[PATCH 2/4] PDP11: Use a mode with `const_double_zero' expressions

2021-01-07 Thread Maciej W. Rozycki
For predictable semantics propagate the mode from operands referred by FP substitutions to the `const_double_zero' expressions used with the associated condition code calculation, resulting in the following update to insn-emit.c code produced for the `pdp11-aout' target (with machine descriptio
