It would help if you specified the target and the compiler version that
you used.
The compiler I have (~4.5) places myint and mystr in .sdata; since
they're so small, GCC thinks that placing myint and mystr in .sdata is
beneficial. Why do you think -G 0 should be the default?
It does seem kind of odd that "mystr" is placed in .sdata, since
rs6000_elf_in_small_data_p indicates that string constants shouldn't be
in .sdata. You could investigate and submit a patch or file a bug.
