BBandClaude Opus 5.5 e016974a2e Lower 64-bit fixed_point_div with 128-bit division ...

LLVM legalizes a 64-bit sdiv.fix or udiv.fix whose dividend does not
fit by widening it to a 128-bit division with remainder, for which no
target has a library call, so code such as fixed_point_div(x, y, 63)
on i64 aborted with "unsupported library call operation".

64-bit fixed point division is now built from plain 128-bit division
and remainder, which lower to __divti3 and friends, rounding down and
saturating as LLVM's expansion does. Results for the scales LLVM could
already handle are unchanged.
