--- Comment #2 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Look closer at the exact location of the error message:

$ opt -instcombine fadd.ll -S
opt: fadd.ll:2:31: error: floating point constant invalid for type
  %r = fadd float 4.500000e0, 3.200000e0
                              ^
$ opt -instcombine fadd.ll -S
opt: fadd.ll:2:19: error: floating point constant invalid for type
  %r = fadd float 3.200000e0, 3.200000e0
                  ^
The problem is not that both operands are constant. The problem is that the 3.2
constant is not representable exactly as a 'float' type; 4.5 is.
