[cfe-dev] Clang Executable Debugging with GDB

[Luke Mauldin]

Hi all,

I have built a simple executable with Clang (build commands are below) and
I am trying to debug the executable with GDB.  I am able to set
break-points in GDB and step through the code but no information about
variables is available.  Is this a known limitation of Clang and GDB or I
am doing something wrong?

clang++ -O0 -emit-llvm -g3 -Wall -c -fmessage-length=0 -o src/main.bc
../src/main.cpp
llvm-ld -v -L/usr/lib/gcc/x86_64-linux-gnu/4.7/ -native -o
