* Support: ensure proper state in ErrorOr copy ctors before calling 'get'Meador Inge2013-02-051-7/+4
| | | | | | | | | | | Some paths through the copy constructors for 'ErrorOr' were calling 'get' when 'HasError' and 'IsValid' were not properly initialized. Depending on what happened to be in memory for those member variables the asserts in 'get' might incorrectly fire. Fixed by ensuring that the member variables in question are always initialized before calling 'get'. llvm-svn: 174381

* Loop Vectorizer: Handle pointer stores/loads in getWidestType()Arnold Schwaighofer2013-02-052-9/+180
| | | | | | | | | | | | | | | | | In the loop vectorizer cost model, we used to ignore stores/loads of a pointer type when computing the widest type within a loop. This meant that if we had only stores/loads of pointers in a loop we would return a widest type of 8bits (instead of 32 or 64 bit) and therefore a vector factor that was too big. Now, if we see a consecutive store/load of pointers we use the size of a pointer (from data layout). This problem occured in SingleSource/Benchmarks/Shootout-C++/hash.cpp (reduced test case is the first test in vector_ptr_load_store.ll). radar://13139343 llvm-svn: 174377

| | | | | | | | The sh_link in the ELF section header of .ARM.exidx should be filled with the section index of the corresponding text section. llvm-svn: 174372
* ARM cost model: Cost for scalar integer casts and floating point conversionsArnold Schwaighofer2013-02-052-7/+266
| | | | | | Also adds some costs for vector integer float conversions. llvm-svn: 174371
* Fix formatting in AArch64 backend.Tim Northover2013-02-0524-841/+577
| | | | | | | | | | | This should fix three purely whitespace issues: + 80 column violations. + Tab characters. + TableGen brace placement. No functional changes. llvm-svn: 174370
* Remove cyclic dependency in AArch64 librariesTim Northover2013-02-0523-814/+874
| | | | | | | | 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. llvm-svn: 174369

* When the target-independent DAGCombiner inferred a higher alignment for a load,Owen Anderson2013-02-053-6/+10
| | | | | | | | | | | it would replace the load with one with the higher alignment. However, it did not place the new load in the worklist, which prevented later DAG combines in the same phase (for example, target-specific combines) from ever seeing it. This patch corrects that oversight, and updates some tests whose output changed due to slightly different DAGCombine outputs. llvm-svn: 174343

* [Stack Alignment] emit warning instead of a hard errorManman Ren2013-02-042-5/+5
| | | | | | | | | | | Per discussion in rdar://13127907, we should emit a hard error only if people write code where the requested alignment is larger than achievable and assumes the low bits are zeros. A warning should be good enough when we are not sure if the source code assumes the low bits are zeros. rdar://13127907 llvm-svn: 174336
* Initial cleanups of the param-attribute code in the bitcode reader/writer.Bill Wendling2013-02-045-66/+59
| | | | | | | | | Rename the PARAMATTR_CODE_ENTRY to PARAMATTR_CODE_ENTRY_OLD. It will be replaced by another encoding. Keep around the current LLVM attribute encoder/decoder code, but move it to the bitcode directories so that no one's tempted to use them. llvm-svn: 174335

* SelectionDAG: Teach FoldConstantArithmetic how to deal with vectors.Benjamin Kramer2013-02-047-55/+129
| | | | | | | | | | | | | | | | | 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. llvm-svn: 174325

* Pass CPPFLAGS/CFLAGS/CXXFLAGS from the environment of configure toPatrik Hagglund2013-02-044-5/+29
| | | | | | | | | | | | | | | | | Makefile.config. This is implied at the bottom of the help text of configure (besides CC/CXX/LDFLAGS, already passed to Makefile.config). For backward compatibility, the values of CFLAGS and CXXFLAGS defaults to empty, overriding the default values provided by autoconf (for example, '-g -O2' when CC=gcc'). $(CPP) is not used by our makefiles. Therefore, the value of CPP is not passed to Makefile.config, despite beeing mentioned by 'configure --help'. llvm-svn: 174313
* More MSan/ASan annotations.Evgeniy Stepanov2013-02-046-9/+24
| | | | | | | | | | | | | | 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. llvm-svn: 174306

* ARM cost model: Penalize insertelement into D subregistersArnold Schwaighofer2013-02-043-0/+65
| | | | | | | | | | | 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 llvm-svn: 174300
* Turn off uninitialized-use warnings for gcc in cmake buildEdwin Vane2013-02-042-0/+24
| | | | | | | | | | | | Added support to the cmake build to turn off uninitialized use warnings for gcc. This cleans the build up somewhat. Used logic simpler than found in autoconf by making use of the fact that although gcc won't complain about unsupported -Wno-* flags it *will* complain about unsupported -W flags.

* Added instance variable/initializers/getter/setters for new keyword ↵Michael Gottesman2013-02-032-13/+30
| | | | | | | | | | | | | | externally initialized to GlobalVariable. No *TRUE* functionality change. I am going to add in the actual test cases with the actual functionality changes in a later patch because I want to include some test cases. To be clear when I say no *TRUE* functionality change I mean that this patch (like it says in the title) only contains getters/setters and sets up a default initial value of the instance variable to false so that this patch does not affect any other uses of Global Variable.h. llvm-svn: 174295
