# Check generation of .MIPS.abiflags section under the following conditions:
# - There are multiple input object files
# - Every input file has valid .MIPS.abiflags section
# - .MIPS.abiflags sections have different and incompatible FP ABI
#
# The .MIPS.abiflags section in the output file should reproduce result
# of merging FP ABI flags but the linker must show a warning.
