Since any non-const function can examine floating-point state, I'd expect 
significant effects on code generation.  (Whether this also applies to 
asms depends on the architecture; some architectures have a register name 
you can use in asm operands to refer to floating-point state, and in those 
cases asms reading or writing that state "should" say explicitly that they 
do so, but I don't think all architectures have such a name supported by 
GCC in asms.)
