With old "medium" code model, we call a function with a pair of PCALAU12I and JIRL instructions. The assembler produces something like: 8: 1a00000c pcalau12i $t0, 0 8: R_LARCH_PCALA_HI20 g c: 4c000181 jirl $ra, $t0, 0 c: R_LARCH_PCALA_LO12 g The linker generates a "PLT entry" for data without any diagnostic. If "g" is a data symbol and ld with -shared option, it may load two instructions in the PLT. Without -shared option, loongarch_elf_adjust_dynamic_symbol can delete PLT entry. For R_LARCH_PCALA_HI20 relocation, linker only generate PLT entry for STT_FUNC and STT_GNU_IFUNC symbols.
