* Add the DataExtractor utility class.Benjamin Kramer2011-09-131-0/+352
| | | | | | | | | | 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.

* Initial commit of the 'landingpad' instruction.Bill Wendling2011-08-122-0/+6
| | | | | | | | | | | | | This implements the 'landingpad' instruction. It's used to indicate that a basic block is a landing pad. There are several restrictions on its use (see LangRef.html for more detail). These restrictions allow the exception handling code to gather the information it needs in a much more sane way. This patch has the definition, implementation, C interface, parsing, and bitcode support in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137501 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | working on x86 (at least for trivial testcases); other architectures will need more work so that they actually emit the appropriate instructions for orderings stricter than 'monotonic'. (As far as I can tell, the ARM, PPC, Mips, and Alpha backends need such changes.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136457 91177308-0d34-0410-b5e6-96231b3b80d8
* LangRef and basic memory-representation/reading/writing for 'cmpxchg' andEli Friedman2011-07-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | 'atomicrmw' instructions, which allow representing all the current atomic rmw intrinsics. The allowed operands for these instructions are heavily restricted at the moment; we can probably loosen it a bit, but supporting general first-class types (where it makes sense) might get a bit complicated, given how SelectionDAG works. As an initial cut, these operations do not support specifying an alignment, but it would be possible to add if we think it's useful. Specifying an alignment lower than the natural alignment would be essentially impossible to support on anything other than x86, but specifying a greater alignment would be possible. I can't think of any useful optimizations which would use that information, but maybe someone else has ideas. Optimizer/codegen support coming soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136404 91177308-0d34-0410-b5e6-96231b3b80d8
