I want to compile SPEC2006 using opencc. The configuration file I am using is the linux64-amd64-gcc41.cfg provided with SPEC2006. The compiler path is set as follows:

CC           = /home/qgw/src/open64/local/bin/opencc
CXX          = /home/qgw/src/open64/local/bin/openCC
FC           = /home/qgw/src/open64/local/bin/openCC

Since there was an error during the installation of Fortran, I haven't dealt with the Fortran test programs yet.

make whirl2f.so whirl2f_be whirl2f
make[3]: Entering directory“/home/qgw/src/open64/build/osprey/targdir/whirl2f”
if ! test -e maccom.so; then ln -sf /home/qgw/src/open64/build/osprey/targdir/be/maccom.so .; fi
C++    /home/qgw/src/open64/build/osprey/targdir/whirl2f/diagnostics.o
g++: error: maccom.so: No such file or directory

The optimization options are set as follows:

default=base=default=default:
COPTIMIZE     = -O2 
CXXOPTIMIZE  = -O2 
FOPTIMIZE    = -O2

To compile the integer benchmarks of SPEC2006, the following command is used:

runspec --config=x86.try.cfg --size=test --noreportable --tune=base --iterations=1 --speed --action=build int

The compilation result is as follows:

Build errors: 400.perlbench(base), 401.bzip2(base), 403.gcc(base), 456.hmmer(base), 464.h264ref(base), 471.omnetpp(base), 473.astar(base), 483.xalancbmk(base)
Build successes: 429.mcf(base), 445.gobmk(base), 458.sjeng(base), 462.libquantum(base), 999.specrand(base)

The detailed error message for 400.perlbench is as follows, and the other benchmarks have the same error:

### Assertion failure at line 1524 of /home/qgw/src/open64/build/../open64-w2ll/osprey/be/opt/opt_etable.cxx:
### Compiler Error in file av.c during Global Optimization -- SPRE: Iphi Insertion phase:
### EXP_WORKLST::Are_different:  must not reach here.

There is an internal assertion error. Can opencc now compile SPEC2006, or are there any additional options that need to be set in the cfg file?

A few months ago, we executed SPEC2006 using Open64 5.0 (master branch). I suspect that this bug has emerged due to optimizations developed subsequently. You can try the 5.0 version. I am going to look into this bug.
