[LLVMdev] API change: add, sub, and mul no longer do floating-point
Quick heads up: On LLVM trunk, the add, sub, and mul instructions no longer accept floating-point operands. The fadd, fsub, and fmul instructions should be used instead. This change actually happened back in LLVM 2.6; since then, LLVM has just been silently converting add into fadd and so on, and the change today is that it no longer does this silent conversion. Dan
