Here's a RFC series for eliminating AREG0. Blue Swirl (11): Move user emulator stuff from cpu-exec.c to user-exec.c Delete unused tb_invalidate_page_range
The above should be OK to commit. cpu_loop_exit: avoid using AREG0 Delegate setup of TCG temporaries to targets These two are not, unless the overall plan is OK. TCG: fix negative frame offset calculations TCG/x86: use stack for TCG temps TCG/Sparc64: use stack for TCG temps But these three should be OK. I've tested lightly x86_64 and Sparc64 hosts. Add CONFIG_TARGET_NEEDS_AREG0 Don't compile legacy qemu_ld/st functions if target doesn't need them Should be OK, though the latter patch only touches x86. Add new qemu_ld and qemu_st functions sparc: use new qemu_ld and qemu_st functions The last two compile but QEMU segfaults. I just made a naive conversion for getting comments.
