Hi,
this is patch fixing the underlying issue of function missing
lto_prepare_function_for_streaming because gimple_has_body_p is not the
same thing as node.has_gimple_body (which needs to be clarified next
stage1 by finding better names for this I suppose).
I commited it to gcc 11 even though we already have your workaround
since it is small and safe and it may save some pain when backporting
changes to the branch in future - basically all passes at WPA
renumbering statements would hit this issue which is not that obvious to
debug as we found :)
We may backport it to gcc10 too if you preffer it over your fix - I
think both are fine in general for release branches.
lto-bootstrapped/regtested x86_64-linux.
