/* For the .pdata section, which has a special meaning on the Alpha,
we set the alignment power to 3. We correct this later in
ecoff_compute_section_file_positions. We do this hackery because
we need to know the exact unaligned size of the .pdata section in
order to set the lnnoptr field correctly. For every other
section we use an alignment power of 4; this could be made target
dependent by adding a field to ecoff_backend_data, but 4 appears
to be correct for both the MIPS and the Alpha. */
