similar to: [LLVMdev] Linking static external library into an LLVM pass library?

Hi all, I have a new sample project set up in my llvm/projects directory, and I'd eventually like my frontend to generate an LLVM IR tree. To do so, I believe I need to link to the appropriate LLVM libraries. That's where I'm stuck. I can't seem to find any specific documentation that describes how to set up a new project to link to LLVM libraries. To get started, I added a

Hi all! I didn't manage to link my regalloc to lli (I added USEDLIBS to its makefile). Without it I can't run tests cause they need lli to be built. So how can I link createMyRegisterAllocator function to lli? Thanks.

And this brings back CommandLine Error: Arugment blah defined more than once!

I did so from the first time and I also needed to add my library .a file to the USEDLIBS variable within llc makefile to build llc. I wonder how lli links with all the rest LLVM as it seems to include no lib within its makefile. May be I need to

HI Duncan, Your understanding of the problem is correct. However, the XYZ class is not inside an anonymous name space. Also, all the XYZ methods are defined in the .cpp file. Looking at the error message: opt: symbol lookup error: path/to/pass.so: undefined symbol: _ZN12DataTransferD1Ev Where DataTransfer is the class name. Maybe I am missing certain type of constructors? Thanks, Welson On

Originally, the problem is the lack of .cpp file. Then I noticed the compilation log is not showing the .o file being generated for the non-pass classes. Then I added the .cpp files for each .h file, then the .o files are being generated, shown in the Debug directory. Actually, if I add "VERBOSE = 1" in the Makefile, it shows the linking command is actually linking all the .o files into

Hi Welson, are you saying that the .o file containing the class is being linked into the .so file, but nonetheless you get "undefined symbol XYZ" errors where XYZ is that class? Maybe you defined the class inside an anonymous name space? Alternatively, if XYZ refers to a method of the class, maybe you forgot to define that method. Ciao, Duncan.

I forgot that lli was "special". It uses the "JIT" keywoard which means "figure out the right libraries to use for a JIT compiler and runtime". So, just add this, to tools/lli/Makefile: USEDLIBS := LLVMBCWriter That worked for me. Reid. On Thu, 2005-02-24 at 16:58, Patrick Meredith wrote: > Where do I add that line?

I managed to link my RegAlloc.a library to llc tool but can;t make the same with lli tool. Should I use USEDLIBS variable in lli makefile (like llc) or there is another way?

May be I need to include/link my lib somewhere else? Ah, that's probably it. Try

My pass uses another class which is defined in a separate .h file, which sits in the same folder as the pass .cpp file. The pass compiles fine, but when using the pass "opt -load ...", there is an error: opt symbol lookup error .... undefined symbol xxx, where xxx is the class name. It looks like that class file's object file is not linked into the pass.so file. How should I change

Hi Thanks for all your feedback. I just found the reason for the compile failure for my analysis pass: I had to add my object to the namespace llvm instead of anonymous. This took me some time since i was looking for an linking failure... but as errors go i should have looked at the error message a little closer. So for all those trying to add an analysis path: * add the object name to the

Hey Duncan, Thanks! I figured out this piece of code finally: Value *gep = call->getArgOperand(0); if ( ConstantExpr *pCE = dyn_cast<ConstantExpr>(gep) ) { Value *firstop = pCE->getOperand(0); if (GlobalVariable *GV = dyn_cast<GlobalVariable>(firstop)){ Constant *v = GV->getInitializer(); if

Thanks Duncan, Yes, it is a ConstantExpr! Thank you!

Hi Welson, the default alias analysis is -no-aa. As the name suggests it just returns MayAlias for everything. Maybe you are using that one? Best wishes, Duncan.

Yeah. Is there a way to specify noalias between these arguments?
