James Molloy 9342eb300f [Thumb] Select a BIC instead of AND if the immediate can be encoded more optimally negated ... If an immediate is only used in an AND node, it is possible that the immediate can be more optimally materialized when negated. If this is the case, we can negate the immediate and use a BIC instead; int i(int a) { return a & 0xfffffeec; } Used to produce: ldr r1, [CONSTPOOL] ands r0, r1 CONSTPOOL: 0xfffffeec And now produces: movs r1, #255 adds r1, #20 ; Less costly immediate generation bics r0, r1 llvm-svn: 272251		2016-06-09 07:39:08 +00:00
