Fariborz Jahanian 99514b9168 block variables on lhs need be ir-gen'ed after the 
rhs when its 'forwarding' pointer may be modified 
in rhs evaluation as result of call to Block_copy.

Rafael Espindola 6a85f9b42e Avoid some uses of .uleb128. This is a small speedup and more importantly 
lets this code be used when producing assembly code for old assemblers without
uleb support.

Chandler Carruth f9e7410468 Disable -Wnon-pod-memset for now while I try to reduce the false 
positives still further.

The plan is to:

1) Create a more targeted warning for memset of memory pointing at
   a type with virtual methods or bases where a vptr would be
   overwritten.
2) Consider turning the above warning back on by default.
3) Evaluate whether any false positives in the existing warning can be
   detected and white listed in the warning implementation.
4) If #3 lowers the noise floor enough, enable the full warning in -Wall
   or -Wextra.

Comments or suggestions welcome. Even more welcome are specific test
cases which trigger the warning and shouldn't.

Johnny Chen 0f023fa4af Add the Python rich comparison methods for SBBreakpoint, where GetID() returns 
the breakpoint ID and provides the semantics needed for '==' and '!='.  And
modify LLDBIteratorTestCase.lldb_iter_2() to use '==' between two SBBreakpoint's.

llvm-svn: 130493
 2011-04-29 09:59:12 +00:00
Chandler Carruth c37485e6cb Relax the non-POD memset warning to use the less restrictive C++11 
definition of POD. Specifically, this allows certain non-aggregate
types due to their data members being private.

The representation of C++11 POD testing is pretty gross. Any suggestions
for improvements there are welcome. Especially the name
'isCXX11PODType()' seems truly unfortunate.
