------- Additional Comments From schlie at comcast dot net 2005-02-20 06:44 ------- (In reply to comment #7) With respect to: <http://gcc.gnu.org/ml/gcc/2002-01/msg01872.html> and paradoxical subreg semantics on targets which support modes_tieable (assuming that paradoxical subreg semantics applied to tied registers):
- It would seem that a paradoxical subreg need not have a memory operand (as it would valid to be able to store a known lesser precision value in fewer tied registers than the type that it logically represents may otherwise require)? - nor does it seem to make sence in any circumstance to referance a wider logical value than may be stored in a register or memory, without presuming it's higher-order bits are of some known value (unless it's known that they're logical value were to be effectivly replaced by the operation without regard to it's initial value)? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=5169
