Daniel Jasper	162ffcacd6	Revert @llvm.assume with operator bundles (r289755-r289757) ... This creates non-linear behavior in the inliner (see more details in r289755's commit thread). llvm-svn: 290086	2016-12-19 08:22:17 +00:00
Hal Finkel	f224db75d2	Remove the AssumptionCache ... After r289755, the AssumptionCache is no longer needed. Variables affected by assumptions are now found by using the new operand-bundle-based scheme. This new scheme is more computationally efficient, and also we need much less code... llvm-svn: 289756	2016-12-15 03:02:15 +00:00
Sean Silva	11e71061b1	Consistently use FunctionAnalysisManager ... Besides a general consistently benefit, the extra layer of indirection allows the mechanical part of https://reviews.llvm.org/D23256 that requires touching every transformation and analysis to be factored out cleanly. Thanks to David for the suggestion. llvm-svn: 278077	2016-08-09 00:28:15 +00:00
Davide Italiano	c77e3fdff4	[PM] Port LoopSimplify to the new pass manager. ... While here move simplifyLoop() function to the new header, as suggested by Chandler in the review. Differential Revision: http://reviews.llvm.org/D21404 llvm-svn: 274959	2016-07-09 03:03:01 +00:00
Hal Finkel	cf203aeadb	Rename LoopSimplify.h to LoopUtils.h ... As discussed, LoopUtils.h is a better name. llvm-svn: 182314	2013-05-20 20:46:30 +00:00
Hal Finkel	4692993a01	Expose InsertPreheaderForLoop from LoopSimplify to other passes ... Other passes, PPC counter-loop formation for example, also need to add loop preheaders outside of the regular loop simplification pass. This makes InsertPreheaderForLoop a global function so that it can be used by other passes. No functionality change intended. llvm-svn: 182299	2013-05-20 16:47:07 +00:00
