force-indirect-call-2.c: Allow indirect branch via GOT
r15-1619-g3b9b8d6cfdf593 changed the codegen from
f2:
.cfi_startproc
pushq %rbx
.cfi_def_cfa_offset 16
.cfi_offset 3, -16
movq f1@GOTPCREL(%rip), %rbx
call *%rbx
leaq f3(%rip), %rax
call *%rax
movq %rbx, %rax
popq %rbx
.cfi_def_cfa_offset 8
jmp *%rax
.cfi_endproc
to
f2:
.cfi_startproc
subq $8, %rsp
.cfi_def_cfa_offset 16
call *f1@GOTPCREL(%rip)
leaq f3(%rip), %rax
call *%rax
addq $8, %rsp
.cfi_def_cfa_offset 8
jmp *f1@GOTPCREL(%rip)
.cfi_endproc
Since it is OK to indirect call via memory for -mforce-indirect-call,
allow indirect branch via GOT.

via GOT.
