Hi, how can i correctly calculate the size of a member of a struct (including alignment etc)? This doesn't work : const StructType *STy = cast<StructType>(Ty); for (StructType::element_iterator I = STy->element_begin(), E = STy->element_end(); I != E; ++I) { usigned size =I->get()->getScalarSizeInBits(); //often

I've been continuing plugging gaps as I find them, which might not be the best way to solve this problem, but it has produced something that seems to do roughly what I expect. I've split it into

Hello, I noticed a bit of a gap in the current code for unions: a ConstantUnion cannot be written out to .ll. Hopefully I'm not stepping on Talin's toes by posting this, it's a fairly straightforward adaptation of the code for structs just above.

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

Hello, Can I define a named type ? %rt = {%rt} llvm-as can parse this definition without errors. JIT executes '%0 = alloca %rt' as allocating a memory with size 0. Because the llvm::TargetData::getTypeAllocSize accually returns 0 in this case. The function that calculates %rt's size is by the TargetData::getStructLayout, which calculates the a layout of %rt. It can only returns 0

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()));

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

I'm running into lots of problems with this call back. Mostly the problem occurs because this callback is used before types are legalized. However, the code generator does not have a 1-1 correspondence between all LLVM types and the codegen types. This leads to problems when getSetCCResultType is passed in an invalid type, but has a valid LLVM type attached to it. An example is <3 x

Hi, the smbldap tools are a great thing to have, thanks a lot! I just wonder if it would be possible to set a password via the command line, like: smbldap-passwd.pl testuser1 not24get I have to create accounts for several hundreds people every year and give them an immutable password. So long I do that with smbpasswd, ldappasswd and a tiny script around these tools. I tried smbldap-passwd.pl

Hi list I'm running a Samba PDC on Ubuntu Lucid (3.4.7) and am unable to join Windows 7 machines to the domain. I have applied the registry changes described at http://wiki.samba.org/index.php/Windows7 Windows XP machines can join with no problems.

I've been using rsync under Win2k(cygwin) for some time without error. But after a recent upgrade of cygwin I've started to get errors, and rsync no longer works. I'm not sure if this is a rsync problem, ssh problem, or cygwin problem, so I figured I'd try here first (since ssh seems to work fine). On my windows machine: > rsync --version rsync version 2.5.6 protocol

With local com ports I can use stty to inspect the port settings. Is there a similiar method with a socket connection? I have an odd situation happening where my data collection program that is working on 3 machines is not working on the 4th. The program opens a socket to remote RS232 device no data is recieved. strangely though if I "telnet IP port" to the device it will send the

Hi Micah, I think that getSetCCResultType should only be called for legal types. Disabling it on isPow2VectorType is not the way to go because there are other illegal vector types which are pow-of-two. I suggest that you call it only after type-legalization. BTW, you can't set the LLVMTy yourself because you don't have access to the LLVMContext at that point. Nadav From:
