magic to converts scripts, since that is now handled
by genscripts.sh and the *.sc-sh scipt generators.
* config.h: Remove a bunch of macros defining emulations
and targets. This becomes one less file to edit when
adding emulations or targets.
* ldemul.h (struct ld_emulation_xfer_struct): Add
emulation_name and target_name fields.
* ldemul.c, ldemul.h: Define some default functions used
by most emulations (and remove from the *.em scripts).
* ldemul.c (ldemul_choose_target): Search the new
ld_emulations array using a loop (instead of a hardwired
nested if statement).
Define the ld_emulation from the automatically-geenrated
ldemul-list.h. This means you no longer have to edit ldemul.c
to add a new emulation.
* ldmain.c: Replace {GLD,LNK}960_EMULATION_NAME by
their expansions, since the former no longer exist.
* PORTING: A very rough first draft of a porting guide.
to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
* config/mh-foo: Rename LDEMULATION names as appropriate
(usually 'gldfoo' -> plain 'foo').
is to use shell scripts to generate everything.
* Each emulation is defined by a short shell script with
extension *.sh that specifies the emulation-specific
parameters (such as the name of the *.sh-sc and *.em
files to use).
* genscript.sh is the master shell script used to generate
an emulation. It is passed various argument, including
the name a the emulation-speciic *.sh file that it
"sources" to set variables to emulation-specifc parameters.
is to use shell scripts to generate everything.
* generic.em replaces ldtemplate.
* Other *.em files replace various *.c files.
A *.em file is a shell script that generates the corresponding
ld__*.c file that implements an emulation. This is usually
a straight 'cat' of a here-document, possibly with substitutions.
* Script files (*.sc) are places by *.sc-sh scripts.
Again, these are simple shell scripts that 'cat'
here-documents, usually with some substitutions.
The output a *.sc-sh is a script file.
* ldmain.c: quit using exit
* *.sc: use *(COMMON) rather than [COMMON]
* ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
to allow preprocessing of .l file.
* Makefile.in: New ldlex.l mangling
* ldexp.c (fold_binary): perform expressions with % and / in
integer.
* ldfile.c (open_a): open archives on VMS in a special way
* lderror.c: forgot to check in from a long while ago
to be "-".
* ldsym.c, ldlang.c: remember that size of a section is dependent on
whether or not relaxing has been done.
* ldmain.c: don't open a map file if it doesn't have a name
* relax.c: all the brains have moved into bfd.
* ldwrite.c: ammend comment
(2) restructure machine dependencies into separate chapter
(3) replace pretty, but quick to become obsolete, graph of BFD platforms
vs architectures with extended excerpt from (and ref to ) objdump -i.
* ldfile.c: include ctype.h
* ldmain.c: include the requried prototype headers
* ldwrite.c: get_reloc_upper_bound has been renamed
bfd_get_reloc_upper_bound
* Makefile.in: punt "fundamental" mode because it breaks my emacs
macros. install using INSTALL_PROGRAM and INSTALL_DATA. remove
spaces following hyphens, bsd make can't cope. added
standards.text support and made it look like all the other
makefiles.
* configure.in: configure now runs entirely in objdir so make file
existence checks against ${srcdir}. Mark this directory as
target dependent.

* Makefile.in: idestdir and ddestdir go away. Added copyrights
and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
and mandir now keyed off datadir by default.
