Atmn Patel	ac73b73c16	[clang] Add mustprogress and llvm.loop.mustprogress attribute deduction ... Since C++11, the C++ standard has a forward progress guarantee [intro.progress], so all such functions must have the `mustprogress` requirement. In addition, from C11 and onwards, loops without a non-zero constant conditional or no conditional are also required to make progress (C11 6.8.5p6). This patch implements these attribute deductions so they can be used by the optimization passes. Differential Revision: https://reviews.llvm.org/D86841	2020-11-04 22:03:14 -05:00

Fariborz Jahanian	cc7f008b85	c++ IRGen. In trivial cases that object is going into static ... storage and thus is implicitly zero-initialized, no need to do C++11 memory model. This patch unconditionally detects such condition and zeroinitializer's the variable. Patch has been commented on and OKed by Doug off-line. // rdar://12897704 llvm-svn: 172144	2013-01-10 23:28:43 +00:00
