Subject: [LLVMdev] Upcoming API change: FAdd, FSub, FMul


> Hello,
>
> The LLVM IR opcodes Add, Sub, and Mul have been each split into
> two.  Add, Sub, and Mul now only handle integer types, and three
> new opcodes, FAdd, FSub, and FMul now handle floating-point types.
>
> The main LLVM APIs are currently preserving backwards
> compatibility, transparently mapping integer opcodes to
> corresponding floating-point opcodes when the operands have
> floating-point types. This compatibility code will eventually be
> removed, so front-end writers should update their front-ends to
> use the new opcodes.  I've updated llvm-gcc as an example.
>
> As an aid to this process, the attached patch can be applied to a
> local LLVM tree to remove the backward-compatibility code, to
> allow front-ends to be tested.
