<pre>I've put in a fix that has been committed upstream.
ldr rt, =expr will be transformed into mov rt, expr when expr can be evaluated
to a constant and the operands can be represented by an available mov
instruction.
It does not support fixups so if expr can't be evaluated to a constant at the
time ldr rt, =expr is encountered, but can be later in the file then a constant
pool will still be generated.
