typo?
for "li/lis + oris/xoris", I interpreted it into four combinations:
li + oris, lis + oris, li + xoris,

Hi,
PR106708 constaint some constants which can be support by li/lis + oris/xoris.
For constant C:
if '(c & 0x80008000ULL) == 0x8000ULL' or say:
32(0) || 1(1) || 15(x) || 1(0) || 15(x), we could use li+oris to
build constant 'C'.
Here N(M) means N continuous bit M, x for M means it is
16 matches
