Owen Anderson 3042a65e5f Remove a very old instcombine where we would turn sequences of selects into ... logical operations on the i1's driving them. This is a bad idea for every target I can think of (confirmed with micro tests on all of: x86-64, ARM, AArch64, Mips, and PowerPC) because it forces the i1 to be materialized into a general purpose register, whereas consuming it directly into a select generally allows it to exist only transiently in a predicate or flags register. Chandler ran a set of performance tests with this change, and reported no measurable change on x86-64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201275 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-12 23:54:07 +00:00
