Hi all, I am trying to write a pass for the llc tool. I register this pass with the RegisterLLC template. However, when I try to run llc and load up the pass, I get a failed assertion: $ /storage/anshuman/llvmCVS/llvm/tools/Debug/llc -load=./libTest.so --help ... ... llc: Pass.cpp:327: void llvm::RegisterPassBase::unregisterPass(llvm::PassInfo*): Assertion `I != PassInfoMap->end()

Dear All, The attached code (which is a contrived test case) hits the following assertion: test: /home/vadve/criswell/src/llvm22/include/llvm/PassAnalysisSupport.h:226: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*, llvm::Function&) [with AnalysisType = Pass1]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not "

Hi all LLVMor, I just tried to compile a simple code and analyze the number of the basic blocks. But after compile, what I got, the bytecode is seems to be optimized bytecode. So the information of basic blocks is not what I expected. I want ot use the code as example to see how some of code optimization methods work. However, after compiling file using llvm test.c -o test, bytecode file

I am investigating some inlining issue, so I did llvm-gcc aaa.c bbb.c ... nnn.c -o output opt -inline -inline-threshold=xxx < output.bc | llc -march=c > output_inline.c 1) I noticed that even if I set xxx to 0 or even a very small negative number, many functions are eliminated. I am wondering if these functions are inlined by the frontend, or identified as deadcode. For instance,

I know that Al Stone has compiled llvm-gcc4 successfully and I can report the same. The problem I consistently run into is that llvm-gcc ends up producing native format output; it does not produce bytecode, nor does it invoke gccas or gccld. I'm using the latest svn, and my configure args are: --prefix=/work/scottm/llvm-cfrontend/obj/../i686-pc-linux-gnu \

That would mean that the "An Example Using the LLVM Tool Chain" section needs to be updated for the gcc4 frontend. OTOH, I could

However, I do know that your methods above run the LLVM inlining pass, albeit indirectly. If you use

Hi, I'm able to build the llvm tools on the MinGW platform: burg, fpcmp, tblgen, llvm-as, llvm-dis, opt, gccas, llc, llvm-link, lli, gccld, llvm-stub, analyze and extract. I wonder if these tools are sufficient to start build the cfrontend?

Hi devels, there are two issues concerning invoking optimizations: 1. this document: http://llvm.cs.uiuc.edu/docs/GettingStarted.html is very nice, it would be good though to add in a section An Example Using the LLVM Tool Chain examples on optimization step. 2. If i am not wrong there is no tool, which integrates all steps: llvmgcc->opt->llc into something like llcc (and

I don't think llvm-gcc4 uses gccas or gccld, but it can emit bytecode if you give it the --emit-llvm option: llvm-gcc --emit-llvm -c -o foo.bc foo.c On 8/14/06, Scott Michel <scottm at rushg.aero.org> wrote: > I know that Al Stone has compiled llvm-gcc4 successfully and I can > report the same.

hello everyone, I few days ago I had some code (for the PyPy project) that llc - march=c converted to a switch statement and gcc compiled that nicely to a jumptable in the .s file. Now I try to reproduce when directly going from a .ll to a .s file. But I now see a long list of compare and jumps instead of the jumptable. Is there a transformation that does this if->switch(ing) or is

I was thinking of something simple like this: [.c] compile = cc1 %in -o %out optimize = gccas %in -o %out.bc link

Perhaps I am missing some link. Need a bit clarification. For the C language, I want to access the LLVM code immediately generated by llvmgcc(cfrontend/bin/gcc) before it undergoes any further transformation or optimization. 1) Are there any libraries that enable me to parse C code and create the Module instance. 2) If answer to 1) is no, then is there some other way to create Module
