2013-02-05Fix remaining StringRef abuse.Tim Northover
This should fix the valgrind buildbot failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174375 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-05Fix formatting in AArch64 backend.Tim Northover
This should fix three purely whitespace issues: + 80 column violations. + Tab characters. + TableGen brace placement. No functional changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174370 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-05Remove cyclic dependency in AArch64 librariesTim Northover
This moves the bit twiddling and string fiddling functions required by other parts of the backend into a separate library. Previously they resided in AArch64Desc, which created a circular dependency between various components. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174369 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04Disable a couple more vector splat optimizations on PPC.Benjamin Kramer
I didn't see those because the test case used "not grep". FileCheck the test and XFAIL it, preserving the old optimization, so this can be fixed eventually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174330 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04SelectionDAG: Teach FoldConstantArithmetic how to deal with vectors.Benjamin Kramer
This required disabling a PowerPC optimization that did the following: input: x = BUILD_VECTOR <i32 16, i32 16, i32 16, i32 16> lowered to: tmp = BUILD_VECTOR <i32 8, i32 8, i32 8, i32 8> x = ADD tmp, tmp The add now gets folded immediately and we're back at the BUILD_VECTOR we started from. I don't see a way to fix this currently so I left it disabled for now. Fix some trivially foldable X86 tests too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174325 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
2013-02-04ARM cost model: Penalize insertelement into D subregistersArnold Schwaighofer
Swift has a renaming dependency if we load into D subregisters. We don't have a way of distinguishing between insertelement operations of values from loads and other values. Therefore, we are pessimistic for now (The performance problem showed up in example 14 of gcc-loops). radar://13096933 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174300 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01Two changes relevant to LEA and x32:David Sehr
1) allows the use of RIP-relative addressing in 32-bit LEA instructions under x86-64 (ILP32 and LP64) 2) separates the size of address registers in 64-bit LEA instructions from control by ILP32/LP64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174208 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31Switch the code added in r173885 to use the new, shiny RTTIChandler Carruth
infrastructure on MCStreamer to test for whether there is an MCELFStreamer object available. This is just a cleanup on the AsmPrinter side of things, moving ad-hoc tests of random APIs to a direct type query. But the AsmParser completely broken. There were no tests, it just blindly cast its streamer to an MCELFStreamer and started manipulating it. I don't have a test case -- this actually failed on LLVM's own regression test suite. Unfortunately the failure only appears when the stars, compilers, and runtime align to misbehave when we read a pointer to a formatted_raw_ostream as-if it were an MCAssembler. =/ UBSan would catch this immediately. Many thanks to Matt for doing about 80% of the debugging work here in GDB, Jim for helping to explain how exactly to fix this, and others for putting up with the hair pulling that ensued during debugging it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174118 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-31Give the MCStreamer class hierarchy LLVM RTTI facilities for use withChandler Carruth
isa<> and dyn_cast<>. In several places, code is already hacking around the absence of this, and there seem to be several interfaces that might be lifted and/or devirtualized using this. This change was based on a discussion with Jim Grosbach about how best to handle testing for specific MCStreamer subclasses. He said that this was the correct end state, and everything else was too hacky so I decided to just make it so. No functionality should be changed here, this is just threading the kind through all the constructors and setting up the classof overloads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174113 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31Add AArch64 as an experimental target.Tim Northover
This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174054 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30This patch reworks how llvm targets set Jack Carter
and update ELF header e_flags. Currently gathering information such as symbol, section and data is done by collecting it in an MCAssembler object. From MCAssembler and MCAsmLayout objects ELFObjectWriter::WriteObject() forms and streams out the ELF object file. This patch just adds a few members to the MCAssember class to store and access the e_flag settings. It allows for runtime additions to the e_flag by assembler directives. The standalone assembler can get to MCAssembler from getParser().getStreamer().getAssembler(). This patch is the generic infrastructure and will be followed by patches for ARM and Mips for their target specific use.
