| | | | | | | | | | | | | | | | | | This commit was created with scripts/clean-includes. All .c should include qemu/osdep.h first. The script performs three related cleanups: * Ensure .c files include qemu/osdep.h first. * Including it in a .h is redundant, since the .c already includes it. Drop such inclusions. * Likewise, including headers qemu/osdep.h includes is redundant. Drop these, too.

* bsd-user: introduce target.hWarner Losh2022-02-261-0/+21
| | | | | | | | | | | | | | | | Create target.h. This file is intended to be simple and describe basic things about the architecture. If something is a basic feature of the architecture, it belongs here. Should we need something that's per-BSD there will be a target-os.h that will live in the per-bsd directories. Define regpairs_aligned to reflect whether or not registers are 'paired' for 64-bit arguments or not. This will be false for all 64-bit targets, and will be true on those architectures that pair (currently just armv7 and powerpc on FreeBSD 14.x).
