similar to: [LLVMdev] Removing unused function definitions

I thought this pass would do it, but when I run it over my bc file the output file is the same as the input file. The issue I guess is a little different. When I link in the huge bc file with the tiny bc file, I only want the resulting bc file to have the function definitions that the tiny bc file requires and not every function in the huge bc file. Any idea's how to do this with the

Hi all, I too am getting this error for x86_64 when I am trying to use the Data Structure Analysis ...I svn upped both the llvm main branch and the poolalloc today in the morning and recompiled everything from scratch : $ opt -load /home/pprabhu/llvm/llvm-install-x86-64/lib/libpoolalloc.so -ds-aa < o.bc opt: /home/pprabhu/llvm/llvm/lib/VMCore/PassManager.cpp:1418: virtual void

Hi, I am trying to use the poolallocator. More specific, I am trying to play around with the pointer compression pass. Though, I get assertion failures for the pass dependencies. This is when it in PointerCompress::getAnalysisUsage tries to register the the BU pass as required. I.e. when AU.addRequired<CompleteBUDataStructures>(); is called. $ opt -f -load

Is there a way to mark all functions as internal from source via some sort of attribute?

Dear Prakash, I believe I've fixed the problem you were having with ds-aa. Please update your poolalloc tree, recompile, and let me know if it works. -- John T.

Hi I create a simple bytecode file with clang -c -emit-llvm test.c -o test.bc #include <stdio.h> void hello(){ printf("hello\n"); } void hello2(){ printf("hello2\n"); } Then i want to keep only the hello function so i do : llvm-extract -func=hello -o test2.bc test.bc but the string constants are removed and "@.str" is marked as external @str

Dear Prakash, Yes, DSA is still in active use, although nobody else uses the -ds-aa pass as far as I know. I tried the below sample (although ds-aa should be in libLLVMDataStructure.so and not libpoolalloc.so), and I get the same error. I've seen similar problems with other passes in our work here. My guess is that -ds-aa is requiring two passes that claim to invalidate each other; this

Hi, I'm having some problems with producing native executables with llvm-ld. Both TimberLLVMLIB and TimberLLVMRTS is compiled into bitcode files and archived with llvm-ar. Everything works fine when using the flag -disable-opt llvm-ld -Xlinker='-pthread' -Xlinker='-m32' -native -disable-opt -L/home/capitrane/local/timber-llvm//share/timberc-1.0.3/rtsPOSIX ConcMap.bc

In order to handle a large vector based math library I link in a fairly large bitcode file that might or might not be needed. The problem is that linking in this bitcode file drastically increases the amount of compile time required. Is there a way to remove all functions that are not used after this linking pass? Something similar to die but removes functions from the compilation unit instead of

Hey Jingyue, Though I tried `opt -nvvm-reflect` on both bc files, the nvvm reflect anchor didn't go away; ptxas is still complaining about the duplicate definition of of function '_ZL21__nvvm_reflect_anchorv' . Did I misused the nvvm-reflect pass? Thanks! yuanfeng On Fri, Mar 11, 2016 at 10:10 AM, Jingyue Wu <jingyue at google.com> wrote: > According to the examples you

Thanks I let GParted create the file system. It was done on a rescue disk of Ubuntu 12.04 (GParted 0.11.0) I think that the problem is in my command line.

Hi, I needed to compile a cuda source file (say, a.cu) into IR (a.bc), and then merge a.bc with another bitcode file (b.bc, compiled from b.cu). So I used *llvm-link a.bc b.bc -o c.bc* However, I noticed that an internal function '* _ZL21__nvvm_reflect_anchorv() *' is defined in both a.bc & b.bc, and when merging these two files, one of the two definitions was renamed to

Mark all functions apart from the kernel entry points with the internal attribute and then run global dead code elimination (it should remove most
