Sorry about the confusion.  SRC_ROOT and OBJ_ROOT are not environment 
variables that you need to set.  SRC_ROOT is shorthand for the directory 
containing the LLVM source, and OBJ_ROOT is the shorthand for the 
directory in which LLVM will be built.  They are simply terms which are 
convenient and make typing easier.

I think your configuration for SPEC95 is not going to work.
Our configuration expects that you're using the same directory tree in 
which SPEC95 was shipped to you on the CD.  The only difference between 
our SPEC95 code and that found on the CD is a few fixes for compilation.

One thing you can try is to rename the INTEGER directory to CINT95.  In 
other words, set the variable SPEC95_ROOT in Makefile.config to 
/Fast-System/spec95 and put the integer benchmarks in 
/Fast-System/spec95/CINT95.

Now, if you do that, I believe it should work, as long as everything 
below CINT95 is exactly the same as it is in the SPEC95 CD.  If the 
directory /Fast-System/spec95/CINT95/099.go doesn't look like this, then 
you may still have problems:

DEBUG
DESCR.go
Makefile
README.go 
         Spec
VERSION 
         data
exe
result
run 
         src
