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.

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.

llvm-svn: 126924

IndexListEntries have unique indexes, so it is not necessary to dereference
pointers to them.

llvm-svn: 126923

llvm-svn: 126922

This speeds up the greedy register allocator by 15%.
DenseMap is not as fast as one might hope.

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.

http://llvm.org/bugs/show_bug.cgi?id=9349 I introduced a bug with the last fix and Ryuta Suzuki has corrected it.  And hopefully I committed Ryuta Suzuki's directions correctly this time.

// 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
