And dangerous. Hard-float and soft-float are ABI incompatible, so you cannot mix and match obj files and libs compiled with those two options. They all have to be hard-float or they all have to be soft-float. Think about a function compiled with hard-float calling a soft-float libm routine. The hard-float routine will pass its args in via FP regs and the soft-float lib routine will be looking for them in the integer registers.
