Hi Guys,
I am going to check in the patch below to fix a small problem with
the disassembler for the CRX target when it is running on a 64-bit
host. The EXTRACT macro was assuming that ~0L was the equivalent of
a number with 32 bits set in it, when of course this does not have
to be the case.
Discovered whilst examining crx-elf linker test results, and tested
the same way - it eliminates two unexpected failures.
Cheers
Nick
