Hi Ian, these functions should be static. It would only be a style issue except PowerPC actually #includes elf.c twice, to support both 32- and 64-bit ELF binaries. Please apply.

Unfortunately they are referenced from outside this file (xen/arch/x86/domain_build.c).

I'm not sure what a good short term fix for you would be. Perhaps some preprocessor/CFLAGS magic to name them xen_elfnote32_foo and xen_elfnote64_foo when compiling powerpc?

Hopefully long term the 32-on-64 work that is going on will lead to ELF code which doesn't need to be multiply compiled.

Why? It's simpler to compile it twice. I already posted draft patches to do this, simply introducing an elf32.c that #define-s the relevant symbols to alternative names and that only gets compiled when 64-bit arches need it for supporting 32-bit binaries.

Fair enough. I should probably have said something like "solves the problem cleanly for everyone" rather than speculating about how we would go about it ;-)

Ian.
