[LLVMdev] Representing -ffast-math at the IR level
The attached patch is a first attempt at representing "-ffast-math" at the IR
level, in fact on individual floating point instructions (fadd, fsub etc). It
is done using metadata. We already have a "fpmath" metadata type which can be
used to signal that reduced precision is OK for a floating point operation, eg
%z = fmul float %x, %y, !fpmath !0
...
!0 = metadata
