* Extend the inline cost calculation to account for bonuses due toChandler Carruth2012-03-145-16/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | correlated pairs of pointer arguments at the callsite. This is designed to recognize the common C++ idiom of begin/end pointer pairs when the end pointer is a constant offset from the begin pointer. With the C-based idiom of a pointer and size, the inline cost saw the constant size calculation, and this provides the same level of information for begin/end pairs. In order to propagate this information we have to search for candidate operations on a pair of pointer function arguments (or derived from them) which would be simplified if the pointers had a known constant offset. Then the callsite analysis looks for such pointer pairs in the argument list, and applies the appropriate bonus. This helps LLVM detect that half of bounds-checked STL algorithms (such as hash_combine_range, and some hybrid sort implementations) disappear when inlined with a constant size input. However, it's not a complete fix due the inaccuracy of our cost metric for constants in general. I'm looking into that next. Benchmarks showed no significant code size change, and very minor performance changes. However, specific code such as hashing is showing significantly cleaner inlining decisions. llvm-svn: 152752

* Fixes the MSVC build.Francois Pichet2012-03-141-4/+0
| | | | | | | | | | | | | | | Commit r152704 exposed a latent MSVC limitation (aka bug). Both ilist and and iplist contains the same function: template<class InIt> void insert(iterator where, InIt first, InIt last) { for (; first != last; ++first) insert(where, *first); } Also ilist inherits from iplist and ilist contains a "using iplist<NodeTy>::insert". MSVC doesn't know which one to pick and complain with an error. I think it is safe to delete ilist::insert since it is redundant anyway. llvm-svn: 152746
* Change where we enable the heuristic that delays inlining into functionsChandler Carruth2012-03-141-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | which are small enough to themselves be inlined. Delaying in this manner can be harmful if the function is inelligible for inlining in some (or many) contexts as it pessimizes the code of the function itself in the event that inlining does not eventually happen. Previously the check was written to only do this delaying of inlining for static functions in the hope that they could be entirely deleted and in the knowledge that all callers of static functions will have the opportunity to inline if it is in fact profitable. However, with C++ we get two other important sources of functions where the definition is always available for inlining: inline functions and templated functions. This patch generalizes the inliner to allow linkonce-ODR (the linkage such C++ routines receive) to also qualify for this delay-based inlining. Benchmarking across a range of large real-world applications shows roughly 2% size increase across the board, but an average speedup of about 0.5%. Some benhcmarks improved over 2%, and the 'clang' binary itself (when bootstrapped with this feature) shows a 1% -O0 performance improvement when run over all Sema, Lex, and Parse source code smashed into a single file. A clean re-build of Clang+LLVM with a bootstrapped Clang shows approximately 2% improvement, but that measurement is often noisy. llvm-svn: 152737

* misched: implemented a framework for top-down or bottom-up scheduling.Andrew Trick2012-03-144-103/+282
| | | | | | | | | | | | | | | | | | | New flags: -misched-topdown, -misched-bottomup. They can be used with the default scheduler or with -misched=shuffle. Without either topdown/bottomup flag -misched=shuffle now alternates scheduling direction. LiveIntervals update is unimplemented with bottom-up scheduling, so only -misched-topdown currently works. Capped the ScheduleDAG hierarchy with a concrete ScheduleDAGMI class. ScheduleDAGMI is aware of the top and bottom of the unscheduled zone within the current region. Scheduling policy can be plugged into the ScheduleDAGMI driver by implementing MachineSchedStrategy. ConvergingScheduler is now the default scheduling algorithm. It exercises the new driver but still does no reordering. llvm-svn: 152700
