On MIPS when the toolchain is using the O32 FPXX ABI, the testsuite fails to build for pre-R2 CPU. It assumes that it is possible to use the -mfp64 option to build tst-abi-fp64amod and tst-abi-fp64mod, while this requires a CPU which supports the mfhc1 and mthc1 instructions, ie at least a R2 CPU: error: '-mgp32' and '-mfp64' can only be combined if the target supports the mfhc1 and mthc1 instructions The same way it assumes that it is possible to use the -modd-spreg option to build tst-abi-fpxxomod and tst-abi-fp64mod, while this requires at least a R1 CPU: warning: the 'mips2' architecture does not support odd single-precision registers This patches changes that by checking the usability of -mfp64 and -modd-spreg options in configure, and disable those tests when they can not be used.
