similar to: [LLVMdev] FunctionType as a function argument

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

Hi Salomon, please don't forget to reply to the list too (I've CC'd the list). > I don't think my code is doing anything worng... No, it looks fine to me, and the interpreter certainly supports this. That suggests that the value of %str is not being transmitted to the function right. If it is getting the wrong pointer value, that would explain why it barfs. Ciao, Duncan.

Hi everyone ! I am very new to LLVM and intent to use it in a research project. I have a problem with the interpreter: I have a simple compiler that generates LLVM bitcode, JIT it and execute it, and it works very well. Now I would like to execute it using the interpreter. And I get a segfault. Here is the code : // This code JIT the function and executes it llvm::InitializeNativeTarget();

In my case, I am working on a posix regular expression library that uses LLVM to execute a regular expression. Each regular expression is a very small sets of code and is faster to interpret than to JIT then execute. I wanted to JIT only when the regular expression is executed more than 20 times. The benchmarks I have run show that my library is amzingly fast to execute a regular expression

Hi! In Line 230 of llvm\Support\TypeBuilder.h is support for void*: /// void* is disallowed in LLVM types, but it occurs often enough in C code that /// we special case it. template<> class TypeBuilder<void*, false> : public TypeBuilder<types::i<8>*, false> {}; If would be cool if the same thing can be added for const void*: template<> class

I'm encountering a few problems in my migration that I haven't yet figured out. `getOrInsertFunction` is generating a SEGFAULT at FunctionType::isValidArgumentType(llvm::Type*).  I'm calling it as:     generic_ptr_ = llvm::PointerType::get( llvm::Type::getInt8Ty(context), 0 );     f_natural_int = llvm::IntegerType::get(context, 64);     module->getOrInsertFunction(

For my introductory Compiler Construction class, I have been giving the students a project to write a simple compiler for a toy, single- inheritance object-oriented language. We give them a set of classes implementing an AST for the language and a type checker as well. The students write (1) a scanner and parser to build the AST; (2) a translator from AST to LLVM; and (3) a couple of

Hello, Anyone else experiencing problems with the latest spandsp (pre3) and last libtiff beta? I'm getting 8 bytes long file, with the TIFF header only during such connection: -- Accepting call from 'XXXXXXX' to 'YYYYYY' on channel 0/2, span 1 -- Executing SetVar("Zap/2-1", "FAXFILE=/tmp/foch.tif") in new stack -- Executing

Hi, I'm having a play with LLVM to implement a custom language (for my intellectual curiosity only). I'm wondering how, when using IRBuilder, one can can it to emit a recursive type definition? The code for TypeBuilder explicitly states that it doesn't handle recursive types... I'm after being able to emit, programmatically, stuff like the Named Types example in the Language

That and the possibility of differently sized pointers made me hesitate to dive into implementing this. I guess nailing it down to be the platform equivalent of size_t would be sensible here.

Hi all, I have setup samba / openldap as describes by the idealx howto and as such I am using the smbldap-tools. However, I would like to add the givenname and email address fields for all users. What is the best way to do this? I would prefer continuing to use the smbldap-tools, but I cannot seem to find a good way to do this. When I try to: $ smbldap-usermod -M testuser@testdomain.net

I looked through the "intp" thread. I don't really want to start that argument up again, but my immediate thought would be to create a new class of "picked-by-the-target" integer types (equivelents of size_t, intptr_t, etc...), and two new instructions, zcast and scast, which are only valid in the context of casting to / from integer types of unknown sizes. To begin with,

Hi Everyone, I am trying to construct the print statement : printf("value:%d\n", value); This is my llvm code. It is seg faulting at builder.CreateGlobalStringPtr(str,""). Thanks.
