    Removing those instr. comes with a very big performance
    penalty. To flush the dcache you will have read up to 8KB
    dummy data and to invalidate the icache you will have to
    execute up to 16KB nops. I don't know of any other way from
    user space.

    hmm, actually I think it will work reliable to perform a
    store to the same page(s) as the dcbst/icbi will act on. That
    way you will make the DTLB Error happen(if any) prior to the
    dcbst/icbi. The worst thing that can happen then is a regular
    DTLB Miss and that works for dcbst/icbi.

    You will have to lookout for if dcbst/icbi crosses a page
    boundary. Then you will have to perform a store to both
    pages.

    Hi again

    I think I know what the problem is. The
    PPC_DCBST;PPC_SYNC;PPC_ICBI;PPC_ISYNC sequence is executed
    even if no modification has been done i some cases:

     _dl_linux_resolver(), the last else has no store for insns[0].
			   these is a insns[1] = OPCODE_B(delta - 4) that
			   does not have a PPC_DCBST.

     _dl_do_lazy_reloc(), for R_PPC_NONE there is no store.
			  for R_PPC_JMP_SLOT there is a
			  insns[1] = OPCODE_B(delta)that does not
			  have a PPC_DCBST.

     _dl_do_reloc(), for R_PPC_COPY there is no store.
		     for R_PPC_JMP_SLOT there is a
		     reloc_addr[1] = OPCODE_B(delta) that does not
		     have a PPC_DCBST.

     _dl_init_got(), I THINK that the
	    PPC_DCBST(plt);
	    PPC_DCBST(plt+4);
	    PPC_DCBST(plt+8);
	    PPC_SYNC;
	    PPC_ICBI(plt);
	    PPC_ICBI(plt+4);
	    PPC_ICBI(plt+8);
	    PPC_ISYNC;
	    is off a bit. The address range does not match the sum
	    of the plt[] and tramp[] address range.

       Jocke


# And then later added the comment:


    I think that the tramp[] part should be included in the
    PPC_DCBST/PPC_ICBI sequence. Then you have to add entries for
    plt+12 and plt+16. If the tramp[] part should be excluded,
    then all is well.

Hi again

Back at work. Here is a patch that fixes the 2 errors I found yesterday.
I have excluded the "data_words[index]" part for now.

Hello Erik,

to compile the new uClibc release for a SH3 we need some little
modifications:

First I fix the crt[in].S files, so we can use them for big endian and
little endian targets.

Another little patch fix the configuration for the SH3 targets. The SH3 has
no FPU, but our ldso runs fine on a SH3 target.  (I think the
ldso should also run on a SH2 target, so you might want to enable the ldso
for SH2 targets too. But I can't test it, since I have no such a system) :

Joakim Tjernlund writes:

    Comparing glibc with uClibc makes me think that the delta calculations are
    wrong here.  Comparing some more I still think there are a
    data_words[index] assignments missing. Here is a path that has both the
    data_words[index] and the above delta calclations.

This also fixes a terribly obvious bug, also spotted by Joakim, which Erik
introduced when he copied things from the i386 ldso code.

With this patch applied, things now seem to be working perfectly!

    Hi Erik

    I just saw something that might be a problem.

    The "delta" variable is signed and
    the "delta" calculations, such as delta = PLT_LONGBRANCH_ENTRY_WORDS*4 - (insn_addr-plt_addr+4),
    are supposed to be unsigned.
