[parisc-linux] 64-bit kernel builds with gcc-3.4 experimental cross.

jda,

Any thoughts? This ld was from a multi-arch binutils that had
enable-targets with hppa64-linux.

As far as I know, there is no multi-arch support in ld or as.
There isn't multi-arch support in GCC either.  You need separate
compilers for 32 and 64 bits.

Separate compilers yes. Separate linker and assembler no.
I thought I could use '--enable-targets=hppa64-linux' in binutils.

There isn't an option in as to select the output object format.
There are somewhat different relocations used in the 32 and 64
bit formats.  So, I don't see how you can use a single assembler
for both.

You may be able to use "-A" with ld but GCC doesn't support this.

I think that only works for some parts of binutils -- specifically not ld.

So it seems. Fiddle sticks. Two builds it is then :)
