* Clean up ill-advised or unusual header guardsMarkus Armbruster2022-05-118-24/+28
| | | | | | | | | | | | | | | | | | Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions. Macros should be ALL_CAPS. Normalize the exception. Done with scripts/clean-header-guards.pl. include/hw/xen/interface/ and tools/virtiofsd/ left alone, because these were imported from Xen and libfuse respectively.

* Clean up header guards that don't match their file nameMarkus Armbruster2022-05-111-3/+3
| | | | | | | | | | | | | Header guard symbols should match their file name to make guard collisions less likely. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

* bsd-user: introduce target.hWarner Losh2022-02-271-0/+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).

* bsd-user/x86_64/target_arch_thread.h: Assume a FreeBSD targetWarner Losh2022-02-261-3/+1Star
| | | | | | | | | | | | Since we can't run on anything else, assume for the moment that this is a FreeBSD target. In the future, we'll need to handle this properly via some include file in bsd-user/*bsd/x86_64/mumble.h. There's a number of other diffs that would be needed to make things work on OtherBSD, so it doesn't make sense to preseve this one detail today.

| | | | | | | | | | | | | | | | | | | | Update target_arch_elf.h to remove thread_init. Move its contents to target_arch_thread.h and rename to target_thread_init(). Update elfload.c to call it. Create thread_os_thread.h to hold the os specific parts of the thread and threat manipulation routines. Currently, it just includes target_arch_thread.h. target_arch_thread.h contains the at the moment unused target_thread_set_upcall which will be used in the future when creating actual thread (i386 has this stubbed, but other architectures in the bsd-user tree have real ones). FreeBSD doesn't do AT_HWCAP, so remove that code. Linux does, and this code came from there. These changes are all interrelated and could be brokend down, but seem to represent a reviewable changeset since most of the change is boiler plate.
