[Qemu-devel] [PATCH] TCG: Fix I64-on-32bit-host temporaries

2014-01-19 Thread Alexander Graf
We have cache pools of temporaries that we can reuse later when they've already been allocated before. These cache pools differenciate between the target TCG variable type they contain. So we have one pool for I32 and one pool for I64 variables. On a 32bit system, we can't work with 64bit registe
