2022-03-06target: Use ArchCPU as interface to target CPUPhilippe Mathieu-Daudé1-1/+1
ArchCPU is our interface with target-specific code. Use it as a forward-declared opaque pointer (abstract type), having its structure defined by each target.

Many files use "qemu/log.h" declarations but neglect to include it (they inherit it via "exec/exec-all.h"). "exec/exec-all.h" is a core component and shouldn't be used that way.

When a packet has 2 stores, either both commit or neither commit. At the beginning of gen_commit_packet, we check for multiple stores. If there are multiple stores, call a helper that will probe each of them before proceeding with the commit. Note that we don't call the probe helper for packets with only one store. Therefore, we call process_store_log before anything else involved in committing the packet. We also fix a typo in the comment in process_store_log.

The qemu.h file is a CONFIG_USER_ONLY header; it doesn't appear on the include path for softmmu builds. Currently we include it unconditionally in target/hexagon/op_helper.c. We used to need it for the put_user_*() and get_user_*() functions, but now that we have removed the uses of those from op_helper.c, the only reason it's still there is that we're implicitly relying on it pulling in some other headers. Explicitly include the headers we need for other functions, and drop the include of qemu.h.
