--- Comment #3 from Fangrui Song <[email protected]> ---
In principle the compiler can use GOT in -fno-pic mode. It is even desired to
do so for undefined symbols. For defined symbols, omitting GOT whenever
possible is fine.
@arr = common dso_local global [8 x i8] zeroinitializer
=>
movabsq $arr, %rdi
@arr = common dso_preemptable global [8 x i8] zeroinitializer
=>
movq arr@GOTPCREL(%rip), %rdi
Clang correctly sets dso_local/dso_preemptable. If your frontend wants to use
absolute relocations, please set dso_local explicitly.
