# Check that R_MIPS32 relocation against __gnu_local_gp causes emitting
# of R_MIPS_REL32 relocation in case of shared library file linking
# and does not produce any dynamic relocation in case of linking a non-shared
# executable file.

# Now the test failed because the __gnu_local_gp symbol becomes defined
# absolute symbol and we do not generate R_MIPS_REL32 in case of shared
# library linking.
# XFAIL: *
