2011-05-27Keep this simple. Use DIType to get signness and size of a type. Based on ↵Devang Patel
size, select appropraite form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132206 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Add a parameter to the Win64 EH section getters to get a section with aCharles Davis
suffix (e.g. .xdata$myfunc). The suffix part isn't implemented yet, but I'll get to it in the next patch. Fix up all callers of the affected functions. Make them pass said suffix to the function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132205 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-27Don't sink or hoist debug info instrinsics; it isn't useful. This also ↵Eli Friedman
prevents LICM sinking from erasing debug intrinsics which don't dominate any exit block of the loop. rdar://9143943 . git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132201 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Fix the inliner to maintain the current de facto invoke semantics:John McCall
- the selector for the landing pad must provide all available information about the handlers, filters, and cleanups within that landing pad - calls to _Unwind_Resume must be converted to branches to the enclosing lpad so as to avoid re-entering the unwinder when the lpad claimed it was going to handle the exception in some way This is quite specific to libUnwind-based unwinding. In an effort to not interfere too badly with other unwinders, and with existing hacks in frontends, this only triggers on _Unwind_Resume (not _Unwind_Resume_or_Rethrow) and does nothing with selectors if it cannot find a selector call for either lpad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132200 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Delete MethodBodies that only filtered reserved registers.Jakob Stoklund Olesen
The register allocators know to filter reserved registers from the allocation orders, so we don't need all of this boilerplate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132199 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-27Assorted fixes for Win64 EH unwind info emission:Charles Davis
- Flip order of bitfields. This gets our output matching GAS. - Handle case where the end of the prolog wasn't specified. - If the resulting unwind info struct is less than 8 bytes, pad to 8 bytes. Add a test for the latter two. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132188 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-27InstCombine: Make switch folding with equality compares more aggressive by ↵Benjamin Kramer

2011-05-27Start keeping track of where the various unwind instructions are in the prolog.Charles Davis
Use them to calculate the offset inside the prolog. Emit this value when emitting the unwind codes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132177 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27Add missing break statements. Align UNWIND_INFO and RUNTIME_FUNCTION structsCharles Davis
to 4 bytes. I'm surprised no one caught the missing break statements. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132176 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-27My attempt at fixing the leak reported by the valgrind buildbots. Valgrind willCharles Davis
still report leaks, but they're spurious now. Valgrind cannot peer into std::vector objects--or any dynamic array, for that matter--because it doesn't know how big the array is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132174 91177308-0d34-0410-b5e6-96231b3b80d8
