<pre>Consider below testcase
$cat test.ll
@arr = common global [8 x i8] zeroinitializer
define void @foo() {
entry:
call void @bar(i8* getelementptr inbounds ([8 x i8], [8 x i8]* @arr, i64 0,
i64 0))
ret void
}
declare void @bar(i8*)
$./clang test.ll -c -Xassembler -mrelax-relocations=no -mno-relax-all -S
warning: overriding the module target triple with x86_64-unknown-linux-gnu
[-Woverride-module]
1 warning generated.
$ cat test.s
.text
.file "test.ll"
.globl foo # -- Begin function foo
.p2align 4, 0x90
.type foo,@function
foo: # @foo
.cfi_startproc
# %bb.0: # %entry
pushq %rax
.cfi_def_cfa_offset 16
movq arr@GOTPCREL(%rip), %rdi
callq bar@PLT
popq %rax
.cfi_def_cfa_offset 8
retq
.Lfunc_end0:
.size foo, .Lfunc_end0-foo
.cfi_endproc
# -- End function
.type arr,@object # @arr
.comm arr,8,1
.section ".note.GNU-stack","",@progbits
.addrsig
.addrsig_sym bar
.addrsig_sym arr
As can be seen above GOTPCREL is generated for non pic code.</pre>
