`gcc -S` can be used to compile the source to assembly. The C source contains static variables named `shr` and `si`, which get compiled to something like.lcomm shr,8,8 .lcomm shi,8,8 .lcomm sr,8,8 .lcomm si,8,8
Not these, but
mov rdx, QWORD PTR shr[rip]
Maybe GCC shouldn't generate this syntax (Clang doesn't) [1], or it gets misinterpreted by AS.
Anyway `-masm=att` will solve this issue.
