it. It's been assumed up til now that it would be in its immediate
successor. However, this isn't necessarily the case. It could be in one of its
successor's successors.
Modify the code to more thoroughly check for an 'eh.selector' call in
successors. It only looks at a successor if we get there as a result of an
unconditional branch.
Testcase ObjC/exceptions-4.m in r126968.

Add new instruction context for RFE instruction.
Add several new helper functions to help emulate RFE instruction
(including CurrentModeIsPrivileged, BadMode, and CPSRWriteByInstr).

1) When we do an instantiation of the injected-class-name type,
provide a proper source location. This is just plain good hygiene.
2) When we're building a NestedNameSpecifierLoc from a CXXScopeSpec,
only return an empty NestedNameSpecifierLoc if there's no
representation.
Both problems contributed to the horrible test case in PR9390 that I
couldn't reduce down to something palatable.

among other things:
// When stopped on breakppint 1, we can get the line entry using SBFrame API
// SBFrame.GetLineEntry(). We'll get the start address for the the line entry
// with the SBAddress type, resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress() in order to get the SBSymbol.
//
// We then stop at breakpoint 2, get the SBFrame, and the the SBFunction object.
//
// The address from calling GetStartAddress() on the symbol and the function
// should point to the same address, and we also verify that.
And add one utility function disassemble(target, function_or_symbol) to lldbutil.py:
"""Disassemble the function or symbol given a target.
It returns the disassembly content in a string object.
"""
TestDisasm.py uses the disassemble() function to do disassembly on the SBSymbol, and
then the SBFunction object.

for calls to weak symbols with a definition has the appearance of working
with LLVM-generated code because weak symbol definitions are put in their
own sections.

There are probably much larger speedups to be had by renumbering locally instead
of looping over the whole function. For now, the greedy register allocator is
25% faster.
llvm-svn: 126926
This is much faster than using a pointer to a ManagedStatic object accessed with
a function call. The greedy register allocator is 5% faster overall just from
the SlotIndex default constructor savings.
llvm-svn: 126925
The SlotIndex created by the default construction does not represent a position
in the function, and it doesn't make sense to compare it to other indexes.

parameter, save the instantiated default template arguments along with
the explicitly-specified template argument list. That way, we prefer
the default template template arguments corresponding to the template
template parameter rather than those of its template template argument.
This addresses the likely direction of C++ core issue 150, and fixes
PR9353/<rdar://problem/9069136>, bringing us closer to the behavior of
EDG and GCC.

// When stopped on breakppint 1, and then 2, we can get the line entries using
// SBFrame API SBFrame.GetLineEntry(). We'll get the start addresses for the
// two line entries; with the start address (of SBAddress type), we can then
// resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress().
//
// The two symbol context should point to the same symbol, i.e., 'a' function.
Add two utility functions to lldbutil.py:
o get_stopped_threads(process, reason):
return the list of threads with the specified stop reason or an empty list if not found
o get_stopped_thread(process, reason):
return the first thread with the given stop reason or None if not found
