I need a help/advice how to go with the following problem.
There are two independently created patches https://reviews.llvm.org/D111114 and https://reviews.llvm.org/D107301 which actually handle the same problem.
There is pseudo instruction STATEPOINT and it is platform-independent.
However the list of implicit-defs is different on different platforms. Specifically on aarch64 it has implicit def of link register.
I failed to find a way how to override the list of implicit defs of pseudo instruction for some specific platform.
So I wonder
