...e. I've read that AA needs a call to InitializeAliasAnalysis(this) in the main run method (in my case, runOnFunction), and I'm wondering how to properly implement it, since the parameter is supposed to be a Pass.

...aving trouble getting this to work. I was told to also modify include/llvm/LinkAllPasses.h to add a call to (void) llvm::createRelRecoveryPass(); which I have done, but when I go to my main llvm-obj directory to build llvm so that the call is valid when I actually compile my pass files, I get: /x/grwright/llvm/llvm-obj/tools/opt/Debug+Asserts/opt.o: In function `ForcePassLinking': /x/grwright/llvm/llvm-2.9/include/llvm/LinkAllPasses.h:152: undefined reference to `llvm::createRelRecoveryPass()' So how do I fix that? Where do I need to be defining this? In addition, when I try to just compi...

Hello, I've been stuck with a problem for about a month, and it has stumped everyone in my lab. I have a function pass that runs, and when it finishes and opt goes to return, I get: While deleting: void % An asserting value handle still pointed to this value! UNREACHABLE executed at /x/grwright/llvm/llvm-2.9/lib/VMCore/Value.cpp:569! On a simple test case, the error becomes 'i32 %' instead of 'void %'. I cannot for the life of me figure out what is happening. I'm not deleting anything extra internal to my pass that I can tell, and I'm not sure how to go about de...

Hello, I'm working on an LLVM IR pass and would like to insert comments into the generated .bc file during the pass. I've been having trouble finding documentation for this process, and was wondering if there is a simple way to do it. At the moment, I have a stringstream whose .str() I'd like to stick in this generated file every once in a while. Thanks, Griffin Wright

I tried using 2011-03 for gnu/linux, but I got the exact same problem. -Griffin On Jul 27, 2011 9:29 PM, "陳韋任" <chenwj at iis.sinica.edu.tw> wrote: > > Hi, Griffin > > > /net/coldwater/w/grwright/Research/llvm/arm-2010q1/bin/arm-none-linux-gnueabi-as: > ^^^^^^^^^^^ > > Maybe using a newer codesourcery toolchain can help you? > > Regards, > chenwj > > -- > Wei-Ren Chen (陳韋任) > Computer Systems Lab, Institute of Informatio...

Hello all: I apologize for what I imagine is a rather silly question, but I'm still somewhat new to LLVM and am stuck. I am reworking some code that was originally in the backend involving MachineInstructions and MachineOperands, and I now need for it to function as an LLVM IR pass, using just Instructions, etc, and nothing related to 'Machine'. However, I am not sure how to get the
