2009-11-30Do not point edge heads to source labelsTobias Grosser
If no destination label is available, just point to the node itself instead of pointing to some source label. Source and destination labels are not related in any way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90132 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-30Only print edgeSourceLabels if they are not emptyTobias Grosser
Graphviz can layout the graphs better if a node does not contain source ports. Therefore only print the ports if the source ports are useful, that means are not labeled with the empty string "". This patch also simplifies graphs without any edgeSourceLabels e.g. the dominance trees. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90131 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-17Following a suggestion of Daniel Dunbar, stop people passing the nameDuncan Sands
as the isSigned bool to CreateIntCast by having this resolve to a call to a private method, rather than by using a gcc attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89067 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-16Make sure that if anyone passes a name by accident for the isSignedDuncan Sands
parameter of CreateIntCast then they get an error from the compiler (or from the linker with a non-gcc compiler). Another possibility is to flip the order of the DestTy and isSigned parameters, since you should then get a compiler warning if you try to use a char* for a Type*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88913 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Fix DenseMap iterator constness.Jeffrey Yasskin
This patch forbids implicit conversion of DenseMap::const_iterator to DenseMap::iterator which was possible because DenseMapIterator inherited (publicly) from DenseMapConstIterator. Conversion the other way around is now allowed as one may expect. The template DenseMapConstIterator is removed and the template parameter IsConst which specifies whether the iterator is constant is added to DenseMapIterator. Actually IsConst parameter is not necessary since the constness can be determined from KeyT but this is not relevant to the fix and can be addressed later. Patch by Victor Zverovich! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86636 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-03Run the functionattrs pass after the inliner, and not before.Duncan Sands
This makes both logical sense (see below) and increases the number of functions marked readnone/readonly by about 1-2% in practice. The number of functions marked nocapture goes up by about 5-10%. The reason it makes sense is shown by the following example: if you run -functionattrs -inline on it, then no attributes are assigned. But if you instead run -inline -functionattrs then @f is marked readnone because the simplifications produced by the inliner eliminate the store. @x = external global i32 define void @w(i1 %b) { br i1 %b, label %write, label %return write: store i32 1, i32 *@x br label %return return: ret void } define void @f() { call void @w(i1 0) ret void } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85893 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-02now that ip sccp *really* subsumes ipcp, remove ipcp again.Chris Lattner

2009-11-01fix two strange things in the default passmgr:Chris Lattner
1. we'd run simplifycfg at the very start, even though the per function passes have already cleaned this up. 2. In the main per-function pipeline that is interlaced with inlining etc, we would do instcombine, jump threading, simplifycfg *before* doing SROA. SROA is much more likely to expose opportunities for these passes than they are for SROA, so move SRoA up earlier. also add some comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85742 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-01only run GlobalDCE at -O3 and run it late instead of early.Chris Lattner
GlobalOpt already deletes trivially dead functions/globals, so GlobalDCE only adds values for cycles of dead things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85731 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-01We currently only run ipsccp at LTO time, which is silly. It subsumesChris Lattner
ipconstprop and doesn't take much time. Just run it in its place. This adds a testcase for it, which I plan to expand to cover other "integration" cases, where we expect the optimizer to be able to eliminate various things. Due to phase order issues we've regressed in a number of areas and integration tests are the only way I see to prevent this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85729 91177308-0d34-0410-b5e6-96231b3b80d8
