# 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_MICROMIPS_26_S1)
|
||
|
|
# 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.
