* Object: make the following changes into SymbolRefBenjamin Kramer2011-09-14
| | | | | | | | | | | - Add enum SymbolType and function getSymbolType() - Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions. - Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address. - Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.

* Distinguish complex mapped values from forced recomputation.Jakob Stoklund Olesen2011-09-13
| | | | | | | | | | | | | | | | | | When a ParentVNI maps to multiple defs in a new interval, its live range may still be derived directly from RegAssign by transferValues(). On the other hand, when instructions have been rematerialized or hoisted, it may be necessary to completely recompute live ranges using LiveRangeCalc::extend() to all uses. Use a bit in the value map to indicate that a live range must be recomputed. Rename markComplexMapped() to forceRecompute(). This fixes some live range verification errors when -split-spill-mode=size hoists back-copies by recomputing source ranges when RegAssign kills can't be moved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139660 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement -split-spill-mode=size.Jakob Stoklund Olesen2011-09-13
| | | | | | | | | | Whenever the complement interval is defined by multiple copies of the same value, hoist those back-copies to the nearest common dominator. This ensures that at most one copy is inserted per value in the complement inteval, and no phi-defs are needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139651 91177308-0d34-0410-b5e6-96231b3b80d8

* Sketch out a DWARF parser.Benjamin Kramer2011-09-13
| | | | | | | | | | This introduces a new library to LLVM: libDebugInfo. It will provide debug information parsing to LLVM. Much of the design and some of the code is taken from the LLDB project. It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an object file. It can be used to write tests for DWARF input and output easily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139627 91177308-0d34-0410-b5e6-96231b3b80d8
* Add the DataExtractor utility class.Benjamin Kramer2011-09-13
| | | | | | | | | | It is an endian-aware helper that can read data from a StringRef. It will come in handy for DWARF parsing. This class is inspired by LLDB's DataExtractor, but is stripped down to the bare minimum needed for DWARF. Comes with unit tests! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139626 91177308-0d34-0410-b5e6-96231b3b80d8

* Use a separate LiveRangeCalc for the complement in spill modes.Jakob Stoklund Olesen2011-09-13
