similar to: [LLVMdev] A few more questions about DIFactory and source-level debugging.

After to speaking to Devang and a number of other people at the developer's conference, I was able to make some forward progress on getting debugging to work. I'm now able to actually single-step through my program and set breakpoints, and examine function parameters. However, I'm also seeing a lot of new problems which weren't exposed before. After spending the better part of two

Problem 1: I tried llvm-db of LLVM 1.6, in the Linux environment. However, it always prompts the following info for different tests: ====================================== :> llvm-db a.out.bc llvm-db: The LLVM source-level debugger Loading program... successfully loaded 'a.out.bc'! (llvm-db) run Starting program: a.out.bc Error: Error waiting for the child process to stop. It exited

I'm playing around with different combinations of LTO passes, and I've run into a strange problem: I have a 'main' function that looks like this: define i32 @"main(tart.core.Array[tart.core.String])->int"(%"tart.core.Array[tart.core.String]"* %args) { entry: call void @llvm.dbg.func.start(metadata !0) call void @llvm.dbg.stoppoint(i32 2, i32 19, metadata

Well, after some investigation I have a few more clues as to what is going on. I have a module which contains a call to an external native function. This native function lives in a static library, and there is an external declaration for it in the module. I find that I can run "llvm-ld -disable-opts -native -l mylibrary test.bc" and it works fine. That is, llvm-ld is able to

Sounds like LLVM thinks the calling conventions or declarations are mismatched.

Dear Staff, I am asking this question: given a line of IR code in *.ll file, how can I know the corresponding line number and C/C++ source file name for this IR code? I am investigating some code patterns with LLVM IR, I need to know where this IR code come from (the line number in a source file name). An existing way is using -g option to compile my software, then I can

Dear developers, When I try to map line numbers in source code back to LLVM basicblocks, I meet some problems: there is a source file with 1500 lines of code, but when I use BasicBlockPass to collect all DbgStopPoint instructions in this file, I can only get 500 lines of code. The source code and the collected results are both attached. Is there any way to map line numbers

Hi, It's taking me a while to get familiar with the cfe in order to add emitting stop points for debugging. It's a lot to work through, so in order to speed things up, I've got a few questions. Any help would be appreciated. I understand the design of the intrinsics once they're in the code, but how to generate them is still a little fuzzy, mainly because llvm_expand is a little

Hi, Im new to llvm and I'm using llvm-2.6 and I know how to extract the metadata in the stoppoints but what I'm interested in is the meta data regarding a local variable. I know that the @llvm.dgb.declare such as: call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable9 to { }*)) links to meta data for @llvm.dbg.variable9 which is:

I'm trying to track down the problem with the assertion failure in SelectionDAGBuilder.cpp. This is the code: *case* *Intrinsic*::gcroot: *if* (GFI) { *const* Value *Alloca = I.getArgOperand(0); *const* Constant *TypeMap = cast<Constant>(I.getArgOperand(1)); * FrameIndexSDNode *FI = cast<FrameIndexSDNode>(getValue(Alloca).getNode());*
