I'm not familiar with the SPARC but it sounds as if you need to read the
description of the GCC option -fomit-frame-pointers. Frame pointers are
used to chain call stacks together but some forms of optimization
prevent them from being used. For example they're often omitted in
functions that call no other functions, so-called "leaf" functions.
Alas, omitting frame pointers can make complete backtrace listings
impossible. You can try using -fno-omit-frame-pointers after specifying
the optimization level.
