             Bug #: 55415
           Summary: Early SRA produces unaligned complex types
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rth@gcc.gnu.org


While looking at PR55403 one has to wonder where the unaligned
complex long double type came from in the first place:

#0  copy_node_stat (node=0x7ffff1aeb9d8) at ../../git-master/gcc/tree.c:961
#1  0x0000000000e33162 in build_distinct_type_copy (type=0x7ffff1aeb9d8)
    at ../../git-master/gcc/tree.c:5856
#2  0x0000000000e332d5 in build_variant_type_copy (type=0x7ffff1aeb9d8)
    at ../../git-master/gcc/tree.c:5890
#3  0x0000000000e33119 in build_aligned_type (type=0x7ffff1aeb9d8, align=8)
    at ../../git-master/gcc/tree.c:5842
#4  0x0000000000a39b7d in ipa_modify_call_arguments (cs=0x7ffff11493a8, 
    stmt=0x7ffff1147428, adjustments=...)
    at ../../git-master/gcc/ipa-prop.c:2967

I'm still not quite sure why ipa_modify_call_arguments *ever* wants to
create misaligned types as function interfaces?
