An enumeration for the kinds of linkage for global values. Hi, I'm currently writing a compiler that takes llvm-ir input. I'm a little confused by the following linkage flags: Enumerator: > > ExternalLinkage: Externally visible function > > AvailableExternallyLinkage: Available for inspection, not emission. > > LinkOnceAnyLinkage: Keep one copy of function when linking (inline) > > LinkOnceODRLinkage: Same, but only replaced by something equivalent. > > WeakAnyLinkage: Keep one...

Hi, I tried this as well, using the following line to add function declaration to the caller module. Function::Create(FT, Function::ExternalLinkage, "gcd", mod); Where "FT" is the same as before. And the output produced by the PrintModulePass becomes: ; ModuleID = 'GCDMain' declare i32 @gcd(i32, i32) define i32 @main() { EntryBlock: %tmp = call i32 @gcd(i32 30, i32 50) ret i32 %tmp } But it still fails...

Hi, I am working on the COFF backend and am wondering where llvm.memcpy gets lowered to memcpy ? It seems to be done by the assembler backends and would have thought it would either be done by a lowering pass or done by the mangler but it does not seem to be either. Many thanks in advance, Aaron -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Good day. I am facing issue with creating a GlobalVariable. I already have an extern for that global in a header file to use it in the following way extern const void* DATA_TABLE[]; And with a LLVM PASS, I am trying to create this array with the same name and with initializer. So, I have following: GlobalVariable *gvar_data = new GlobalVariable( M, blockItems->getType(), true,

...re out or find in the documentation: I'm doing something like this to call "sin" from std: std::vector<const Type*> params; params.push_back( Type::FloatTy ); FunctionType *FT = FunctionType::get( Type::FloatTy, params, false); Function *F = new Function( FT, Function::ExternalLinkage, "sin", M ); CallInst *CallExternal = new CallInst( F, SomeValue, "external_call", BB ); I can make some calls to functions like glclear() as I'm using opengl: ... Function *F = new Function( FT, Function::ExternalLinkage, "glclear", M ); ... But if I want...

I have changed it to ExternalLinkage. Now, in LLVM IR, it looks like that: @DATA_TABLE = external global [0 x i8*], section "data_section", align 16 #0 @DATA_TABLE.1 = global [10 x i8*] [i8* inttoptr (i64 53415718 to i8*), i8* bitcast (void (%class.Hello*)* @_ZN5Hello5ptofnEv to i8*),...], section "data_section",...
