Compiling SPEC Benchmarks tools on ARM

Some of the SPEC benchmarks come for a variety of architectures but not for ARM, which is not surprising anyway. The easiest way to execute the benchmarks is by using the provided scripts, which is pretty much straight forward operation. The benchmarks come with pre-compiled tools and libraries that are needed by the benchmarks. Among them is Perl, which will fail to compile on ARM systems because of some invalid object definitions in its makefile. These definitions get in the makefile by the Configure script which is called before calling make. Instead of messing around with Configure, I added a couple of lines in the buildtools file, which is responsible for building the SPEC tools on a new architecture or after having modified the host system, in order to remove the unnecessary lines from the corresponding makefiles.

The buildtools script can be found under tools/src/ in the SPEC benchmarks directoy. What is needed is to go in the Perl building section, line 103, and replace the fist part of the building phase with the following oneliner:

(cd $PERLSRC; LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH; 
./Configure -dOes $PERLFLAGS -Ddosuid=undef -Dprefix=$INSTALLDIR 
-Dd_bincompat3=undef; cat makefile | grep -v built-in 
| grep -v "command line" > makefile.new; cp makefile.new makefile; 
cat x2p/makefile | grep -v built-in | grep -v "command line" > x2p/makefile.new; 
cp x2p/makefile.new x2p/makefile; make; ./perl installperl ) 
|| die "Can't build perl"
