2017-01-31target-ppc: Consolidate instruction decode helpersBharata B Rao1-0/+151
Move instruction decode helpers to target-ppc/internal.h so that some of these can be used from outside of translate.c. This movement also helps to get rid of some duplicate helpers from target-ppc/fpu_helper.c.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth1-0/+50
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
