Yest. thanks. I just resolved this error by installing MPFR, MPC and GMP(by the way, these are not listed as prerequisites in the website.). But other errors come: /home/xxx/llvm/tools/dragonegg/src/TypeConversion.cpp: In function > ‘llvm::FunctionType* ConvertArgListToFnType(tree_node*, > llvm::ArrayRef<tree_node*>, tree_node*, bool, llvm::CallingConv::ID&, >

Looks like recent changes to Attributes.h broke the dragonegg build.

Yup, this is EXACTLY what is going on. I took this very simple C function: int Array[1000]; void test(int

I am new to LLVM, and I'm trying to compile llvm and llvm-gcc from subversion on a Solaris10/SPARC machine. I have already tried building llvm-2.4 on this machine, but it failed. I then tried the subversion sources (rev. # 65253 fro llvm and rev#65263 for llvm-gcc) and llvm at least builds correctly ( I however have not tried testing it!). I can execute binaries located in

Hi all, This patch is to fix a problem on PPC64 where an unaligned memcpy is generated. The testcase is this: $ cat testcase.c void Qux() { char Bar[11] = {0}; } What happens is that we produce LLVM code like this: call void @llvm.memcpy.i64( i8* %event_list2, i8* getelementptr ([11 x i8]* @C.103.30698, i32 0, i32 0), i64 11, i32 8 ) Notice that it has an 8-byte alignment. However, the Bar

Duncan, Is the documentation for using Polly support in dragonegg correct? I built llvm/polly/dragonegg using the documentation at http://polly.llvm.org/example_load_Polly_into_dragonegg.html with... GCC=/sw/lib/gcc4.7/bin/gcc-4 LLVM_CONFIG=/sw/opt/llvm-3.2/bin/llvm-config ENABLE_LLVM_PLUGINS=1 make CPPFLAGS="-DENABLE_LTO -I/sw/include" The resulting dragonegg plugin works fine

Hi, I was trying to do a source to source transformation in llvm from c++11 more basic c++ (to transform away auto etc.) using llvm3.1. I generate llvm bitcode using "clang++ -emit-llvm ...", but executing llc -march=cpp throws /home/broes/software/llvm/lib/Target/CppBackend/CPPBackend.cpp:493: void {anonymous}::CppWriter::printAttributes(const llvm::AttrListPtr&, const

Hi: I'm trying to reproduce an arbitrary precision constant from 'Why and How to Use Arbitrary Precision' (Ghazi et al., COMPUTING IN SCIENCE & ENGINEERING May/June 2010; http://perso.ens-lyon.fr/philippe.theveny/cise.pdf): d = 173746a + 94228b ? 78487c where: a = sin(1022), b = log(17.1), and c = exp(0.42).

Hi, I am trying to write code in C for an R package. I need high precision in the form of the mpfr and gmp packages. I have installed mpfr and gmp under the instructions of the following website http://pauillac.inria.fr/cdrom_a_graver/prog/pc/mpfr/eng.htm and I get no errors. I have put the header files (mpfr.h and gmp.h) in the folder C:\Program Files\R\R-2.13.0\include; allowing my c code to

Hi, We want to apply the deepest possible inlining to the target code. Looks like builder.Inliner = createFunctionInliningPass(2000); does the sufficient inlining, but what would be the best value for threshold here? Apparently, builder.Inliner = createFunctionInliningPass(numeric_limits<int>::max()); gives less inlining, that 2000. Thanks, - D.
