This is wrong, carry flag propagation is broken between these two asm

Attached to this message, please find definitions of
__FP_FRAC_{ADD,SUB}_{3,4} macros, together with a test application.
Here is the updated patch. I had to comment out __FP_FRAC_SUB_4
since I got
/export/gnu/src/gcc/gcc/libgcc/../gcc/config/soft-fp/divtf3.c:44:
error: can't find a register in class ‘GENERAL_REGS’ while reloading ‘asm’
/export/gnu/src/gcc/gcc/libgcc/../gcc/config/soft-fp/divtf3.c:44: error: ‘asm’ operand has impossible constraints
OK for trunk? Thanks.
