integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8

; This testcase checks to make sure that the assembler can handle floating
|
|
; point constants in IEEE hex format. This also checks that the disassembler,
|
|
; when presented with a FP constant that cannot be represented exactly in
|
|
; exponential form, outputs it correctly in hex format. This is a distillation
|
|
; of the bug that was causing the Olden Health benchmark to output incorrect
|
|
; results!
