2008-12-01arm: Don't potentially overwrite input registers in add2, sub2.balrog
According to malc TCG will often genereate an add2/sub2/mul2 with low half of the output in the same register as high half of one of the inputs, so account for that. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5847 c046a42c-6fe2-441c-8c8c-71466251a162
2008-12-01Don't rely on ARM tcg_out_goto() generating just a single insn.balrog
Otherwise when tb_exit generates a jump beyond the pc-relative range, tcg_out_goto() spans two/three instructions and we load the tb return value from a wrong address. This is #ifdefed out currently because we take care for the jumps to be local. Problem spotted by Steffen Liebergeld. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5845 c046a42c-6fe2-441c-8c8c-71466251a162
2008-12-01Use libgcc __clear_cache to clean icache, when available.balrog
Calling the clear cache syscall directly generates an illegal instruction on some (armv4) kernels. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5843 c046a42c-6fe2-441c-8c8c-71466251a162

2008-11-11Fix alignment problem with some 64bit load/store instructionsmalc
LD/STD/LWA require displacement to be multiple of 4, provide tcg_out_ldsta which checks the supplied displacement and falls back on indexed variant when the check fails. All uses of LD/STD/LWA outside of tcg_out_ldst appear to be safe. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5670 c046a42c-6fe2-441c-8c8c-71466251a162
