--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Doesn't ICE with C, where it is rejected with:
pr84961.c: In function ‘foo’:
pr84961.c:3:15: error: lvalue required in asm statement
 void foo () { asm("" : "=a"(b = a)); }
               ^~~
pr84961.c:3:15: error: invalid lvalue in asm output 0
But in C++ b = a seems to be considered as lvalue.
Let me have a look...
