--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
We can add patterns to support
(call (mem:QI (zero_extend:DI (mem/u/c:SI (const:SI (unspec:SI [
(symbol_ref:SI ("bar") [flags 0x41] <function_decl
0x7f19fd7bbbd0 bar>)
] UNSPEC_GOTPCREL)) [1 S4 A8])) [0 bar S1 A8])
(const_int 0 [0]))
It is "call *bar@GOTPCREL(%rip)"
