* Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman2009-06-041-1/+1
| | | | | | | | | | | | | | | | 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
* Fix for PR4235: to build a floating-point value from integer parts, Eli Friedman2009-05-201-0/+11
| | | | | | | | | | | | | | build an integer and cast that to a float. This fixes a crash caused by trying to split an f32 into two f16's. This changes the behavior in test/CodeGen/XCore/fneg.ll because that testcase now triggers a DAGCombine which converts the fneg into an integer operation. If someone is interested, it's probably possible to tweak the test to generate an actual fneg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72162 91177308-0d34-0410-b5e6-96231b3b80d8
