Richard Osborne	54a2c32670	Handle MVT::i64 type in DAG combine for ISD::ADD. Fold 64 bit ... expression add(add(mul(x,y),a),b) -> lmul(x,y,a,b) if all operands are zero extended. llvm-svn: 98168	2010-03-10 18:12:27 +00:00
Richard Osborne	54dfa01adc	Lower add (mul a, b), c into MACCU / MACCS nodes which translate ... directly to the maccu / maccs instructions. We handle this in ExpandADDSUB since after type legalisation it is messy to recognise these operations. llvm-svn: 98150	2010-03-10 11:41:08 +00:00
Richard Osborne	e35eabdd69	Convert test to FileCheck. ... llvm-svn: 98148	2010-03-10 11:24:03 +00:00
Dan Gohman	c8054d90fb	Eliminate more uses of llvm-as and llvm-dis. ... llvm-svn: 81293	2009-09-09 00:09:15 +00:00
Richard Osborne	5fe5933909	[XCore] Fix expansion of 64 bit add/sub. Don't custom expand ... these operations if ladd/lsub are not available on the current subtarget. llvm-svn: 59305	2008-11-14 15:59:19 +00:00
