[Bug middle-end/26565] Unaligned accesses with __attribute__(packed) and memcpy

[rguenth at gcc dot gnu dot org]

------- Comment #3 from rguenth at gcc dot gnu dot org  2006-03-06 10:58 -------
We indeed lose alignment information of outdata->tv.  We start expanding

 memcpy (&outdataD.1529->tvD.1528, tpD.1530, 4) [tail call]

with

(gdb) print dest_align
$1 = 32

so, builtins.c:get_pointer_alignment returns wrong (non conservative) results.
