No. In GCC 4.3.2, in the machine description for the avr (gcc/config/avr/avr.md), there is define_insn "abssf2" that will use the T bit. It generates a CLT and BLD instructions. However, I have no idea how often the define_insn "abssf2" will trigger. But yes, there is a possibility. And of course gas is aware of the SET and CLT instructions.
