To: gcc-patches; +Cc: Paolo Bonzini, Richard Sandiford
Another easy part in the toplevel libgcc move was sync.c and related
stuff. While doing this, it turned out to be easier to move the rest of
gcc/config/mips/t-libgcc-mips16 rather than leave it behind.
The patch is untested except for including it in a mips-sgi-irix6.5
build to make sure it is syntactically correct, but I don't have mips16
system to actually test.
Richard, could you give it a whirl?
Ok for mainline?
Thanks.
Rainer

Since Richard had found that that patch didn't work on systems where
mips16.S is actually used since LIB1ASMSRC is only searched in
gcc/config, I'm deferring that part to a followup patch to deal with
libgcc1 (LIB1* etc.) as a whole. That patch is almost ready, just needs
a final read-over and a couple of finishing touches.
So this patch only deals with the sync functions proper and should be
relatively straightforward. Richard, could you please try this one,
too?
It is relative to the three previous patches (unwinder, fp-bit, and
soft-fp), so it might no apply cleanly for libgcc/config.host.
Ok for mainline if it passes?
Thanks.
Rainer
