But apparently RA believes it has to, to satisfy some constraints. Difficult to say exactly, without a little more context. Cross-compiler from what to what? What else does spill_failure print? spills.txt only shows the ICEs, but spill_failure prints a lot of information about what failed -- that's actually useful information for folks willing to help here but not willing to build a cross-compiler for it ;-)
