In trying to write a C binding for DIBuilder of llvm 3.6.1, I can't see a way to unwrap llvm::DITypeRef, declared in include/llvm/IR/DebugInfo.h. This is a class with one data member, a pointer to Metadata. If I try to make my C type a struct with one pointer, I can't cast it to DITypeRef. If I try to go inside the classes and use the pointer, I can cast, but can't construct a

Have I correctly inferred below, how I build IR and debug info for a function type and a function (value), in particular, how to supply the names of the formal parameters? To create a function in llvm IR and give names to its formal parameters, I must: 1. Build a LLVMTypeRef for the type of each formal and the function result. 2. Build a function type using LLVMFunctionType, from the results of

I am, from a front end, calling functions like LLVMModuleCreateWithName, found in Core.h, ultimately calling LLVMWriteBitcodeToFile, found in BitWriter.h. Do I correctly presume, from the existence of LLVMDisposeModule, that I am responsible for calling it when I'm done? Will I need to do deeper disposing myself? I presume at least I will need to free strings I allocated myself, such as the

For this C code: typedef struct s2 { char s2C1 , s2C2; } s2td; clang generates: %struct.s2 = type { i8, i8 } which I lets llvm decide on the actual layout of this type. For the return statement in: struct s2 fs2 ( char fs2p1 ) { struct s2 ls2; ls2.s2C1 = 'B'; ls2.s2C2 = fs2p1; return ls2; } I see this IR: %struct.s2 =

The language I am working on connecting to an llvm back-end (Modula-3) allows a fairly extensive set of recursive declarations. It looks like I can translate all its high-level types using four llvm types that refer to another type: function, struct, pointer, and array. It looks like I can alter an llvm struct type in place after it has been created, using StructType::setBody. I don't see a

I can build llvm 3.4.2 fine, using instructions in GettingStarted.html, and making assumptions to account for my using tar files instead of svn. Although I had downloaded and extracted both llvm-3.4.2.src.tar.gz and cfe-3.4.2.src.tar.gz, giving directories llvm-3.4.2.src and cfe-3.4.2.src, clang apparently did not get built. The only files with names starting with "clang" anywhere

This is partly an llvm question, and maybe partly C++. I am trying to make calls on code in the llvm infrastructure.(3.4.2) I appear to be missing some include files, but don't know how to track them down. I get compile errors on existing llvm header files, like the following two examples: -------------------------------------------------------------------------------- In file included

Hello. I was trying to compile https://github.com/llvm/llvm-project/tree/master/libunwind using: - MSVC - Clang I wasn't able to configure this project for using MSVC (directly or via clang-cl): >cmake -G Ninja -DLLVM_PATH="C:/Users/clang/llvm-project-10.0.1/llvm" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="C:\Users\clang\libunwind_llvm" ../libunwind --

Greetings all, Ran into a strange problem with the krige function from geoR. The problem that I am having is that while the krige function seems to work well, the resulting predicted values are all NAs. Given the size of the datasets I am working with can't attach it, but I can provide snippets of the datasets. > casedata station year month day obs mpe bias type

It will be interesting to see how many standards get broken, and how many proprietary hooks get thrown into the pot.

Hi R-help, I am working with US COOP network station data and the files are concatenated in single rows for all years, but I need to pull these apart into rows for each day. To do this, I need to extract part of each row such as station id, year, mo, and repeat this against other variables in the row (days). My problem is that there are repeated values for each day, and the files are fixed width
