27# Linker mapfile that enables the creation of a 'bss' segment, and aligns
28# the segment at 4Mb.  This effectively provides an appropriate alignment for
29# large page mapping of the heap, and thus can be useful when building dynamic
30# executables.  See ppgsz(1).  Users are cautioned that an alignment
31# specification may be machine-specific, and may lose its benefit on different
32# hardware platforms.  A more flexible means of requesting the most optimal
33# underlying page size may evolve in future releases.
34#
35# The linker does not use this file automatically, so one must use the -M
36# option to cc or ld:
37#
38#       cc -M /usr/lib/ld/map.bssalign myprogram.c
