--- Additional Comments From matz at suse dot de 2005-02-17 22:06 ---
I think that #19566 is a real bug. The ABI specifies to pass 16byte
structs in registers. Anyway MAX_FIXED_MODE_SIZE doesn't influence
the calling convention, only how such struct is handled by transforming
code.

The problem is that we reset TREE_OVERFLOW:
It would seem it overflows incremented, and underflow's decremented,
only a terminal non-zero count would represent an over/underflow for
This is a very small testcase, in which the code generated by gcj does not
