* Fix Whitespace.Michael J. Spencer2010-11-267-65/+65
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120166 91177308-0d34-0410-b5e6-96231b3b80d8
* Move tree navigation to a new Path class that doesn't have to be a template.Jakob Stoklund Olesen2010-11-262-296/+364
| | | | | | | | The path also holds a reference to the root node, and that allows important iterator accessors like start() and stop() to have no conditional code. (When the compiler is clever enough to remove it.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120165 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove explicit uses of -emit-llvm, the test infrastructure adds itDuncan Sands2010-11-254-4/+4
| | | | | | | | | automatically. Use -S with llvm-gcc rather than -c, so tests can work when llvm-gcc is really dragonegg (which can output IR with -S but not -c).

* Exploit distributive laws (eg: And distributes over Or, Mul over Add, etc) in aDuncan Sands2010-11-235-42/+144
| | | | | | | | | | | | | fairly systematic way in instcombine. Some of these cases were already dealt with, in which case I removed the existing code. The case of Add has a bunch of funky logic which covers some of this plus a few variants (considers shifts to be a form of multiplication), which I didn't touch. The simplification performed is: A*B+A*C -> A*(B+C). The improvement is to do this in cases that were not already handled [such as A*B-A*C -> A*(B-C), which was reported on the mailing list], and also to do it more often by not checking for "only one use" if "B+C" simplifies. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120024 91177308-0d34-0410-b5e6-96231b3b80d8
