exposed: GAS doesn't accept "fcomip %st(1)", it requires "fcomip %st(1), %st(0)" even though st(0) is implicit in all other fp stack instructions. Fortunately, there is an alias for fcomip named "fcompi" and gas does accept the default argument for the alias (boggle!). As such, switch the canonical form of this instruction to "pi" instead of "ip". This makes the code generator and disassembler generate pi, avoiding the gas bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118356 91177308-0d34-0410-b5e6-96231b3b80d8
