2014-04-16tcg-aarch64: Use tcg_out_mov in preference to tcg_out_movrRichard Henderson1-9/+7
It's the more canonical interface. Reviewed-by: Claudio Fontana <claudio.fontana@huawei.com> Signed-off-by: Richard Henderson <rth@twiddle.net>
2014-04-16tcg-aarch64: Prefer unsigned offsets before signed offsets for ldstRichard Henderson1-5/+6
The assembler seems to prefer them, perhaps we should too. Reviewed-by: Claudio Fontana <claudio.fontana@huawei.com> Signed-off-by: Richard Henderson <rth@twiddle.net>
2014-04-16tcg-aarch64: Introduce tcg_out_insn_3312, _3310, _3313Richard Henderson1-87/+89
Replace aarch64_ldst_op_data with AArch64LdstType, as it wasn't encoded for the proper shift for the field and was confusing. Merge aarch64_ldst_op_data, AArch64LdstType, and a few stray opcode bits into a single I3312_* argument, eliminating some magic numbers from the helper functions.

2014-03-27tcg-arm: Avoid ldrd/strd for user-only emulationRichard Henderson1-4/+17
The arm ldrd/strd insns must cause alignment traps, whereas at least for armv7 ldr/str must handle unaligned operations. While this is hardly the only problem facing user-only emu, this solves one problem for i386 on armv7 emulation.
