--- Comment #1 from Fangrui Song <i at maskray.me> ---
% cat a.s
.symver my_test, test at TEST
.comm   my_test,4,4

% as a.s -o a.o
a.s: Assembler messages:
a.s: Error: `test at TEST' can't be versioned to common symbol 'my_test'

Now that GCC 10/Clang 10 default to -fno-common, this issue is moot.
