* Implement function rewriting to use offsets instead of pointers in programs.Chris Lattner2002-04-121-217/+569
| | | | | | This now works with treeadd at least, and perhaps other programs as well. llvm-svn: 2233
* * Add documentationChris Lattner2002-04-101-210/+208
| | | | | | | | | * Split the CleanGCC pass into two passes, a global pass and an IP pass. Before it was just a global pass, but it did illegal things to the module, which broke other passes that were being scheduled with it by gccld. llvm-svn: 2224
* Implement TODO, fixing bug:Chris Lattner2002-04-091-16/+9
| | | | | | test/Regression/Transforms/LevelRaise/2002-04-09-MissedRaise.ll llvm-svn: 2219
* Move FunctionArgument out of iOther.h into Argument.h and rename class toChris Lattner2002-04-097-12/+15
| | | | | | be 'Argument' instead of FunctionArgument. llvm-svn: 2216
* Add explicit #includes of Function.h to make up for the removed #includeChris Lattner2002-04-092-0/+2
| | | | | | in iOther.h llvm-svn: 2209
* Add #includes to make up for #includes pruned out of header files.Chris Lattner2002-04-096-2/+8
| | | | llvm-svn: 2207
* s/Method/FunctionChris Lattner2002-04-0814-36/+23
| | | | | | Remove extraneous #includes of llvm/Assembly/Writer llvm-svn: 2178
* ConstantHandling moved into VMCore libraryChris Lattner2002-04-085-5/+5
| | | | llvm-svn: 2165
* Eliminate explicit use of Writer library, using debug dump output instead.Chris Lattner2002-04-071-6/+8
| | | | llvm-svn: 2147
* Change references to the Method class to be references to the FunctionChris Lattner2002-04-0714-159/+152
| | | | | | | class. The Method class is obsolete (renamed) and all references to it are being converted over to Function. llvm-svn: 2144
* s/MethodType/FunctionTypeChris Lattner2002-04-042-7/+7
| | | | llvm-svn: 2115
* PATypeHolder is now not a templateChris Lattner2002-04-041-4/+5
| | | | llvm-svn: 2106
* Allow scalars that point to multiple nodes when building the scalar map.Chris Lattner2002-04-011-5/+0
| | | | llvm-svn: 2087
* Add extra case here to avoid getting spurious outputChris Lattner2002-04-011-0/+4
| | | | llvm-svn: 2086
* Add debug outputChris Lattner2002-03-311-11/+19
| | | | llvm-svn: 2066
* * Catch and ignore (for now) return instructions in tranformed functionsChris Lattner2002-03-301-31/+58
| | | | | | | | | | | * Add more debugging output * Fix problems refering to wrong versions of various graphs * Build the pool descriptor map! * Clear the nodemapping map after building pool descriptor to avoid assert * Transform the NEw function body, not the old one... * Matrix.ll now works! llvm-svn: 2058
* * Clean up data structures [AllocDSNode -> DSNode]Chris Lattner2002-03-301-74/+232
| | | | | | | | | | | | | * TransformFunctionInfo now has call field form field mapping. May be removed in the future. * Moved the computation of "Scalars" into transformFunctionBody so transformFunction didn't have to recompute it. * Implement the node mapping calculation in preparation to calculate PoolDescriptors to pass to transformFunctionBody * Print out the node mapping [it looks right!] * Other minor changes llvm-svn: 2056
* Maintain enough information so that the pools for all of the nodes ofChris Lattner2002-03-301-44/+66

* Implement the first batch of transformations to the methods. So far it:Chris Lattner2002-03-291-2/+172
| | | | | | | | | | | * Converts malloc instructions to poolalloc * Converts free instructions to poolfree * Convert calls to call the new cloned hacked up versions Note that this does not modify hacked up stuff yet, just the top level function llvm-svn: 2052
* Correctly clone the function with the extra argument types. Now we needChris Lattner2002-03-291-6/+74
| | | | | | | | | to modify the function next. This also properly recycles functions so that we don't get exponential code blowup in the common case. llvm-svn: 2049

* Make ConvertableToGEP handle cases where the user is indexing into theChris Lattner2002-03-211-23/+29
| | | | | | | | | | | first element of a structure type. Before this would not be handled because getStructOffset would either stop immediately (because StopEarly was true and Offset = 0), or blast past the level we wanted. Now ConvertableToGEP steps down through the type one level at a time, checking the Offset and Scale conditions at each step llvm-svn: 1931
* Implement the new InsertInstBeforeInst functionChris Lattner2002-03-211-0/+14

* Fix the: test/Regression/Other/2002-03-20-LevelRaiseCrash.ll bug. It turnedChris Lattner2002-03-211-5/+24
| | | | | | | out that almost always the result of the add was the same as the GEP that would be generated. In this case, however, it wasn't, so bad things happened. llvm-svn: 1929

| | | | | | | | | | | | 2. Allow negative scales in ConvertableToGEP, so that this loop from alloc_tree in the Olden health benchmark is correctly raised: for (i = 3; i >= 0; i--) fval[i] = alloc_tree(level - 1, label*4 + i + 1, new); Stepping through the array backwards caused a negative scale. llvm-svn: 1922
