[LLVMdev] indirect calls tracking and control flow graph
Thank you,
I tried to compile it with llvm 3.4 through these commands:
petsas at shinigami:~/software/poolalloc$ ./configure
--with-llvmsrc=/home/petsas/software/llvm
--with-llvmobj=/home/petsas/software/llvm
petsas at shinigami:~/software/poolalloc$ make
but I'm getting get this error:
make[1]: Entering directory `/home/petsas/software/poolalloc/lib'
make[2]: Entering directory `/home/petsas/software/poolalloc/lib/DSA'
llvm[2]: Compiling CallTargets.cpp for Debug+Asserts build (PIC)
CallTargets.cpp:35:3: error: use of undeclared identifier 'DEBUG_TYPE'
STATISTIC (DirCall, "Number of direct calls");
^
/home/petsas/software/llvm/include/llvm/ADT/Statistic.h:165:38: note:
expanded from macro 'STATISTIC'
static llvm::Statistic VARNAME = { DEBUG_TYPE, DESC, 0, 0 }
^
CallTargets.cpp:36:3: error: use of undeclared identifier 'DEBUG_TYPE'
STATISTIC (IndCall, "Number of indirect calls");
^
...
Any ideas?
