* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-251-13/+14
| | | | | | | | | | - Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. llvm-svn: 77019
* Revert the ConstantInt constructors back to their 2.5 forms where possible, ↵Owen Anderson2009-07-241-1/+1
| | | | | | thanks to contexts-on-types. More to come. llvm-svn: 77011

* This started as a small change, I swear. Unfortunately, lots of things call ↵Owen Anderson2009-07-091-1/+1

| | | | llvm-svn: 74753
* Allow readonly functions to unwind exceptions. TeachDuncan Sands2009-05-061-2/+2
| | | | | | | | the optimizers about this. For example, a readonly function with no uses cannot be removed unless it is also marked nounwind. llvm-svn: 71071

| | | | llvm-svn: 67287
* If "optimize for size" attribute is set then block non-trivial loop ↵Devang Patel2009-02-031-3/+2

| | | | 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

* 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
* Put FN_NOTE_AlwaysInline and others in FnAttr namespace.Devang Patel2008-09-241-1/+1
| | | | llvm-svn: 56527
* Move FN_NOTE_AlwaysInline and other out of ParamAttrs namespace.Devang Patel2008-09-231-1/+1

* Use parameter attribute store (soon to be renamed) forDevang Patel2008-09-231-1/+1

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