All of this is defined by the Spec subdirectory of the test in the SPEC 
distribution.  Note that different problem inputs (test/ref/train) are not 
different compile-time options, they are different input files and command 
line arguments.  If you look at the LLVM llvm-test makefiles, this 
information is also encoded.  From the 126.gcc makefile, for example, 
you'll see:

RUN_OPTIONS := -quiet -funroll-loops -fforce-mem -fcse-follow-jumps 
-fcse-skip-blocks -fexpensive-optimizati
ons -fstrength-reduce -fpeephole -fschedule-insns -finline-functions 
-fschedule-insns2 -O -o -

ifeq ($(RUN_TYPE),test)
STDIN_FILENAME = cccp.i
STDOUT_FILENAME = cccp.s
else
STDIN_FILENAME = amptjp.i
STDOUT_FILENAME = amptjp.s
endif

Note that llvm-test compiles the benchmarks a file at a time (with -c), 
not all at once.
