* * Clean up the code a bitChris Lattner2002-04-161-8/+4
| | | | | | | | | * Allow structs with negative offsets. This enables the em3d benchmark to be made typesafe. In this case, the struct had an array as the first element, so a negative index was ok (the expr was -8 + 8x) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2271 91177308-0d34-0410-b5e6-96231b3b80d8

* 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1931 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1922 91177308-0d34-0410-b5e6-96231b3b80d8
