# REQUIRES: mips
# Conditions:
# a) Linking a non-shared executable file.
# b) Relocations' targets are symbols defined in the shared object.
# Check:
# a) Emitting R_MIPS_REL32, R_MIPS_COPY, R_MIPS_JUMP_SLOT relocations.
# b) PLT entries creation.
# c) STO_MIPS_PLT flag in the dynamic symbol table for symbols require
# a pointer equality.
