2011-07-18indvars: LinearFunctionTestReplace for non-canonical IVs.Andrew Trick
For -disable-iv-rewrite, perform LFTR without generating a new "canonical" induction variable. Instead find the "best" existing induction variable for use in the loop exit test and compute the final value of that IV for use in the new loop exit test. In short, convert to a simple eq/ne exit test as long as it's cheap to do so. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135420 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-18indvars: Added isHighCostExpansion. Avoid generating extra ops in theAndrew Trick
preheader for the sole purpose of LFTR, since LFTR itself is usually not a clear optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135409 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-15Disable loop idiom recognition of memset/memcpy if the function being compiledChad Rosier
is named after a common idiom (i.e., memset/memcpy). Otherwise, we can run into infinite recursion. Ideally, the user should use the correct -fno-builtin flag, but in case they don't we should play nicely. rdar://9763412 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135286 91177308-0d34-0410-b5e6-96231b3b80d8

an MDNode. This saves a bunch of time and memory in the IR linker, e.g. when doing LTO of files with debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135172 91177308-0d34-0410-b5e6-96231b3b80d8
