Hi Asit, thanks for the reply. But I guess I was not clear in my question. Actually, i dont want to use __ATTRIBUTE__((ANNOTATE("MOVIATTR"))), since in documentation it is stated that "This intrinsic allows annotation of local variables with arbitrary strings. This can be useful for special purpose optimizations that want to look for these annotations. These have no other

Hi John, I have looked into the EmitAutoVarAlloca() in CGDecl.cpp. However, I could not figure out how to employ my custom attribute for code generation. For example, my custom attribute is visible in CGDecl.cpp but how can I generate based on my custom attribute if (D.hasAttr<myCustomAttri>()) { //What to do here? } What I wan in IR is something like below. Without Custom Attribute:

> opt -load lib­dum­my­pass.so -dum­my­pass hel­lo.ll Looks like you are loading a shared library different from "LLVMHello.so". did you change the name of the compilation unit from "Hello.cpp" into "dummypass.cpp"? (As asked previously by Andrzej) did you register the dummy pass? > RegisterPass<DummyPass> X("dummypass",

Hi All, I need your guidance about a custom attribute. I have defined one for variables. It is accepted in the source code (without any warnings from clang), for example in following snippet. #define NEWATTR __attribute__((moviAttr(1))) int main() { NEWATTR volatile unsigned int a = 5; volatile unsigned int *p; p = &a; return (a+*p); } and actually when I Dump the declaration, after

I figured that my opt command is wrong! How to specify the output file anyway?? if I want hello.bc to be input file and newhello.bc to be output file, is the opt command go like this? opt -load ../../../Debug+Asserts/lib/Hello.so -hello <hello.bc> -o newhello.bc ?? -- 祝好！ 甄凯

My friends, I ran a function pass on a .bc file, intending to insert a CallInst to my self-made check function. The compilation is successful. BUT after I ran that pass on the .bc file, the size of the file didn't get any bigger!! Does this mean my instrumentation work failed?? BTW the opt command I use is "opt -load ../../../Debug+Asserts/lib/Hello.so -hello <hello.bc> -o

Dear sir or madam, I am a 4-th year student at Yerevan State University, Armenia; and I am studying LLVM in order to write my Bachelor thesis. I am trying to write an llvm pass that just removes all "Add" commands and gives some statstics. Nevertheless, I get this segmentation fault: ................some rows about functions, that are not changed by my pass. The errors occurs after it

Hi, I am following the instructions on Writing an LLVM Pass on Darwin(8.7.0) powerpc. The loadable library is built. But "opt -load " gives error saying "Symbol not found". I am using LLVM 1.8. Could someone tell me how to fix it? I have tried the same procedure on Pentium4 Redhat9. Everything is ok there. So I think there must be some specific problem on Darwin that I should

Hello all, I was playing with LLVM pass. I changed the lib/Transforms/Hello/Hello.cpp 's content to be my own pass. Then I make install the pass and use an example test1.c to see whether it works or not. When I run example using the following command: clang -emit-llvm test1.c -c -o test1.bc opt -load ../build_llvm/Debug+Asserts/lib/LLVMHello.so -hello < test1.bc > /dev/null It

I recently had a problem creating LLVMHello. I used this CMake file #!/bin/sh # clangcmake.sh cmake -G "Eclipse CDT4 - Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE="Debug" -DCMAKE_ECLIPSE_VERSION=4.5 -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang ../llvm then I ran make LLVMHello and the build failed

Thank you, Reid. I have applied tha patch to ltdl.c ltdl.h. The problem still exists. I looked up the symbol on libLLVMCore.a, and found three U-entries and one T-entry. However, the Darwin linker is not able to find the T-entry. Any idea? pollux:~/test jingyu$ opt -load /Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so -help Error opening

Hi, what's the current state of being able to build simple analysis passes out-of-tree against only llvm headers and libraries with llvm-config? I see that clang and klee do not use llvm-config but for example rubinius does. Should both approaches be documented? Currently for example docs/WritingAnLLVMPass.html says "you need to create a new directory somewhere in the LLVM source
