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)? | |
