Once we've found a "good" method, we don't need to check its argument types
again. (Even if we might have later found a "bad" method, we were already
caching the method we first looked up.)

In the current implementation AsanThread::GetFrameNameByAddr scans the
stack for a magic guard value to locate base address of the stack
frame. This is not reliable, especially on ARM, where the code that
stores this magic value has to construct it in a register from two
small intermediates; this register can then end up stored in a random
stack location in the prologue of another function.

With this change, GetFrameNameByAddr scans the shadow memory for the
signature of a left stack redzone instead. It is now possible to
remove the magic from the instrumentation pass for additional
performance gain. We keep it there for now just to make sure the new
algorithm does not fail in some corner case.

Ordinary patch for PR1255.
Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object.
Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added. Old "switch" format is also supported.

Remove the piece of code in MipsFunctionInfo::getGlobalBaseReg() which returns
GP. This function should always return a virtual register.

- Stop creating stack frame objects needed for saving $gp.
- Insert a node that copies the global pointer register to register $gp
  before the call node. This will ensure $gp is valid at the entry of the
  called function.

llvm-svn: 156692

- Stop emitting instructions needed to initialize the global pointer register.
- Stop emitting .cprestore directive.
- Do not take into account the $gp save slot when computing stack size.

TableGen doesn't need to search through the SubRegs map to find an
inverse entry.

llvm-svn: 156690

- Remove code which lowers pseudo SETGP01.
- Fix LowerSETGP01. The first two of the three instructions that are emitted to
  initialize the global pointer register now use register $2.
- Stop emitting .cpload directive.

Add a useful error message to "log enable" with the wrong number of arguments, and reject "log enable lldb" which just silently did nothing before.

Empty live ranges represent undef and still get allocated, but they

"lldb -a i386" doesn't set the calculator mode correctly if run on a 64 bit system. 

The previous logic always used the current host architecture, not the default architecture. The default arch gets set into a static varaible in lldb_private::Target when an arch is set from the command line:

lldb -a i386

We now use the default arch correctly.

pointer register. 


This is the first of the series of patches which clean up the way global pointer
register is used. The patches will make the following improvements:

- Make $gp an allocatable temporary register rather than reserving it.
- Use a virtual register as the global pointer register and let the register
  allocator decide which register to assign to it or whether spill/reloads are
  needed.
- Make sure $gp is valid at the entry of a called function, which is necessary
  for functions using lazy binding.
- Remove the need for emitting .cprestore and .cpload directives.

Also changed the defaults for SBThread::Step* to not delete extant plans.
Also added some test cases to test more complex stepping scenarios.
