2023-07-25target/sparc: Handle FPRS correctly on big-endian hostsPeter Maydell4-5/+6
In CPUSparcState we define the fprs field as uint64_t. However we then refer to it in translate.c via a TCGv_i32 which we set up with tcg_global_mem_new_ptr(). This means that on a big-endian host when the guest does something to writo te the FPRS register this value ends up in the wrong half of the uint64_t, and the QEMU C code that refers to env->fprs sees the wrong value. The effect of this is that guest code that enables the FPU crashes with spurious FPU Disabled exceptions. In particular, this is why tests/avocado/machine_sparc64_sun4u.py:Sun4uMachine.test_sparc64_sun4u times out on an s390 host. There are multiple ways we could fix this; since there are actually only three bits in the FPRS register and the code in translate.c would be a bit painful to convert to dealing with a TCGv_i64, change the type of the CPU state struct field to match what translate.c is expecting. (None of the other fields referenced by the r32[] array in sparc_tcg_init() have the wrong type.)

Setting %asi is common for e.g. memcpy and memset performing block copy and clear, so it is worth noticing this case. We must end the TB but do not need to return to the main loop.
