[Qemu-devel] [PATCH] tcg/arm: Remove unused tcg_out_addi()

[Peter Maydell <peter.maydell@linaro.org>]

Remove the unused function tcg_out_addi() from the ARM TCG backend;
this fixes a compilation failure on ARM hosts with newer gcc.

A previous patch from Richard Henderson for this compile failure:
 http://patchwork.ozlabs.org/patch/110400/
was rejected, so here's another go. This simply removes the unused function,
in line with the approach taken for ppc/ppc64 in commits 1a2eb162414 and
c24a9c6ef94.

If this is accepted I can do the equivalent patches for tcg/ia64 and tcg/s390
(although those don't cause compile failures because the unused function
happens to be marked 'inline'.)
