stor-layout.c (is_pending_size, [...]): New functions.
* stor-layout.c (is_pending_size, put_pending_size): New functions.
(variable_size): Call put_pending_size.
* tree.h (is_pending_size, put_pending_size): Add prototypes.
* fold-const.c (extract_muldiv): If SAVE_EXPR is on the pending
sizes list, put newly created SAVE_EXPR there as well.
* gcc.c-torture/execute/20010209-1.c: New test.
* config/ia64/ia64.c (last_group): Only 2 entries are needed.
(errata_find_address_regs): load_group has only 2 entries.
(errata_emit_nops): Likewise. shladd is not problematic.
Clear last_group if nop was emitted.
(fixup_errata): load_group has only 2 entries.
Optimize.
