Can you verify one of the object files to see if the compiler has inserted the
NOPs or not ? Just take one of those source files containing other routine(s),
and produce an assembly listing  (.s) file with -S +pal +O2 options. Just 
check  if you see a Branch instruction (B) followed by a series of NOPs in 
the routines ? If yes then probably compiler is OK.  Next preinstrument the 
binary, and check to see if there are calls __cxperf_prev* routines inserted 
by cxperf. 
(if you don't know how to check the latter, drop me a mail offline). 

Are you using -g and +O2 ? Only then probably there is a chance that 
you will get "DOC: add range: invalid base instruction".
