Hi, all,
Sorry for bothering.
I'm trying to commit aarch64 scs code to the gcc and there is an issue
that I'm not sure about, could someone give me some suggestions?
(To avoid noise, I did't cc PING^3 [1] to the kernel mail list :) )
When clang enables scs, the following instructions are usuall

Usually we handle DR1558 substitution near the top of tsubst, but in this
case while substituting TYPENAME_TYPE we were passing an alias

Given build_this of a TARGET_EXPR, cp_build_fold_indirect_ref returns the
TARGET_EXPR. But that's the wrong value category for the result of the
defaulted class assignment operator, which returns an lvalue, so we need to
actually build the INDIRECT_REF.

containing allocatable and non-allocatable scalars. Furthermore does it prevent
broadcasting of coarray-tokens, which are always local this_image. Thus having
them on a different image makes no sense.
