https://sourceware.org/ml/binutils/2017-03/msg00261.html describes
as-of-yet-unimplemented attributes to control the placement of data into new
variants of bss, data, etc.
> The goal is to place data in special memory sections via
> attribute. To place an uninitialized variable, foo, in a
> mbind bss section with memory type 1:
>
> int foo __attribute__ ((mbind(0x1)));
>
> To place a variable, foo, in a mbind data section with
> memory type 2:
>
> int foo __attribute__ ((mbind(0x2))) = 1;
>
> To place a read-only variable, foo, in a mbind rodata
> section with memory type 3:
>
> const int foo __attribute__ ((mbind(0x3))) = 1;
This is a feature request to support these in GCC, since the underlying
functionality is supported
(https://fossies.org/diffs/binutils/2.28_vs_2.29/include/ChangeLog-diff.html).
