similar to: [LLVMdev] Is the head of llvm-gcc not working with the head of llvm for anyone else?

Since yesterday I've been getting the error below when building llvm-gcc on Ubuntu Hardy on x86. For some reason, several instances of autoconf are getting confused and failing to detect a stdlib.h.

Anyone else seeing this?

I was running into a problem with compiling llvm with gcc 4.4 on fedora 11 with --enable-optimized. I was seeing this warning dozens of times: /net/hakodate/scratch/llvm/llvm/include/llvm/CodeGen/ValueTypes.h: In member function ‘llvm::SDNode*<unnamed>::SPUDAGToDAGISel::Select(llvm::SDValue)’: /net/hakodate/scratch/llvm/llvm/include/llvm/CodeGen/ValueTypes.h:362: warning: comparison always

My experimental code calls DAG.getNode to construct a unary node with a flag result. Unfortunately the argument turns out to be constant, so lib/CodeGen/SelectionDAG/SelectionDAG.cpp:2332 calls VT.getSizeInBits on the flag type, which isSimple(), so we call V.getSizeInBits at ValueTypes.h:560 and fail at ValueTypes.h:240: clang: .../include/llvm/CodeGen/ValueTypes.h:240: unsigned int

I'm away from my Linux machines, if this hasn't been resolved by tonight I'll send more details. THe problem in cplus-dem.c is that CPP is conditionally including code that comes when HAVE_STDLIB is not defined, including an alternate protptype for malloc() that conflicts with the existing one. This is just what causes the error I sent-- no idea what the root cause is. Thanks,

Hello, Since 2.5 is near, I have been trying to build llvm and llvm-gcc for MingW, but hit several problem (using the current trunk). First issue is that unittests don't build for MingW, the attached patch should fix it. Second issue is that llvm-gcc fails for me with the following error: /c/cygwin/home/jlerouge/buildbot/llvm-test/gcc-build/./gcc/xgcc

I am trying to build the llvm-gcc frontend. I think I have followed the directions correctly. I am using cygwin on XP SP2 (uname -a reports: CYGWIN_NT-5.1 pad7 1.5.25(0.156/4/2) 2007-12-14 19:21 i686 Cygwin) gcc --version reports: gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) Since there is no binary for llvm-gcc I am following the directions in the tar file for the 4.2 version. -

The LegalizeDAG.cpp file has this code in SelectionDAGLegalize::PromoteNode: case ISD::BSWAP: { unsigned DiffBits = NVT.getSizeInBits() - OVT.getSizeInBits(); Tmp1 = DAG.getNode(ISD::ZERO_EXTEND, dl, NVT, Tmp1); Tmp1 = DAG.getNode(ISD::BSWAP, dl, NVT, Tmp1); Tmp1 = DAG.getNode(ISD::SRL, dl, NVT, Tmp1, DAG.getConstant(DiffBits, TLI.getShiftAmountTy()));

The llvm-gcc front end mingw binary on llvm.org has patched a lot of *.h files under include directory. But when building llvm-gcc on mingw myself, there is no header file generated under include directory. So where do these header files come from? I am concerned for their licenses.

Thank you, I did try that and got the following error: checking for library containing strerror... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES. make[1]: *** [configure-target-libiberty] Error 1 make[1]: Leaving directory `/home/ghoang/llvm-test/llvm-gcc-2.8-build' make: *** [all] Error 2 I also tried adding --disable-libiberty but make would fail even earlier

Hello LLVM, In DAGCombiner.cpp, MergeConsecutiveStores uses int64_t ElementSizeBytes = MemVT.getSizeInBits()/8; https://github.com/llvm-mirror/llvm/blob/master/lib/CodeGen/SelectionDAG/DAGCombiner.cpp#L10669 which is broken for i1 types where getSizeInBits() == 1. My out-of-tree target hits this case and eventually LLVM asserts in Type.cpp. Is there some reason MergeConsecutiveStores should

So, I'm trying to build everything from source for the Debian package for LLVM, including the C/C++ front end. I'm running this build on LLVM 1.4 source (the released tarball), using Debian unstable (gcc 3.3.5, on a 2.6.8 kernel, on an x86_64 box, dual CPU). Before I get _too_ deep into it, I thought I would ask if the following compilation failure on the CFE looks the least bit familiar
