Hi Vladimir,
This patch increases code size at -Os on arm-linux-gnueabihf by 1% (with no
code-size reductions) on several SPEC CPU2006 benchmarks:
400.perlbench,perlbench_base.default ,580842,583842
429.mcf,mcf_base.default ,7867,7955
403.gcc,gcc_base.default ,1726449,1736149
433.milc,milc_base.default ,66328,66816
456.hmmer,hmmer_base.default ,148394,149434
482.sphinx3,sphinx_livepretend_base.default ,99183,99863
Could you look into whether these regressions can be avoided?
Sure, Maxim. I'll look into it. If I can not solve the problem, I probably
revert the patch.
Thanks, Vladimir. Forgot to mention that this is for Thumb2
(--target=arm-linux-gnueabihf --with-mode=thumb).
I've committed a patch which I think should solve the code size increase
problem. Could you check it, Maxim. Thanks.
