For avr, there is no support for shared objects, yet
when building libgcc, for each module.o there is also module_s.o
that's build with -DSHARED.
How can this be turned off?
What doesn't word is to configure with --disable-shared, and even
without turning it off by hand, there is no use for modu

The recently pushed hreg-constraints (HRCs) feature has this in
the docs:
register asm may not only be clobbered by function calls but also by
inline asm in conjunction with hard register constraints. For example,
in the following
register int x asm ("r5") = 42;
int y;
asm ("" : "={r5}" (y))
15 matches
