* 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. From-SVN: r39663
