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
2004-02-16memset and bcopy and now unified by the llvm.memset intrinsicChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11503 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
2004-02-13Restructure code to handle memcpy/memmoveChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11374 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

2003-11-25Do not depend on index type to determine whether it is a structure or ↵Chris Lattner
sequential index git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10221 91177308-0d34-0410-b5e6-96231b3b80d8
2003-11-14Implement a small optimization to handling of GEP's that are equivalent to ↵Chris Lattner
casts. This results in substantially reduced collapsing for some testcases git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10002 91177308-0d34-0410-b5e6-96231b3b80d8

2003-11-08Handle bzero and memset in the local analysis, because we were missing the factChris Lattner
that memset returns its argument!! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9811 91177308-0d34-0410-b5e6-96231b3b80d8
2003-11-02All DSGraphs keep a reference to the targetdata they are created with. This isChris Lattner
used to eliminate the hard coded, hacked in, sparc specific, global TargetData. Changing the TargetData used to actually match the code fixes problems, and eliminates a crash. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9659 91177308-0d34-0410-b5e6-96231b3b80d8
