small, and so we can do a much more efficient test by counting the uses in CondBB, and seeing if those account for all of the uses. Finally, we shouldn't blanket fail on any such instruction, instead we should conservatively assume that those instructions are part of the cost. Note that this actually fixes a bug in the pass because isUsedInBasicBlock has a really terrible bug in it. I'll fix that in my next commit, but the fix for it would make this code suddenly take the compile time hit I thought it already was taking, so I wanted to go ahead and migrate this code to a faster & better pattern. The bug in isUsedInBasicBlock was also causing other tests to test the wrong thing entirely: for example we weren't actually disabling speculation for floating point operations as intended (and tested), but the test passed because we failed to speculate them due to the isUsedInBasicBlock failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173417 91177308-0d34-0410-b5e6-96231b3b80d8
