similar to: [LLVMdev] Statistic API change

This is an FYI to all people who are writing LLVM passes (mostly 426 people) about a useful feature of LLVM. The "Support/StatisticReporter.h" file provides two useful features that you may want to make use of in your pass (http://llvm.cs.uiuc.edu/doxygen/StatisticReporter_8h-source.html): 1. Statistics output - Often you may run your pass on some big program, and you're

FYI. I just changed how statistics are defined. This eliminates one static constructor for each statistic in the system, causing them to be statically initalized instead. To update any out of tree code, change this: Statistic foo("blah", "desc"); into: #define DEBUG_TYPE "blah" // before any #includes ... STATISTIC(foo, "desc"); Statistics are

Hi, In the quest for better test cases for my MP, I thought of trying the Stepanov Abstraction Penalty benchmark. But apparently llvm-g++ is not ready for such terrible things. Let me know if you want me to send the source code (it is widely available). gaeke|csil-suna37|~/cs/426/MP1/step|[1177]% /usr/dcs/projects/cs426/Software/gcc_install/bin/g++ stepanov.cpp -o stepanov In file included from

Just a note: I just checked in a change that corrects some very non-intuitive behavior of the AllocaInst & MallocInst classes. Before, the constructor would take a Type which would specify the return type of the instruction, instead of the operand type. Now it takes the operand type directly. More concretely: LLVM Code: X = alloca int ; int* Y = malloc int * ; int** Old C++

I just checked in an important change to the LLVM Verifier pass, and have compiled a new version of the GCC front-end. The big change is that we now match the LangRef.html much more closely: many operations on pointer operands are illegal. Essentially, the GCC front-end should never generate adds, subtracts, multiplies, divides, rem, or shr/shl instructions that take pointer operands now. In

Dear Prof. Adve, Now I can use llvmgcc to compile a .c file into .bc file. But I still have trouble simply run the .bc code. Below is the sequence I got when I tried. I really don't know what's going on here. Please let me know how can I fix it.

Just a warning that the LLVM web site and CVS server are likely to be affected by the following maintenance work on May 21. Many of our software utilities are automounted from DCSfiles. --Vikram http://www.cs.uiuc.edu/~vadve http://llvm.cs.uiuc.edu/ Begin forwarded message: > From: "Frank E Penrose" <fep at uiuc.edu> > Date: May 9, 2006 9:01:38 AM CDT > To:

The problem with llvmgcc invoking as instead of llvm-as has been fixed. 3 llvm-specific executables needed to be copied into a default location where gcc can find them if it does not find them as configured (gcc was configured for the paths on our research machines and copied over). Let us know if you have additional problems. --Vikram > -----Original Message----- > From: llvmdev-admin

Thank You. Actually i pass polly canonaclize IR to my new created polly pass called "mypass". Mypass should first detect scops then find depedndencies as the mechanism conventional approach. Now i know how to write llvm pass here i am writing pass as loadable module first afterwards i will integrate it with opt in the end. I tried writing following code. Could you please help me on

Hello LLVM, I am following the document "Writing an LLVM Pass". When I ran "opt -load ../../../Debug/lib/MyPass.so -mypass < hello.bc > /dev/null" I got the next error: ***@ubuntu:~/test$ opt -load ../../llvm/Debug/lib/MyPass.so -mypass < hello.bc > /dev/null opt: Pass.cpp:159: void<unnamed>::PassRegistrar::RegisterPass(const llvm::PassInfo&): Assertion

Hi again, I come back to this issue with an example. It's a pass which does nothing but throw the 'Unable to schedule' error. namespace { struct MyPass : public FunctionPass { static char ID; // Pass identification, replacement for typeid MyPass() : FunctionPass(ID) { initializeMyPassPass(*PassRegistry::getPassRegistry()); } virtual void

Hi guys, I am writing a LLVM pass plugin, and just simply add a directory mypass into llvm/lib/Transforms. But since I don't hope this directory to contain too many source files, I add some subdirectories. For instance, there are 2 files inside *mypass/sub: basic.h, basic.cpp. Here is the structure of the directory llvm/lib/Transforms/mypass $tree mypass mypass ├── Makefile ├──

Hello, I want an instance of CallGraph in my pass. By looking at -dot-callgraph source, I've tried something like this: CallGraphWrapperPass *CGWP = new CallGraphWrapperPass(); PM.add(CGWP); CallGraph *CG = &CGWP->getCallGraph(); PM.add(new MyPass(CG)); I get the following error: /home/riyad/installs/llvm-3.7.0/include/llvm/PassSupport.h:95:38: error: no matching constructor for

How do you compile the code? Within the Polly subdirectory using CMake? How do you run your pass. Using "opt -mypass inputfile.ll"?

I looked into that already, but Statistic.h only gives me the possibility to implement tracking

Hi everyone again, I did discover the following works (see below).
