* Remove strange extra semicolons.Nick Lewycky2009-03-191-1/+1
| | | | llvm-svn: 67287
* If "optimize for size" attribute is set then block non-trivial loop ↵Devang Patel2009-02-031-3/+2
| | | | | | unswitches but allow trivial loop unswitches. llvm-svn: 63670
* Rename getAnalysisToUpdate to getAnalysisIfAvailable.Duncan Sands2009-01-281-2/+2
| | | | llvm-svn: 63198
* Undo previous patch. Devang Patel2008-12-081-3/+1

| | | | llvm-svn: 60337
* Ignore conditions that are outside the loop.Devang Patel2008-11-031-2/+4
| | | | llvm-svn: 58631
* Change create*Pass factory functions to return Pass* instead ofDaniel Dunbar2008-10-221-1/+1
| | | | | | | | | | | LoopPass*. - Although less precise, this means they can be used in clients without RTTI (who would otherwise need to include LoopPass.h, which eventually includes things using dynamic_cast). This was the simplest solution that presented itself, but I am happy to use a better one if available. llvm-svn: 58010
* Use 0 instead of false to return a null pointer.Dan Gohman2008-10-171-1/+1
| | | | llvm-svn: 57660
* Implement function notes as function attributes. Devang Patel2008-09-261-1/+1
| | | | llvm-svn: 56716
* Large mechanical patch.Devang Patel2008-09-251-1/+1
| | | | | | | | | | | | | | | s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes. This requires corresponding changes in llvm-gcc and clang. llvm-svn: 56622

* Move FN_NOTE_AlwaysInline and other out of ParamAttrs namespace.Devang Patel2008-09-231-1/+1
| | | | | | Do not check isDeclaration() in hasNote(). It is clients' responsibility. llvm-svn: 56524

| | | | llvm-svn: 56477

* Initialize loop data first.Devang Patel2008-09-041-2/+1

* Do not try to update dominator info while manipulating CFG. This code does ↵Devang Patel2008-07-031-281/+19
| | | | | | | | not handle all cases and keeps invalid dom info around some cases, which misleads other passes down stream. Right now, dom info is recaluclated in the end if the loop is switched. llvm-svn: 53106

* Clean up the use of static and anonymous namespaces. This turned upDan Gohman2008-05-131-11/+11
