It builds now, but parts of libgcc are missing. There's no sign of
muldf3, for examples.
I found the problem: before, LIB2ADD was passed in from gcc/config via
libgcc.mvars, and added to in t-softfp. Now the order of the t-*
fragments has been kept the same, with the assignment to LIB2ADD in
c6x/t-elf overriding what has been constructed by t-softfp before.
The following patch did the trick for me, could you give it a try?
Looks ok, but these look like they could also be broken.
Sorry it took me so long, but this weekend I finally had a close look
at both the explicit settings of LIB2ADD and LIB2FUNCS_EXCLUDE. The
latter are unproblematic since the files affected are disjunct. For
LIB2ADD, here are the problematic cases. All others explicitly setting
LIB2ADD have no issues since there are no t-* fragments setting LIB2ADD
before.
i386/t-darwin64:LIB2ADD = $(srcdir)/config/darwin-64.c
The file is currently unused, was lost in the migration for
x86_64-*-darwin*. The same settings are already in i386/t-darwin, so
the file is superfluous and can be removed.
iq2000/t-iq2000:LIB2ADD = $(srcdir)/udivmod.c \
This file is unused, now restored, otherwise no problem.
pa/t-pa64:LIB2ADD = $(srcdir)/config/pa/quadlib.c
This overrides pa/t-hpux, originally we had pa/t-pa64 pa/t-pa-hpux
without overrides, but the result is ok.
rs6000/t-darwin64:LIB2ADD = $(srcdir)/config/rs6000/darwin-tramp.S \
Overrides rs6000/t-darwin, as it did before the move.
rs6000/t-lynx:LIB2ADD = $(srcdir)/config/rs6000/tramp.S
This file is currently unused, but necessary. t-lynx is also missing,
but no settings left.
rs6000/t-netbsd:LIB2ADD = $(srcdir)/config/rs6000/tramp.S
unused, necessary
sh/t-netbsd:LIB2ADD =
The override poses no problem, but is unnecessary since nothing sets
LIB2ADD before.
t-vxworks:LIB2ADD = $(srcdir)/config/vxlib.c $(srcdir)/config/vxlib-tls.c
Ok, but missing from powerpc-wrs-vxworks which didn't add to tmake_file.
The following patch implements those observations.
Ok for mainline?
