Split imm16Shifted into a sext/zext form for 64-bit support. Add some patterns for immediate formation. For example, we now compile this: static unsigned long long Y; void test3() { Y = 0xF0F00F00; } into: _test3: li r2, 3840 lis r3, ha16(_Y) xoris r2, r2, 61680 std r2, lo16(_Y)(r3) blr GCC produces: _test3: li r0,0 lis r2,ha16(_Y) ori r0,r0,61680 sldi r0,r0,16 ori r0,r0,3840 std r0,lo16(_Y)(r2) blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28883 91177308-0d34-0410-b5e6-96231b3b80d8 |
