The new test is also failing on IA64 HP-UX and PA HP-UX (32 and 64 bits). It
is not failing on IA64 Linux. Could the test have a big-endian/little-endian
issue?

During update_alias_info we collect the variables that are written to, but
because we use gimple_stored_syms to get at them we miss those that are in
memory partitions. If the new partitioning moves them out of a pa

At *.crited there is still a virtual dependency between a = x; (and b = b0;)
and
*srcp1 + *srcp2 reads:
# MPT.26D.2201_438 = VDEF { MPT.26D.2201 }
aD.2099 = xD.2073_296;
# MPT.26D.2201_439 = VDEF { MPT.26D.2201

*.copyprop4 still contains the needed stores:
[gg5.c : 151] D.2147_293 = a3D.2068_292 >> shlD.2074_195;
[gg5.c : 151] D.2148_295 = a0D.2065_294 << shrD.2075_198;
[gg5.c : 151] xD.2073_296 = D.2148_295 | D.2147_29

In assembly, it seems the a and b arguments to mymemcmp1 aren't stored into
memory at all:
.loc 1 128 0
movq(%rax), %r12#* srcp2.272, b0
.LVL54:
.loc 1 126 0
movq(%rdi), %rsi

Confirmed. PRE doesn't do anything interesting though, neither are the
differences in the optimized dump interesting from a first look.
