Hi Mehdi,
I meant when I build the LLVM and it will give the following errors:
make[2]: Entering directory `/home/alex/new/llvm-obj/tools/llc'
llvm[2]: Linking Debug+Asserts executable llc
/home/alex/new/llvm-obj/Debug+Asserts/lib/libLLVMCodeGen.a(Passes.o): In
function `llvm::TargetPassConfig::addIRPasses()':
/home/alex/new/llvm-3.1.src/lib/CodeGen/Passes.cpp:295: undefined reference
to `llvm::createMyAliasAnalysisPass()'
collect2: ld returned 1 exit status
make[2]: *** [/home/alex/new/llvm-obj/Debug+Asserts/bin/llc] Error 1
make[2]: Leaving directory `/home/alex/new/llvm-obj/tools/llc'
make[1]: *** [llc/.makeall] Error 2
make[1]: Leaving directory `/home/alex/new/llvm-obj/tools'
make: *** [all] Error 1
Thanks,
Alex
