; Stub double-precision soft-float — every routine returns 0.
;
; The C-based softDouble.c hit two compiler issues simultaneously:
; (1) Register Coalescer crash on the multi-tied-def-with-i64 pattern;
; (2) PEI "frame offset out of stack-relative range" because the
; spilled u64s push the local frame past the 8-bit ,S addressing
; limit.  Both are real compiler bugs that require non-trivial
; backend work to fix.  Until then, these stubs let programs that
; reference but don't actually evaluate `double` link cleanly;
; programs that DO use double get zero values back.
;
; Symbol set matches what clang's i64-routed double libcalls expect.
; ABI: i64 result returned via A:X:Y:DP[$F0] (matches LowerReturn).
