NOTE: @ignore'd passages from earlier versions DELETED; use CVS history

gen-doc.texi, h8-doc.texi: manual configuration definitions.
Makefile.in: link config defn (`gen' by default) to configdoc.texi, included
by ld.texinfo
.Sanitize: add gen-doc.texi, h8-doc.texi
* ldindr.c (add_indirect): Keep more information in the alias
symbol chain.
* ldlang.c (wild_doit): Don't inherit NEVER_LOAD section
attribute from an input section.
* ldmain.c (Q_enter_file_symbols): Common section is NEVER_LOAD by
default. (Q_enter_file_symbos): Indirect symbols now are known by
their section, not a special symbol flag.
* ldsym.c (write_file_locals): Indirect symbols aren't local.
(write_file_globals): Write the mapping for an indirect symbol.
* relax.c (build_it): When forced to write a NEVER_LOAD section,
fill it with zeros.
specific emulation.

definition of a symbol, don't necessarily pull in an object file
that provides a non-common definition.

* Makefile.in, m68kcoff.sh, m68kcoff.sc-sh, config/m68k-coff.mt:
added m68k-coff emulation mode, stolen from a29k emulation.
Almost certainly wrong, but perhaps better than sun3.

* Makefile.in, m68kcoff.sh, m68kcoff.sc-sh, config/m68k-coff.mt:
added m68k-coff emulation mode, stolen from a29k emulation.
Almost certainly wrong, but perhaps better than sun3.
Also fixed an error message in configure.in so that it started with
'***' like the other error messages do.
gld960.em, h8300hms.em, h8300xray.em, lnk960.em, st2000.em,
vanilla.em: Rename all (generated) ld__*.c files to em_.c.
This is one character shorter, and lets people build on
SVR3 system. (ld__h8300xray.[co] was the killer there;
h8300xray.sc-sh is also overlong, but seems harmless.)
Based on a patch from Jonathan Ryshpan <hitachi!amito!jon>.
* Makefile.in (clean): Fix typo mostclean -> mostlyclean.
* configure.in: Add host isc.
abs_output_section is what is required.
* ldwrite.c (ldwrite): use malloc to allocate the largest space
used, and pass that down.
* relax.c,relax.h (write_relaxnorel): use the passed malloc area rather
than alloca.
Tue Aug 18 13:41:36 1992 Ian Lance Taylor (ian@cygnus.com)
* configure.in: accept all m68K family members.
* Makefile.in: always create installation directories.
(1) reflect current name of linker (now "ld", not "gld");
(2) fill in missing portion of a reference to full manual;
(3) fix old random typo spotted while proofing above.
chars in filenames
* ldexp.c (exp_unop): pass down abs_output_section - now can have
unary -ve constants.
* ldlang.c (lang_finish): warn when an entry symbol supplied on
the command line can't be found.
* ldlang.c (lang_output_section_statement_lookup): initilize new
field. (wild_doit): if new field is not set, then stop output
section from being loadable.
(lang_enter_output_section_statement): set the field from the
NOLOAD keyword
* ldgram.y: new synax for NOLOAD. Removes a shift/reduce too.
* h8300hms.sc-sh, h8300hms.em: get -r right.
(size_input_section): maintain the delta information.
* ldlang.h: add new field to struct to contain delta info.
* relax.c (relax_section): complain if input not relaxable.
* ldlex.l : add '_', ',' and '$' to chars which can appear at the
start of a filename
* ldexp.c: lint
* ldlang.c(open_output): set the target arch and machine as soon
as we can. (lang_size_sections): use new macros for setting vma
* ldwrite.c: lint
of YACC (since it is not longer used in the Makefile).
Remove HOSTING_* definitions that are subsumed by the
ones added to Makefile.in. Removed most definitions of CC.
* config/{sparc,news,hp300bsd,decstation}.mh: Removed;
These are no longer needed.
rules, since these are used when building a distribution.
* Makefile.in (ldlex.c): Don't re-direct output, since that
leaves a bogus output files if it fails.
* ldexp.c, ldlang.c, ldmain.c: reflect this
* ldver.c: bump version to 1.97.1
* ldindr.c (add_indirect): when an edict declaring an indirect
symbol is found, make sure that any ideas about the symbol being
common are changed if it now known to be defined.
* ldmain.c (linear_library): complain once if archive isn't
ranlibbed.
* ldlang.h, ldlang.c: make room for and initialize the complain
once field.
* ldmain.c (main): take out ./ from library path, and close file
before unlinking. Make multiple defs of a symbol create an
unexecable file.
* ldmisc.c: fatal errosrs delete output file
bfd too #.
* ldexp.c, ldlang.c: now build memory shape tree in obstacks
rather than with raw malloc, makes it easier to track where memory
is going.
* ldsym.h, ldsym.c: create obstack for all global symbols too.
* ldwrite.c (ldwrite): moved malloc so only used when needed.
* sa29200-sc.sh: added support for .lit, data1 and data2 sections.
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.

* 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
