2013-01-27BBVectorize: Better use of TTI->getShuffleCostHal Finkel
When flipping the pair of subvectors that form a vector, if the vector length is 2, we can use the SK_Reverse shuffle kind to get more-accurate cost information. Also we can use the SK_ExtractSubvector shuffle kind to get accurate subvector extraction costs. The current cost model implementations don't yet seem complex enough for this to make a difference (thus, there are no test cases with this commit), but it should help in future. Depending on how the various targets optimize and combine shuffles in practice, we might be able to get more-accurate costs by combining the costs of multiple shuffle kinds. For example, the cost of flipping the subvector pairs could be modeled as two extractions and two subvector insertions. These changes, however, should probably be motivated by specific test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173621 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-27When the legalizer is splitting vector shifts, the result may not have the ↵Benjamin Kramer
right shift amount type. Fix that by adding a cast to the shift expander. This came up with vector shifts on sse-less X86 CPUs. <2 x i64> = shl <2 x i64> <2 x i64> -> i64,i64 = shl i64 i64; shl i64 i64 -> i32,i32,i32,i32 = shl_parts i32 i32 i64; shl_parts i32 i32 i64 Now we cast the last two i64s to the right type. Fixes the crash in PR14668. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173615 91177308-0d34-0410-b5e6-96231b3b80d8

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

2013-01-25In 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
