Bill Wendling da1364d669 Generate a VTBL instruction instead of a series of loads and stores when we ... can. As Nate pointed out, VTBL isn't super performant, but it *has* to be better than this: _shuf: @ BB#0: @ %entry push {r4, r7, lr} add r7, sp, #4 sub sp, #12 mov r4, sp bic r4, r4, #7 mov sp, r4 mov r2, sp vmov d16, r0, r1 orr r0, r2, #6 orr r3, r2, #7 vst1.8 {d16[0]}, [r3] vst1.8 {d16[5]}, [r0] subs r4, r7, #4 orr r0, r2, #5 vst1.8 {d16[4]}, [r0] orr r0, r2, #4 vst1.8 {d16[4]}, [r0] orr r0, r2, #3 vst1.8 {d16[0]}, [r0] orr r0, r2, #2 vst1.8 {d16[2]}, [r0] orr r0, r2, #1 vst1.8 {d16[1]}, [r0] vst1.8 {d16[3]}, [r2] vldr.64 d16, [sp] vmov r0, r1, d16 mov sp, r4 pop {r4, r7, pc} The "illegal" testcase in vext.ll is no longer illegal. <rdar://problem/9078775> llvm-svn: 127630		2011-03-14 23:02:38 +00:00
