2008-09-30- Initialize "--no-builtin" to "false".Bill Wendling
- Testcase for r56885. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56886 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-30Add the new `-no-builtin' flag. This flag is meant to mimic the GCCBill Wendling
`-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero" instead of "__bzero" on Darwin10+. This arguably violates the meaning of this flag, but is currently sufficient. The meaning of this flag should become more specific over time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56885 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-30Optimize SelectionDAG's AssignTopologicalOrder even further.Dan Gohman
Completely eliminate the TopOrder std::vector. Instead, sort the AllNodes list in place. This also eliminates the need to call AllNodes.size(), a linear-time operation, before performing the sort. Also, eliminate the Sources temporary std::vector, since it essentially duplicates the sorted result as it is being built. This also changes the direction of the topological sort from bottom-up to top-down. The AllNodes list starts out in roughly top-down order, so this reduces the amount of reordering needed. Top-down is also more convenient for Legalize, and ISel needed only minor adjustments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56867 91177308-0d34-0410-b5e6-96231b3b80d8
