How is EQ in mklibgcc used?

How is EQ in mklibgcc used?

[H. J. Lu]

There are

[hjl@gnu gcc]$ grep EQ mklibgcc.in
echo 'EQ = ='
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
      dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
      dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
      dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
      dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
  dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
  dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
  dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    *'$(EQ)'*) targ="T_TARGET=$out T_TARGET" ;;
  dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`
    dir=`echo ${ml} | sed -e 's/;.*$//' -e 's/=/$(EQ)/g'`

Does anyone know how it is used?

CVS history would clearly show you the patch it came from.  Half a
minute in the mail archives would show you:
  http://gcc.gnu.org/ml/gcc-patches/2000-05/msg00623.html

Thanks.

Alexandre, mklibgcc.in has been changed since then. Do we still need
it for IRIX?

Did you actually read the e-mail mentioned above?

Nothing changed in the name of the multilib directories on Irix
AFAIK.  This has absolutely nothing to do with the way mklibgcc is
designed.  It's about the presence of `=´ in filenames, that makes
don't interpret the way we'd like them to.

I thought I did. But I am not sure now.

The current mklibgcc.in generates

stmp-dirs: force
        for d in libgcc 32 libgcc/32; do \
          if [ -d $$d ]; then true; else /bin/sh /net/gnu/export/gnu/src/gcc-3.4/gcc/gcc/mkinstalldirs $$d; fi; \
	done
	...

mabi=64/libgcc is no longer a make target. Can you tell me why this
scheme won't work for IRIX?

I don't see how this can be right for irix6, that supports 3 different
ABIs and defaults to n32.  Are we talking about the same irix?

I don't see any setting of MULTILIB_DIRNAMES in t-iris6 or any other
t-* file in gcc/config/mips used for Irix that could generate what you
get.  Do you perhaps have any local patches in your tree that change
the set of multilibs and their dir names?

I assume that HJ's quote was for a different target... the point being
that the dir name no longer appears on the left of the colon.  But
won't it for some of the intermediate objects?

The example is for Linux/x86-64. I believe IRIX should be very similar,
that is rules for libgcc directories are changed. The problem EQ tried
to work around no longer exists.

I thought I'd nailed the most common interpretation with the eventual
outcome of http://gcc.gnu.org/ml/gcc-patches/2004-03/msg00104.html .
What others did I miss?  If we just rewrite them as well, we could throw
out EQ altogether, maybe.
