# A default mapfile for optimizing the creation of a filter shared object.
# Creates a single, read-only, executable text segment to catch all loadable
# sections.
#
# Filters that consist solely of a symbol table can be built directly from
# ld(1) so that no .init/.fini sections are created.  Although the filter can
# be constructed as a single read-only segment, the execute attribute of the
# segment is maintained to allow for simple .init processing (i.e., .init
# processing that requires no relocations), and to accommodate older versions
# of dbx that produce warning messages if they find objects without traditional
# text segments.
#
# If a filter is required to execute .init code that references global data
# then the filter will require relocation (i.e., it will have to be written to
# by ld.so.1).  Filters of this sort should *not* use this mapfile.
#
# This compaction of a filter into a single segment allows ld.so.1 to optimize
# its processing of a filter.  If the filter is small enough this segment may
# be handled in a single page mapping (for example libdl.so.1).
#
# The assignment of all allocatable sections to this segment insures that the
# .dynamic, and any .data or .bss sections, become part of the text.  Note that
# the compiler has a habit of generating empty .data and .bss sections.
#
# Override the default alignment so that this single paged object can be mapped
# more flexibly.

# A number of dynamic executables have their own definitions of interfaces that
# exist in system libraries.  To prevent name-space pollution it is desirable
# to demote the interfaces within these executable to locals.  However, various
# symbols defined by the compiler drivers crt/values files need to remain
# global in any dynamic object that includes these files.  These symbols
# interpose on symbols in libc, or provide call backs for other system
# libraries.  The various compiler drivers (cc and gcc), and the crt/values
# files that these drivers are configured to include, differ between the
# various compilations environments (platform, 32/64-bit).  Therefore, the
# only means of creating a mapfile to demote symbols is to dynamically generate
# the mapfile for a specific compilation environment.
#
# Here, template mapfiles are used to generate a number of compilation specific
# mapfiles.  These mapfiles are referenced by components of the build through
# the MAPFILE.NGB macro defined in Makefile.master.  These dynamically created
# mapfiles are not delivered into the $ROOT area, and therefore are not
# delivered as packaged components of the OSNet.

# This generic target creates two dynamic executables from an empty "main"
# program.  These objects are not executed, but are analyzed to determine the
# global symbols each provides.
#
# The first executable demotes a family of known interfaces to local and allows
# all other symbol definitions to remain global.  This executables provides the
# base for discovering all symbol definitions provided by the various
# compilation environments.  The second executable demotes all symbols to
# locals.  Within both executables, some symbols remain globals (_end, _etext,
# etc.) as the link-editor has special knowledge of these symbols and their
# expected visibility requirements.  By inspecting the deferences between the
# global symbols within the two executables, a mapfile can be generated to
# ensure the symbols defined by the compilation environments files remain
# global.
