# REQUIRES: mips

# Conditions:
#   a) Linking a non-shared executable file.
#   b) Relocations' target is a symbol defined in the shared object.
#   c) The target symbol is referenced by both branch (R_MIPS_26)
#      and regular (R_MIPS_32) relocations.
# Check:
#   a) There should be no R_MIPS_REL32 relocation.
#   b) Linker creates a single PLT entry.
#   c) STO_MIPS_PLT flag in the dynamic symbol table for symbols require
#      a pointer equality.
