2011-11-13Rename SlotIndexes to match how they are used.Jakob Stoklund Olesen
The old naming scheme (load/use/def/store) can be traced back to an old linear scan article, but the names don't match how slots are actually used. The load and store slots are not needed after the deferred spill code insertion framework was deleted. The use and def slots don't make any sense because we are using half-open intervals as is customary in C code, but the names suggest closed intervals. In reality, these slots were used to distinguish early-clobber defs from normal defs. The new naming scheme also has 4 slots, but the names match how the slots are really used. This is a purely mechanical renaming, but some of the code makes a lot more sense now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144503 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-16Add TargetRegisterInfo::getRawAllocationOrder().Jakob Stoklund Olesen
This virtual function will replace allocation_order_begin/end as the one to override when implementing custom allocation orders. It is simpler to have one function return an ArrayRef than having two virtual functions computing different ends of the same array. Use getRawAllocationOrder() in place of allocation_order_begin() where it makes sense, but leave some clients that look like they really want the filtered allocation orders from RegisterClassInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133170 91177308-0d34-0410-b5e6-96231b3b80d8

(gcc-4.6 warning). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117022 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12Begin adding static dependence information to passes, which will allow us toOwen Anderson
perform initialization without static constructors AND without explicit initialization by the client. For the moment, passes are required to initialize both their (potential) dependencies and any passes they preserve. I hope to be able to relax the latter requirement in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116334 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-02Added support for register allocators to record which intervals are spill ↵Lang Hames
intervals, and where the uses and defs of the original intervals were in the original code. Spill intervals can be hidden using the "-rmf-intervals=virt-nospills*" option. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112811 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-20Oops - I tables render poorly in Chrome without this explicit height ↵Lang Hames
specification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108824 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Use run-length encoding to represent identical adjacent cells in the pressureLang Hames
and interval table. Reduces output HTML file sizes by ~80% in my test cases. Also fix access of private member type by << operator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108823 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Added support for turning HTML indentation on and off (indentation off by ↵Lang Hames
default). Reduces output file size ~20% on my test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108822 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Switched to rendering after allocation (but before rewriting) in PBQP.Lang Hames
Updated renderer to use allocation information from VirtRegMap (if available) to render spilled intervals differently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108815 91177308-0d34-0410-b5e6-96231b3b80d8
