Hi
According to gnu document of function attributes, neither weakref nor
alias
could be attached to a function defined in current translation unit.
Although GCC checks the attributes under some circumstances, it still
fails
on some cases and even causes ICE.
This patch checks whether alias/weakref attribute attaches on a function
declaration which has body, and removes the attribute later.
This also avoid the ICE.
Bootstrapped/regtested on x86_64-linux, ok for GCC10?
