#
# ia64: sdata_symbolic_operand() ignores -mno-sdata for constant-pool
# symbols, so GCC keeps emitting 22-bit GPREL22 (addl @gprel(...))
# relocations for reload-spilled constant-pool addresses even when
# -mno-sdata is passed. In large -fPIC objects (e.g. Firefox/libxul on
# ia64) those pool entries end up in .data.rel.ro.local, far outside
# the +-2MB GPREL22 window, and the final link fails with:
#
#   relocation truncated to fit: GPREL22 against `.data.rel.ro.local'
#
# ia64_select_rtx_section() already honors TARGET_NO_SDATA when
# choosing where to place the pool entry; the addressing predicate
# needs to do the same so such symbols fall through to the existing
# local_symbolic_operand64 path, which emits the full 64-bit
# @gprel64 (movl+add) sequence instead (see GCC PR 60465 for the
# rationale of preferring @gprel over @ltoff for local symbols).
