* builtins.c (get_memory_rtx): Add LEN argument. If MEM_EXPR is
a COMPONENT_REF, remove all COMPONENT_REF from MEM_EXPR unless
at most LEN bytes long memory fits into the field.
(expand_builtin_memcpy, expand_builtin_mempcpy, expand_movstr,
expand_builtin_strncpy, expand_builtin_memset, expand_builtin_memcmp,
expand_builtin_strcmp, expand_builtin_strncmp): Adjust callers.
* gcc.c-torture/execute/20050826-1.c: New test.
git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@103541 138bc75d-0d04-0410-961f-82ee72b054a4
