1# Create global symbol declarations, transfer vector, and
2# linker options files for PerlShr.
3#
4# Input:
5# $cflags - command line qualifiers passed to cc when preprocesing perl.h
6# Note: A rather simple-minded attempt is made to restore quotes to
7# a /Define clause - use with care.
8# $objsuffix - file type (including '.') used for object files.
748a9306
LW
9# $libperl - Perl object library.
10# $extnames - package names for static extensions (used to generate
11# linker options file entries for boot functions)
12# $rtlopt - name of options file specifying RTLs to which PerlShr.Exe
13# must be linked
a0d0e21e
LW
14#
15# Output:
16# PerlShr_Attr.Opt - linker options file which speficies that global vars
17# be placed in NOSHR,WRT psects. Use when linking any object files
18# against PerlShr.Exe, since cc places global vars in SHR,WRT psects
19# by default.
748a9306 20# PerlShr_Bld.Opt - declares universal symbols for PerlShr.Exe
a0d0e21e
LW
21# Perlshr_Gbl*.Mar, Perlshr_Gbl*.Obj (VAX only) - declares global symbols
22# for global vars (done here because gcc can't globaldef) and creates
23# transfer vectors for routines on a VAX.
24# PerlShr_Gbl.Opt (VAX only) - list of PerlShr_Gbl*.Obj, used for input
25# to the linker when building PerlShr.Exe.
26#
27# To do:
28# - figure out a good way to collect global vars in one psect, given that
29# we can't use globaldef because of gcc.
30# - then, check for existing files and preserve symbol and transfer vector
31# order for upward compatibility
32# - then, add GSMATCH to options file - but how do we insure that new
33# library has everything old one did
34# (i.e. /Define=DEBUGGING,EMBED,MULTIPLICITY)?
