2005-03-15Fix a crash that happens when mapping something like this:Chris Lattner
{ short, short } to short where the second short maps onto the second field of the first struct. In this case, the struct index is not aligned, so we should avoid calling getLink(2), which asserts out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20626 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-30* Make some methods more const correct.Chris Lattner
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists. This makes many operations on these lists much more natural, and avoids *exteremely* expensive copying of DSCallSites (e.g. moving nodes around between lists, erasing a node from not the end of the vector, etc). With a profile build of analyze, this speeds up BU DS from 25.14s to 12.59s on 176.gcc. I expect that it would help TD even more, but I don't have data for it. This effectively eliminates removeIdenticalCalls and children from the profile, going from 6.53 to 0.27s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19939 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-30Fix three bugs:Chris Lattner
1. Calls to external global VARIABLES should not be treated as a call to an external function 2. Efficiently deleting an element from a vector by using std::swap with the back, then pop_back is NOT a good way to keep the vector sorted. 3. Our hope of having stuff get deleted by making them redundant just won't work. In particular, if we have three calls in sequence that should be merged: A, B, C first we unify B into A. To be sure that they appeared identical (so B would be erased) we set B = A. On the next step, we unified C into A and set C = A. Unfortunately, this is no guarantee that C = B, so we would fail to delete the dead call. Switch to a more explicit scheme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17357 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-30* Add a methodChris Lattner
* change some uses of NH.getNode() in a bool context to use !NH.isNull() * Fix a bunch of places where we depended on the (undefined) order of evaluation of arguments to function calls to ensure that getNode() was called before getOffset(). In practice, this was NOT happening. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17354 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-07As much as I hate to say it, the whole setNode interface for DSNodeHandlesChris Lattner
is HOPELESSLY broken. The problem is that the embedded getNode call can change the offset of the node handle in unpredictable ways. As it turns out, all of the clients of this method really want to set both the node and the offset, thus it is more efficient (and less buggy) to just do both of them in one method call. This fixes some obscure bugs handling non-forwarded node handles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14660 91177308-0d34-0410-b5e6-96231b3b80d8

2004-03-04Fix BU datastructures with povray!Chris Lattner

2004-03-03Fix a DSA bug that caused DSA to generate incredibly huge graphs and take ↵Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12104 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
