The float encoding issue was re-confirmed here.

I'm not sure if we meanwhile have a per-file LTO header but it might be
nice to put enough info there to give a reasonable error.  As said
endianess is a hard issue to fix, likewise int/long/pointer size difference=
s.
The float encoding part could be fixed in theory.

target specific issues with host dependences might also exist (host
dependent flags might be streamed?).

Regression testing is another obvious problem here.=
