Hi, all. I'm trying to analyze SPECInt 2006 with LLVM and face errors on some programs.
I modified the configuration in makefile tree so that each source code generates its byte code instead of an object file.
Then, I combined all the generated byte codes into a single byte code and run it directly with lli.
The approach works with several benchmarks (e.g. bzip) but not all of them.
Certain benchmarks like "471.omnetpp" or "483.xalancbmk" halt their execution with segmentation fault. Interestingly, both benchmarks are implemented C++.
Do I need to add certain optimization flag?
I'm only using the flags as follows: -static -emit-llvm -O2
