Arnold Schwaighofer 06413cd0f0 LoopVectorizer: Add a check that the backedge taken count + 1 does not overflow ... The loop vectorizer instantiates be-taken-count + 1 as the loop iteration count. If this expression overflows the generated code was invalid. In case of overflow the code now jumps to the scalar loop. Fixes PR17288. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209854 91177308-0d34-0410-b5e6-96231b3b80d8		2014-05-29 22:10:01 +00:00

TailCallElim	Improve 'tail' call marking in TRE. A bootstrap of clang goes from 375k calls marked tail in the IR to 470k, however this improvement does not carry into an improvement of the call/jmp ratio on x86. The most common pattern is a tail call + br to a block with nothing but a 'ret'.	2014-05-05 23:59:03 +00:00
