2009-03-10tcg-arm: fix qemu_ld64aurel32
Emulating fldl on arm doesn't seem to work too well. It's the way qemu_ld64 is translated to arm instructions. tcg_out_ld32_12(s, COND_AL, data_reg, addr_reg, 0); tcg_out_ld32_12(s, COND_AL, data_reg2, addr_reg, 4); Consider case where data_reg==0, data_reg2==1, and addr_reg==0. First load overwrited addr_reg. So let's put an if (data_ref==addr_reg). (Pablo Virolainen) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6808 c046a42c-6fe2-441c-8c8c-71466251a162

2008-12-13TCG x86/x86-64: use move with zero-extend for loads/storesaurel32
Starting with version 4.3, gcc returns the result of a function in rax/eax/ax/al instead of rax/eax, depending of the return type. As a consequence we should use a zero extend moe in TCG loads/stores. See http://gcc.gnu.org/ml/gcc/2008-01/msg00052.html for more details.
