* bsd-user/arm/target_arch_cpu.h: Move EXCP_ATOMIC to match linux-userWarner Losh2022-01-281-3/+3

* bsd-user: Remove vestiges of signal queueing codeWarner Losh2022-01-282-20/+2Star
| | | | | | | | | | bsd-user was copied from linux-user at a time when it queued signals. Remove those vestiges of thse code. Retain the init function, even though it's now empty since other stuff will likely be added there. Make it static since it's not called from outside of main.c Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
* bsd-user/arm/signal.c: get_mcontext should zero vfp dataWarner Losh2022-01-281-0/+9
| | | | | | | | | | FreeBSD's get_mcontext doesn't return any vfp data. Instead, it zeros out the vfp feilds (and all the spare fields). Impelement this behavior. We're still missing the sysarch(ARM_GET_VFPCONTEXT) syscall, though. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
* bsd-user/arm/signal.c: Implement setup_sigframe_arch for armWarner Losh2022-01-281-17/+33
| | | | | | | | | | | Fix the broken context setting for arm. FreeBSD's get_mcontext does not fill in the vfp info. It's filled in in sigframe(). This corresponds to the new setup_sigframe_arch which fills in mcontext, then adjusts it to point to the vfp context in the sigframe and fills in that context as well. Add pointer to where this code is done. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
