Hal Finkel	85f2692d2f	[CFLAA] Remove one final initializer list ... Maybe MSVC will be happy now... llvm-svn: 217000	2014-09-03 00:06:47 +00:00
Hal Finkel	1ae325f53d	[CFLAA] And even more MSVC fixes ... Remove a couple more initializer lists and constexpr dependencies. llvm-svn: 216998	2014-09-02 23:50:01 +00:00
Hal Finkel	ca616acd73	[CFLAA] More cleanup for MSVC ... Remove more initializer lists, etc. llvm-svn: 216994	2014-09-02 23:29:48 +00:00
Hal Finkel	8d1590dc4b	[CFLAA] No initializer lists for MSVC ... MSVC 2012 does not understand initializer lists; remove them. llvm-svn: 216991	2014-09-02 22:52:30 +00:00
Hal Finkel	7d7087c124	[CFLAA] constexpr -> LLVM_CONSTEXPR ... Attempt to fix the MSVC build by not using constexpr. llvm-svn: 216979	2014-09-02 22:13:00 +00:00
Hal Finkel	7529c55c02	Add a CFL Alias Analysis implementation ... This provides an implementation of CFL alias analysis (including some supporting data structures). Currently, we don't have any extremely fancy features, sans some interprocedural analysis (i.e. no field sensitivity, etc.), and we do best sitting behind BasicAA + TBAA. In such a configuration, we take ~0.6-0.8% of total compile time, and give ~7-8% NoAlias responses to queries TBAA and BasicAA couldn't answer when bootstrapping LLVM. In testing this on other projects, we've seen up to 10.5% of queries dropped by BasicAA+TBAA answered with NoAlias by this algorithm. Patch by George Burgess IV (with minor modifications by me -- mostly adapting some BasicAA tests), thanks! llvm-svn: 216970	2014-09-02 21:43:13 +00:00
