When we are in the label cc_dword_align, registers %o0 and %o1 have the same last 2 bits, but it's not guaranteed one of them is zero. So we can get unaligned memory access in label ccte. Example of parameters which lead to this: %o0=0x7ff183e9, %o1=0x8e709e7d, %g1=3 With the parameters I had a memory corruption, when the additional 5 bytes were rewritten. This patch corrects the error. One comment to the patch. We don't care about the third bit in %o1, because cc_end_cruft stores word or less.
