* [IR] Add a dedicated FNeg IR InstructionCameron McInally2018-11-131-0/+15
| | | | | | | | | | | The IEEE-754 Standard makes it clear that fneg(x) and fsub(-0.0, x) are two different operations. The former is a bitwise operation, while the latter is an arithmetic operation. This patch creates a dedicated FNeg IR Instruction to model that behavior. Differential Revision: https://reviews.llvm.org/D53877 llvm-svn: 346774

* Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman2009-06-041-2/+2
| | | | | | | | | | | | | | | 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 llvm-svn: 72897
