* Do not point edge heads to source labelsTobias Grosser2009-11-30
| | | | | | | | 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
* Only print edgeSourceLabels if they are not emptyTobias Grosser2009-11-30
| | | | | | | | | | 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

* Refactor target hook for tail duplication as requested by Chris.Bob Wilson2009-11-24
| | | | | | | | | | | | | Make tail duplication of indirect branches much more aggressive (for targets that indicate that it is profitable), based on further experience with this transformation. I compiled 3 large applications with and without this more aggressive tail duplication and measured minimal changes in code size. ("size" on Darwin seems to round the text size up to the nearest page boundary, so I can only say that any code size increase was less than one 4k page.)

* * Move stub allocation inside the JITEmitter, instead of exposing aJeffrey Yasskin2009-11-23
| | | | | | | | | | | | | | | | way for each TargetJITInfo subclass to allocate its own stubs. This means stubs aren't as exactly-sized anymore, but it lets us get rid of TargetJITInfo::emitFunctionStubAtAddr(), which lets ARM and PPC support the eager JIT, fixing http://llvm.org/PR4816. * Rename the JITEmitter's stub creation functions to describe the kind of stub they create. So far, all of them create lazy-compilation stubs, but they sometimes get used when far-call stubs are needed. Fixing http://llvm.org/PR5201 will involve fixing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89715 91177308-0d34-0410-b5e6-96231b3b80d8

* I forgot to update the prototype for LLVMBuildIntCast when correctingDuncan Sands2009-11-23
| | | | | | | | | | | | | the body to not pass the name for the isSigned parameter. However it seems that changing prototypes is a big-no-no, so here I revert the previous change and pass "true" for isSigned, meaning this always does a signed cast, which was the previous behaviour assuming the name was not NULL! Some other C function needs to be introduced for the general case of signed or unsigned casts. This hopefully unbreaks the ocaml binding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89648 91177308-0d34-0410-b5e6-96231b3b80d8
