--- Comment #1 from Vlad Tsyrklevich <vlad at tsyrklevich.net> ---
I never followed-up on this. The size increase for nacl_helper was eliminated
by enabling summary emission for the regular LTO portion of the build [1] and
only emitting jumptable entries if functions are address-taken in live
functions (rather than just being address-taken in live or dead functions.)
Though this doesn't address the case of bitcode->native->bitcode references,
this did not turn out to be a factor in the nacl_helper size increase. Closing
as the size increase has been fixed.
