--- Comment #6 from rth at gcc dot gnu dot org 2007-03-20 17:09 --- Spill slots *are* being aligned, else you'd see SEGV, not incorrect data. Aliasing *is* the problem: pand(%esi), %xmm0 movl$1, (%ebx) movl$2, 4(%ebx) movl$3, 8(%ebx) movl$4, 12(%ebx) movdqa %xmm0, (%esi) note the pand before the 1,2,3,4 being stored. The problem here is our choice of vector on which to base __m128i. For some reason we chose V2DImode instead of V4SImode. It's probably easiest to fix this by adding the may_alias attribute to all of the user-visible types provided by the Intel API. -- rth at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |rth at gcc dot gnu dot org |dot org | Status|UNCONFIRMED |ASSIGNED Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2007-03-20 17:09:33 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31245

--- Comment #3 from prakash at punnoor dot de 2007-03-17 16:51 --- Sorry, I uploaded the wrong test case. In fact changing the unaligned load to aligned load triggers the bug, which the new file represents in a shorter notation, I guess. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31245
