| | | | | | a direct callee may have indirect callees and so may have changed. llvm-svn: 13649
* Move the stuff that fixes the size, orientation & fonts of graphs toBrian Gaeke2004-05-051-7/+2
| | | | | | | | | | | the debugging functions that call "dot". These fixed settings have various problems: for example, the fixed size that is set in the graph traits classes is not appropriate for turning the dot file into a PNG, and if TrueType font rendering is being used, the 'Courier' TrueType font may not be installed. It seems easy enough to specify these things on the command line, anyhow. llvm-svn: 13366

* Implement a FIXME, improving the efficiency of DSA on povray.Chris Lattner2004-03-041-2/+16
| | | | | | | This reduces CBU time from 145s -> 122s (debug build), reduces # allocated nodes from 129420 to 116477. llvm-svn: 12125

* Fix BU datastructures with povray!Chris Lattner2004-03-041-11/+25
| | | | | | | | The problem was that we were merging a field of a node with a value that was deleted. Thanks to bugpoint for reducing povray to a nice small 3 function example. :) llvm-svn: 12116
* Minor changes, remove some debugging code that got checked in somehow.Chris Lattner2004-03-041-7/+10
| | | | | | | Make sure to scope the NodeMap passed into cloneInto so that it doesn't point to nodes that are deleted. Add some FIXME's for future performance enhancements. llvm-svn: 12115
* Only clone nodes that are needed in the caller, don't clone ALL aux calls. ↵Chris Lattner2004-03-041-20/+48
| | | | | | | | This improves povray from having ~600K nodes and 300K call nodes to 65K nodes and 25K call nodes. llvm-svn: 12109

* Fix a DSA bug that caused DSA to generate incredibly huge graphs and take ↵Chris Lattner2004-03-031-1/+34
| | | | | | | | | | forever to do it on povray. The problem is that we were not copying globals from callees to callers unless the existed in both graphs. We should have copied them in the case where the global pointed to a node that was copied as well. llvm-svn: 12104

* Add _more_ functionsChris Lattner2004-02-261-3/+20
| | | | llvm-svn: 11862
* Two changes:Chris Lattner2004-02-251-1/+4
| | | | | | | | | | | | | 1. Functions do not make things incomplete, only variables 2. Constant global variables no longer need to be marked incomplete, because we are guaranteed that the initializer for the global will be in the graph we are hacking on now. This makes resolution of indirect calls happen a lot more in the bu pass, supports things like vtables and the C counterparts (giant constant arrays of function pointers), etc... Testcase here: test/Regression/Analysis/DSGraph/constant_globals.ll llvm-svn: 11852
* When building local graphs, clone the initializer for constant globals into eachChris Lattner2004-02-251-7/+21
| | | | | | local graph that uses the global. llvm-svn: 11850
* Simplify the dead node elimination stuffChris Lattner2004-02-251-10/+12
| | | | | | | | | | Make the incompleteness marker faster by looping directly over the globals instead of over the scalars to find the globals Fix a bug where we didn't mark a global incomplete if it didn't have any outgoing edges. This wouldn't break any current clients but is still wrong. llvm-svn: 11848
* Add a bunch more functionsChris Lattner2004-02-251-8/+55
| | | | llvm-svn: 11847

| | | | llvm-svn: 11813
* Add support for remove, fwrite, and freadChris Lattner2004-02-241-22/+53
| | | | | | | Also fix problem where we didn't check to see if a node pointer was null. Though fclose(null) doesn't make a lot of sense, 300.twolf does it. llvm-svn: 11810
* Use isNull instead of getNode() to test for existence of a node, this is ↵Chris Lattner2004-02-221-6/+11
| | | | | | | | | cheaper. FIX MAJOR BUG, whereby we didn't merge null edges correctly. Correcting this fixes poolallocation on 175.vpr, and possibly others. llvm-svn: 11695

* Instead of cloning the globals for main into the globals graph at the end ofChris Lattner2004-02-211-17/+11
| | | | | | | | | BU propagation, clone the globals into the GG of EACH FUNCTION that finishes processing! The GlobalsGraph *must* include all globals and effects from all functions in the program. Fixing this makes pool allocation work better on 175.vpr, but it still ultimately crashes. llvm-svn: 11686
* There is no need to merge the globals graph into the function graphs at theChris Lattner2004-02-202-10/+3
| | | | | | | | end of the BU and CBU passes. The globals will be marked incomplete, so it doesn't matter if they are missing some info, and merging isn't guaranteed to bring everything in anyway! llvm-svn: 11684
