Each of these instructions may have a RegsClobberInsn entry that can't be
ignored. Consecutive ranges are coalesced later when DwarfDebug::emitDebugLoc
merges entries.

The register allocator needs to know when the range shrinks.

Empty ranges may represent undef values.

A global variable with internal linkage where all uses are in one function and whose address is never taken is a non-escaping local object and can't alias anything else.

I'm tired of doing this manually for each checkout.
If anyone knows a better way debug isel for non-trivial tests feel
free to revert and let me know how to do it.

attributes. These are requires for the new 'availability' attribute.

This will extend the ranges of debug info variables in registers until they are
clobbered.

Fix 1: Don't mistake DBG_VALUE instructions referring to incoming arguments on
the stack with DBG_VALUE instructions referring to variables in the frame
pointer. This fixes the gdb test-suite failure.

Fix 2: Don't trace through copies to physical registers setting up call
arguments. These registers are call clobbered, and the source register is more
likely to be a callee-saved register that can be extended through the call
instruction.

VFP Load/Store Multiple Instructions used to embed the IA/DB addressing mode within the
MC instruction; that has been changed so that now, for example, VSTMDDB_UPD and VSTMDIA_UPD
are two instructions.  Update the ARMDisassemblerCore.cpp's DisassembleVFPLdStMulFrm()
to reflect the change.

Also add a test case.

Support argument passing simple, common, prototypes directly. More
complicated scenarios will require building up a stub function, which the
MC-JIT isn't set up to handle yet.

Add Intercept.cpp, which is just a copy from ExecutionEngine/JIT for now,
to handle looking looking up external symbol names. This probably more
properly belongs as part of RuntimeDyld. It'll migrate there as things
flesh out more fully.

Properly initialize all fields in CrashReporterCleanupContext.  This caused the buildbot failure earlier.

Now we can remove RuntimeDyld from the LLVM_LINK_COMPONENTS of
tools/lli. CMakeLists.txt LLVM_LINK_COMPONENTS shall not differ from
its companion Makefile LINK_COMPONENTS.

Temporarily stop recovering resources in CrashRecoveryContext while I investigate further why this works on my machine and not on others.

llvm-svn: 128065

Rework CrashRecoveryContextCleanup to provide a simpler way to create cleanup objects, and provide a new cleanup for
decrementing reference counts of objects with intrusive reference counts.
