2003-11-11Another cleanup patch from Joakim Tjernlund:Eric Andersen
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.
2003-11-10Strip off quotes from TARGET_ARCHEric Andersen
2003-11-08Darn. Fix compilation for soft-float, which I inadvertantlyEric Andersen
broke a couple of days ago. :-(
2003-11-08Sigh. I can't type this morning.Eric Andersen

Oops, found another ppc 8xx bug. 8xx CPUs may need this as well to work:
2003-11-08hide the wrapper in with the debian stuffEric Andersen
2003-11-08Update docs in preparation for releaseEric Andersen
2003-11-08kill mention of the wrapperEric Andersen
2003-11-08For now, disable the iconv utilityEric Andersen

> Very interesting. Do you have any suggestions for how > we could fix our powerpc shared library loader 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. Jocke # And again later writes: 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. Jocke

Dear Erik, We downloded uClibc lattest version from the CVS. Still there are some minor problems with extra/Configs/Config.e1 You have actually set ARCH_HAS_C_SYMBOL_PREFIX to NO which is not correct for our architecture. Please apply the patch that will fix the problem. Best Regards, - George P.S. Patch also removes some irritating comments we have added in the past.
2003-11-06A few debugging cleanupsEric Andersen
2003-11-06The curse of cut-n-pasteEric Andersen
2003-11-06Add some initial x86 string optimizations. These make no attempt to use niftyEric Andersen
things like mmx/3dnow/etc. These are not inline, and will therefore not be as fast as modifying the headers to use inlines (and cannot therefore do tricky things when dealing with const memory). But they should (I hope!) be faster than their generic equivalents.... More importantly, these should provide a good example for others to follow when adding arch specific optimizations. -Erik

2003-11-05Add quick hacks to create fake crti.o and crtn.o files. These architecturesEric Andersen
need to be fixed properly. I tried, but I was unable to build a cross toolchain for each of these (using stock binutils and gcc) so it is someone else's problem to fix them now.
