Hi. Can you please elaborate the issue a bit more and share with me the following information 1) what subject program you are working on and its version, 2) OS version and LLVM version. I also need all the commands to reproduce the issue before providing any suggestion.
from aflgo.
project: imagemagick 7.0.3-8
system version: Ubuntu 16.04
llvm version : LLVM 7.0
commands:
export CC=/home/lt/aflgo/afl-clang-fast
export CXX=/home/lt/aflgo/afl-clang-fast++
export SUBJECT=/home/lt/imagemagick/ImageMagick
export TMP_DIR=$SUBJECT/temp
mkdir TMP_DIR
echo "attribute.c:641" > TMP_DIR/BBtargets.txt
export AFLGO=/home/lt/aflgo
export COPY_CFLAGS=$CFLAGS
export COPY_CXXFLAGS=$CXXFLAGS
export ADDITIONAL="-targets=$TMP_DIR/BBtargets.txt -outdir=$TMP_DIR -flto -fuse-ld=gold -Wl,-plugin-opt=save-temps"
export CFLAGS="$CFLAGS $ADDITIONAL"
export CXXFLAGS="$CXXFLAGS $ADDITIONAL"
./configure --prefix=/home/lt/imagemagick/ImageMagick/install
make
make install
cat $TMP_DIR/BBnames.txt | rev | cut -d: -f2- | rev | sort | uniq > $TMP_DIR/BBnames2.txt && mv $TMP_DIR/BBnames2.txt $TMP_DIR/BBnames.txt
cat $TMP_DIR/BBcalls.txt | sort | uniq > $TMP_DIR/BBcalls2.txt && mv $TMP_DIR/BBcalls2.txt $TMP_DIR/BBcalls.txt
$AFLGO/scripts/genDistance.sh $SUBJECT $TMP_DIR identify
when I execute the command "$AFLGO/scripts/genDistance.sh $SUBJECT $TMP_DIR identify", there is no distance.callgraph.txt.
The content of the callgraph.dot file is as follows:
digraph "Call graph" {
label="Call graph";
Node0x2a0e850 [shape=record,label="{external node}"];
Node0x2a0e850 -> Node0x2a0e8f0;
Node0x2a0e8f0 [shape=record,label="{main}"];
}
So, how could I solve this problem?
Thank you for your helping!

Please try with LLVM-4.0 or LLVM-3.8. There is some LLVM version specific issues and we will try to fix them asap. It could be some issue of LLVM itself.
