* starting with binutils 2.24.51.20140729, MIPS binutils warn about mixing

* hardfloat and softfloat object files. The kernel build uses soft-float by
|
|
|
|
|
* default, so we also need to pass -msoft-float along to GAS if it supports it.
|
|
|

|
* But this in turn causes assembler errors in files which access hardfloat
|
|
|
|
|
* registers. We detect if GAS supports "-msoft-float" in the Makefile and
|
|
|
|
|
* explicitly put ".set hardfloat" where floating point registers are touched.
