Re: Binutils on arm : pls advice me how to proceed

the wrong version ?

Did you get a warning about the files not being found? If so, check that you are applying the patch in the correct directory,
or use the -p option. You can always --dry-run before applying the patch.

I also tried your patch against binutils-2.16.1 - that only produced
patch failures in one file (tc-arm.c).

Hi Pedro, Hi Danny,

Please accept my apologies in taking so long to reply to your emails. I have now had a chance to go over them and the patches that they contained and then seemed quite reasonable to me. I have applied them to my local source tree and checked to see if there were any regressions - there were not.

Unfortunately I do not have an arm-wince system at my disposal, so I cannot check that the (slightly revised) versions of the patches that I applied allow working binaries to be created, so please can I ask for your help ?

I am attaching a unified patch which I think contains all of the changes that you suggested, along with a little bit of code tidying. Please could you try applying them to a set of binutils sources (from the mainline of the CVS repository) and testing them to see if they produce working binaries ?

One thing I am quite worried about is whether partial linking will work. (ie using the "ld -r ...." file to create an object file that is an amalgam of several other object files). I suspect that there might be problems with the -8 bias to branch relocations, but without a test environment I cannot tell for sure.

Thanks very much for perserving with your work, and assuming that you can confirm that the patch works, I will be happy to check it in with the ChangeLogs below.
