the --enable-gold=both option is already in current binutils trunk, which will 
soon be released as binutils-2.21.  Should this be changed before the binutils 
release, or should the binutils patch be kept as it is?  Any recommendations how 
to update the patch and/or current binutils?

thanks, Matthias

We should really make the 2.21 release support --with-default-linker=
Would you care to submit a patch for this ?

to summarize:

- in binutils, --with-default-linker= should trigger which linker is
   built, and should determine which linker the ld symlink points to.

- if both linkers are built, the non-default linker build has to be
   enabled with either --enable-ld or --enable-gold.

- values (other than yes or no) passed to --enable-ld and --enable-gold
   are ignored.

Is this the consensus?

Looks good, except that I'd use --enable-default-linker (it's an 
optional "feature", not an optional "package").

Uh, actually no.  Rereading the thread, the only point on which we had 
consensus :) was to remove the current wart of --enable-gold disabling 
--enable-ld; you're proposing to double it instead.

This was my proposal:

--disable-gold [--enable-ld]
   Build only ld.  Default option.

--enable-gold[=default] [--enable-ld]
   Build both gold and ld.  Install gold as "gold" and "ld", install ld
   as "ld.bfd".  This is different from the current behavior, in that ld
   is currently not installed at all.

--enable-gold[=default] --disable-ld
   Build only gold, which is then installed as both "gold" and "ld".

--enable-gold --enable-ld=default
   Build both gold (installed as "gold") and ld (installed as "ld").
   In other words, ld is default

--enable-gold=default --enable-ld=default
   Error.

fine with this too, but you should not change "ld.gold" to "gold".

Fine with me to implement this, if there is consensus, but it won't be before 
next week.

Whatever you end up implementing, it needs updates to gcc/doc.

I'd say that binutils/README and binutils/doc/binutils.texi could also
benefit from seeing information about gold and these switches, but I'm
not sure about the usual policy here.

The attached patch implements this proposal, tested the combinations above, and 
disabling ld without gold (leading to an error).

I did choose to always install the bfd linker as ld.bfd and the gold linker as 
ld.gold, and pointing the link to one of the above.

Nick, is this ok with you?

If you test for x${ENABLE_GOLD} = xdefault, the default_ld variable can 
go away.

I think this is not necessary, you can disable both packages.  This 
would have the same effect as --without-gnu-ld.  Please conditionalize 
the message on $use_gnu_ld != no and make it a warning rather than an error.

Ok with this fixed.

in the context of binutils, at least one linker should be built?  why not detect 
this early?

Not necessarily, if the user wants the rope.  Have you tried configuring

no. ENABLE_GOLD is set to yes in the case statement above. The error message

made it a warning. Kept the condition. Having $use_gnu_ld != no still prints the 
warning for --enable-gold --disable-ld.

Ok for the branch if you have the OK for the trunk.  Would be nice to have coherent configure options!

This change:

case "${ENABLE_LD}" in
  default)
    if test x${default_ld} != xgold; then
      AC_MSG_ERROR([either gold or ld can be the default ld])
    fi
    ;;

is wrong.  At this time, default_ld is set to gold only by --enable-gold=default
What we should test is

if test x${default_ld} != x; then

which checks that default_ld isn't set.  Also comments are wrong:

# Handle --enable-gold, --enable-ld.
# --disable-gold [--enable-ld]
#     Build only ld.  Default option.
# --enable-gold[=default] [--enable-ld]
#     Build both gold and ld.  Install gold as "ld.gold" and "ld",
#     install ld as "ld.bfd".

 --enable-gold only enables gold, not make it default unless
ld is disabled.

# --enable-gold[=default] --disable-ld
#     Build only gold, which is then installed as both "ld.gold" and "ld".
# --enable-gold --enable-ld=default
#     Build both gold (installed as "gold") and ld (installed as "ld").

gold is installed as ld.gold.  ld is also installed ld.bfd.

#     In other words, ld is default
# --enable-gold=default --enable-ld=default
#     Error.

I am checking in this patch as an obvious fix.
