2013-05-06Fix formatting. Patch by o11c.Duncan Sands
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181189 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-06Fix const merging when an alias of a const is llvm.used.Rafael Espindola
We used to disable constant merging not only if a constant is llvm.used, but also if an alias of a constant is llvm.used. This change fixes that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181175 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-05Add EH support to the MCJIT.Rafael Espindola
This gets exception handling working on ELF and Macho (x86-64 at least). Other than the EH frame registration, this patch also implements support for GOT relocations which are used to locate the personality function on MachO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181167 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-05For ARM backend, fixed "byval" attribute support.Stepan Dyatkovskiy
Now even the small structures could be passed within byval (small enough to be stored in GPRs). In regression tests next function prototypes are checked: PR15293: %artz = type { i32 } define void @foo(%artz* byval %s) define void @foo2(%artz* byval %s, i32 %p, %artz* byval %s2) foo: "s" stored in R0 foo2: "s" stored in R0, "s2" stored in R2. Next AAPCS rules are checked: 5.5 Parameters Passing, C.4 and C.5, "ParamSize" is parameter size in 32bit words: -- NSAA != 0, NCRN < R4 and NCRN+ParamSize > R4. Parameter should be sent to the stack; NCRN := R4. -- NSAA != 0, and NCRN < R4, NCRN+ParamSize < R4. Parameter stored in GPRs; NCRN += ParamSize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181148 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-05PatternMatch: Fix documentation - 'function' not 'attribute'Arnold Schwaighofer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181146 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-05PatternMatch: Matcher for (un)ordered floating point min/maxArnold Schwaighofer
Add support for matching 'ordered' and 'unordered' floating point min/max constructs. In LLVM we can express min/max functions as a combination of compare and select. We have support for matching such constructs for integers but not for floating point. In floating point math there is no total order because of the presence of 'NaN'. Therefore, we have to be careful to preserve the original fcmp semantics when interpreting floating point compare select combinations as a minimum or maximum function. The resulting 'ordered/unordered' floating point maximum function has to select the same value as the select/fcmp combination it is based on. ordered_max(x,y) = max(x,y) iff x and y are not NaN, y otherwise unordered_max(x,y) = max(x,y) iff x and y are not NaN, x otherwise ordered_min(x,y) = min(x,y) iff x and y are not NaN, y otherwise unordered_min(x,y) = min(x,y) iff x and y are not NaN, x otherwise This matches the behavior of the underlying select(fcmp(olt/ult/.., L, R), L, R) construct. Any code using this predicate has to preserve this semantics. A follow-up patch will use this to implement floating point min/max reductions in the vectorizer. radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181143 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-04Allow host triple to be correctly overridden in CMake buildsTim Northover
The intended semantics mirror autoconf, where the user is able to specify a host triple, but if it's left to the build system then "config.guess" is invoked for the default. This also renames the LLVM_HOSTTRIPLE define to LLVM_HOST_TRIPLE to fit in with the style of the surrounding defines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181112 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-04Fix a performance bug in the Linker.Rafael Espindola
Now that we hava a convinient place to keep it, remeber the set of identified structs as we merge modules. This speeds up the linking of all the bitcode files in clang with the gold plugin and -plugin-opt=emit-llvm (i.e., link only, no codegen) from 5:25 minutes to 13.6 seconds!

2013-05-03Add support for reading ARM ELF build attributes.Amara Emerson
Build attribute sections can now be read if they exist via ELFObjectFile, and the llvm-readobj tool has been extended with an option to dump this information if requested. Regression tests are also included which exercise these features. Also update the docs with a fixed ARM ABI link and a new link to the Addenda which provides the build attributes specification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181009 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-01This exposes more MCJIT options via the C API:Filip Pizlo
CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like. Previously it was only possible to create an MCJIT that used CodeModel::JITDefault. EnableFastISel: It's now possible to turn on the fast instruction selector. The CodeModel option required some trickery. The problem is that previously, we were ensuring future binary compatibility in the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the bindings then bzero the remaining bits. This works great but assumes that the bitwise zero equivalent of any field is a sensible default value. But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model. In both of those, the default for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero. Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp illustrates the change, as does the comment in ExecutionEngine.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180893 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-01This patch breaks up Wrap.h so that it does not have to include all of Filip Pizlo
the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8
