commit 55d9b4c146716a683d9fea769e5f4106eadb30fc
Author: Nick Clifton <address@hidden>
Date:   Wed Mar 12 15:44:09 2014 +0000

    The value of a bignum expression is held in a single global array.  This
means
    that if multiple bignum values are encountered only the most recent is
valid.
    If such expressions are cached, eg to be emitted into a literal pool later
on
    in the assembly, then only one expression - the last - will be correct. 
This
    patch fixes the problem for the AArch64 target by caching each bignum value
    locally.

        PR gas/16688
        * config/tc-aarch64.c (literal_expression): New structure.
        (literal_pool): Replace exp array with literal_expression array.
        (add_to_lit_pool): When adding a bignum cache the big value.
        (s_ltorg): When emitting a bignum initialise the global bignum
        array from the cached value.

        * gas/aarch64/litpool.s: New test case.
        * gas/aarch64/litpool.d: Expected disassembly.
