*added file for test cases for i386 intel syntax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174900 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-06This is a follow-up on r174446, now taking Atom processors intoEli Bendersky
account. Atoms use LEA for updating SP in prologs/epilogs, and the exact LEA opcode depends on the data model. Also reapplying the test case which was added and then reverted (because of Atom failures), this time specifying explicitly the CPU in addition to the triple. The test case now checks all variations (data mode, cpu Atom vs. Core). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174542 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-05Make sure the correct opcodes are used to SUB and ADD the stackEli Bendersky
pointer in function prologs/epilogs. The opcodes should depend on the data model (LP64 vs. ILP32) rather than the architecture bit-ness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174446 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04More MSan/ASan annotations.Evgeniy Stepanov
This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains fixes for 2 issues: - X86JIT reads return address from stack, which MSan does not know is initialized. - bugpoint tests run binaries with RLIMIT_AS. This does not work with certain Sanitizers. We are no longer including config.h in Compiler.h with this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174306 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-29Teach SDISel to combine fsin / fcos into a fsincos node if the followingEvan Cheng
conditions are met: 1. They share the same operand and are in the same BB. 2. Both outputs are used. 3. The target has a native instruction that maps to ISD::FSINCOS node or the target provides a sincos library call. Implemented the generic optimization in sdisel and enabled it for Mac OSX. Also added an additional optimization for x86_64 Mac OSX by using an alternative entry point __sincos_stret which returns the two results in xmm0 / xmm1. rdar://13087969 PR13204 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173755 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

2013-01-20Revert 172708.Nadav Rotem
The optimization handles esoteric cases but adds a lot of complexity both to the X86 backend and to other backends. This optimization disables an important canonicalization of chains of SEXT nodes and makes SEXT and ZEXT asymmetrical. Disabling the canonicalization of consecutive SEXT nodes into a single node disables other DAG optimizations that assume that there is only one SEXT node. The AVX mask optimizations is one example. Additionally this optimization does not update the cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172968 91177308-0d34-0410-b5e6-96231b3b80d8
