* Add a new hook for providing register allocator hints more flexibly.Jakob Stoklund Olesen2012-12-032-0/+59
| | | | | | | | | | | | | | | | | | The TargetRegisterInfo::getRegAllocationHints() function is going to replace the existing mechanisms for providing target-dependent hints to the register allocator: ResolveRegAllocHint() and getRawAllocationOrder(). The new hook is more flexible because it allows the target to provide multiple preferred candidate registers for each virtual register, and it is easier to use because targets are not required to return a reference to a constant array like getRawAllocationOrder(). An optional VirtRegMap argument can be used to provide target-dependent hints that depend on the provisional assignments of other virtual registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169154 91177308-0d34-0410-b5e6-96231b3b80d8

If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first.

* Remove some buggy and apparantly unnecessary code from SROA.Chandler Carruth2012-12-031-25/+6
| | | | | | | | | | | | | | | | | | | | | | | | | The partitioning logic attempted to handle uses of an alloca with an offset starting before the alloca so long as the use had some overlap with the alloca itself. However, there was a bug where we tested '(uint64_t)Offset >= AllocSize' without first checking whether 'Offset' was positive. As a consequence, essentially every negative offset (that is, starting *before* the alloca does) would be thrown out, even if it was overlapping. The subsequent code to throw out negative offsets which were actually non-overlapping was essentially dead. The code to *handle* overlapping negative offsets was actually dead! I've just removed all of this, and taught SROA to discard any uses which start prior to the alloca from the beginning. It has the lovely property of simplifying the code. =] All the tests still pass, and in fact no new tests are needed as this is already covered by our testsuite. Fixing the code so that negative offsets work the way the comments indicate they were supposed to work causes regressions. That's how I found this. Anyways, this is all progress in the correct direction -- tightening up SROA to be maximally aggressive. Some day, I really hope to turn out-of-bounds accesses to an alloca into 'unreachable'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169120 91177308-0d34-0410-b5e6-96231b3b80d8
