2016-03-11[PM] Make the AnalysisManager parameter to run methods a reference.Chandler Carruth1-4/+4
This was originally a pointer to support pass managers which didn't use AnalysisManagers. However, that doesn't realistically come up much and the complexity of supporting it doesn't really make sense. In fact, *many* parts of the pass manager were just assuming the pointer was never null already. This at least makes it much more explicit and clear. llvm-svn: 263219
2016-03-11[PM] Implement the final conclusion as to how the analysis IDs shouldChandler Carruth1-1/+1
work in the face of the limitations of DLLs and templated static variables. This requires passes that use the AnalysisBase mixin provide a static variable themselves. So as to keep their APIs clean, I've made these private and befriended the CRTP base class (which is the common practice). I've added documentation to AnalysisBase for why this is necessary and at what point we can go back to the much simpler system. This is clearly a better pattern than the extern template as it caught *numerous* places where the template magic hadn't been applied and things were "just working" but would eventually have broken mysteriously. llvm-svn: 263216

2016-02-26[PM] Introduce CRTP mixin base classes to help define passes andChandler Carruth1-2/+0
analyses in the new pass manager. These just handle really basic stuff: turning a type name into a string statically that is nice to print in logs, and getting a static unique ID for each analysis. Sadly, the format of passes in anonymous namespaces makes using their names in tests really annoying so I've customized the names of the no-op passes to keep tests sane to read. This is the first of a few simplifying refactorings for the new pass manager that should reduce boilerplate and confusion. llvm-svn: 262004

2014-01-13[PM] Split DominatorTree into a concrete analysis result object whichChandler Carruth1-1/+1
can be used by both the new pass manager and the old. This removes it from any of the virtual mess of the pass interfaces and lets it derive cleanly from the DominatorTreeBase<> template. In turn, tons of boilerplate interface can be nuked and it turns into a very straightforward extension of the base DominatorTree interface. The old analysis pass is now a simple wrapper. The names and style of this split should match the split between CallGraph and CallGraphWrapperPass. All of the users of DominatorTree have been updated to match using many of the same tricks as with CallGraph. The goal is that the common type remains the resulting DominatorTree rather than the pass. This will make subsequent work toward the new pass manager significantly easier. Also in numerous places things became cleaner because I switched from re-running the pass (!!! mid way through some other passes run!!!) to directly recomputing the domtree. llvm-svn: 199104
2014-01-09Put the functionality for printing a value to a raw_ostream as anChandler Carruth1-3/+2
operand into the Value interface just like the core print method is. That gives a more conistent organization to the IR printing interfaces -- they are all attached to the IR objects themselves. Also, update all the users. This removes the 'Writer.h' header which contained only a single function declaration. llvm-svn: 198836
2014-01-07Move the LLVM IR asm writer header files into the IR directory, as theyChandler Carruth1-1/+1
are part of the core IR library in order to support dumping and other basic functionality. Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time. Update all of the #includes to match. All of this started because I wanted to have the layering in good shape before I started adding support for printing LLVM IR using the new pass infrastructure, and commandline support for the new pass infrastructure. llvm-svn: 198688
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth1-1/+1
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
