[llvm-dev] [Help] Problem on running SPECInt 2006 with LLVM

[Sunghyun Park via llvm-dev]

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

Any advice will be a great help.
Thank you!

Best, Sung
