// The R_ARM_TARGET2 is present in .ARM.extab sections. It can be handled as
|
|
// either R_ARM_ABS32, R_ARM_REL32 or R_ARM_GOT_PREL. For ARM linux the default
|
|
// is R_ARM_GOT_PREL. The other two options are primarily used for bare-metal,
|
|
// they can be selected with the --target2=abs or --target2=rel option.
