For the moment, move PRAGMA_DISABLE_PACKED_WARNING and PRAGMA_ENABLE_PACKED_WARNING back to bsd-user/qemu.h. Of course, these should be in compiler.h, but that interferes with too many things at the moment, so take one step back to unbreak clang linux-user builds first.

2023-02-17bsd-user/mmap: use TSA_NO_TSA to suppress clang TSA warnings in FreeBSDEmanuele Giuseppe Esposito1-2/+3
FreeBSD implements pthread headers using TSA (thread safety analysis) annotations, therefore when an application is compiled with -Wthread-safety there are some locking/annotation requirements that the user of the pthread API has to follow. This will also be the case in QEMU, since bsd-user/mmap.c uses the pthread API. Therefore when building it with -Wthread-safety the compiler will throw warnings because the functions are not properly annotated. We need TSA to be enabled because it ensures that the critical sections of an annotated variable are properly locked. In order to make the compiler happy and avoid adding all the necessary macros to all callers (lock functions should use TSA_ACQUIRE, while unlock TSA_RELEASE, and this applies to all users of pthread_mutex_lock and pthread_mutex_unlock), simply use TSA_NO_TSA to supppress such warnings.

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.

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).
