2004-02-27Only clone global nodes between graphs if both graphs have the global.Chris Lattner

2004-02-27ADD MORE FUNCTIONS!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11927 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-26Be a good little compiler and handle direct calls efficiently, even if thereChris Lattner
are beastly ConstantPointerRefs in the way... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11883 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-26The node doesn't have to be _no_ node flags, it just has to be complete andChris Lattner
not have any globals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11863 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-26Add _more_ functionsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11862 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-25Two changes:Chris Lattner
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11852 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-25When building local graphs, clone the initializer for constant globals into eachChris Lattner
local graph that uses the global. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11850 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-25Simplify the dead node elimination stuffChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11848 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-25Add a bunch more functionsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11847 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-25Try harder to get symbol infoChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11846 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-25Add a bunch more functions used by perlbmkChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11824 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-24Add support for 'rename'Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11813 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-24Add support for remove, fwrite, and freadChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11810 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-22Use isNull instead of getNode() to test for existence of a node, this is ↵Chris Lattner
cheaper. FIX MAJOR BUG, whereby we didn't merge null edges correctly. Correcting this fixes poolallocation on 175.vpr, and possibly others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11695 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-21Fix an iterator invalidation problem which was causing some nodes to not beChris Lattner
correctly merged over! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11693 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-21Use handy methodChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11692 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-21Instead of cloning the globals for main into the globals graph at the end ofChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11686 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-20There is no need to merge the globals graph into the function graphs at theChris Lattner
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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11684 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-20Add two missing returns, which caused us to be very pessimistic about theChris Lattner
printf and scanf families! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11683 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-20Add support for some string functions, the scanf family, and sprintfChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11673 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-17When we complete the bottom-up pass, make sure to merge the globals in ↵Chris Lattner
'main' into the globals graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11562 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-16Only spit out warning for functions that take pointers, not for sin and the likeChris Lattner
Add more special case handling for stdio functions. I feel dirty, how about you? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11506 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-15No need to scan zero initializers. This should make DSA a bit faster.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11471 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Add support for a bunch more functionsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11395 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-13Add support for fopen/fclose. Specifically with fopen, we were marking all ↵Chris Lattner
of the operands as incomplete, though fopen is known to only read them. This just adds fclose for symmetry, though it doesn't gain anything. This makes the dsgraphs for 181.mcf much more precise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11390 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11374 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-09Adjust to the changed StructType interface. In particular, ↵Chris Lattner
getElementTypes() is gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11228 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-08Add one that I missedChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11179 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-08Instead of callign removeTriviallyDeadNodes on the global graph every timeChris Lattner
removeDeadNodes is called, only call it at the end of the pass being run. This saves 1.3 seconds running DSA on 177.mesa (5.3->4.0s), which is pretty big. This is only possible because of the automatic garbage collection done on forwarding nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11178 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-08This call is no longer needed now that merging does not produce garbageChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11176 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-08Substantially improve the DSA code by removing 'forwarding' nodes fromChris Lattner
DSGraphs while they are forwarding. When the last reference to the forwarding node is dropped, the forwarding node is autodeleted. This should simplify removeTriviallyDead nodes, and is only (efficiently) possible because we are using an ilist of dsnodes now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11175 91177308-0d34-0410-b5e6-96231b3b80d8
