2014-03-08tcg-aarch64: Remove nop from qemu_st slow pathRichard Henderson
Commit 023261ef851b22a04f6c5d76da870051031757a6 failed to remove a nop that's no longer required. Reviewed-by: Claudio Fontana <claudio.fontana@huawei.com> Signed-off-by: Richard Henderson <rth@twiddle.net>
2014-03-08tcg-aarch64: Simplify tcg_out_ldst_9 encodingRichard Henderson
At first glance the code appears to be using 1's compliment encoding, a-la AArch32. Except that the constant is "off", creating a complicated split field 2's compliment encoding. Much clearer to just use a normal mask and shift. Reviewed-by: Claudio Fontana <claudio.fontana@huawei.com> Signed-off-by: Richard Henderson <rth@twiddle.net>

2014-03-08tcg-aarch64: Change all ext variables to TCGTypeRichard Henderson
We assert that the values for _I32 and _I64 are 0 and 1 respectively. This will make a couple of functions declared by tcg.c cleaner. Reviewed-by: Claudio Fontana <claudio.fontana@huawei.com> Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-09-02exec: Split softmmu_defs.hRichard Henderson
The _cmmu helpers can be moved to exec-all.h. The helpers that are used from TCG will shortly need access to tcg_target_long so move their declarations into tcg.h. This requires minor include adjustments to all TCG backends. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>
