The Sparc assembly writer cannot emit 2 functions of the same name that both
have non-empty 
constant pools, because it mangles the names of constant pool members
incorrectly: the first entry in 
each constant pool for all functions named "foo" will be named ".CPI_foo_0",
but the latter "foo" should 
have been mangled.

This should be fixed now:
