I am not sure if a bug report is the right place for this feature request, but
it addresses a potential future compatibility to GCC issue.

GCC 10 has a new variable attribute: noinit.

https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html#index-noinit-variable-attribute

https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;a=commit;h=f0033821c1c9ba386a1983499a666d5759cdd943

Maybe clang could support this as well. The new attribute is not just a wrapper
for section(".noinit"). In addition, the linker needs to support this section.
