2022-01-07bsd-user/target_os_signal.h: Move signal prototypes to target_os_ucontext.hWarner Losh1-9/+0
Switch to the CPUArchState typedef and move target-provided prototypes to target_os_ucontext.h. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
2022-01-07bsd-user/x86_64: Move functions into signal.cWarner Losh2-36/+63
Move the current inline functions into sigal.c. This will increate the flexibility of implementation in the future. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>

Fill in target_mcontext match the FreeBSD mcontext_t structure. Also define the size correctly. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>

2022-01-07bsd-user/x86_64/target_arch_signal.h: Remove target_sigcontextWarner Losh1-4/+0
In FreeBSD, sigcontext was retired in favor of ucontext/mcontext. Remove vestigial target_sigcontext. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
2022-01-07bsd-user: create a per-arch signal.c fileWarner Losh1-0/+1
Create a place-holder signal.c file for each of the architectures that are currently built. In the future, some code that's currently inlined in target_arch_signal.h will live here. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
2021-10-18bsd-user: move TARGET_MC_GET_CLEAR_RET to target_os_signal.hWarner Losh1-2/+0
Move TARGET_MC_GET_CLEAR_RET to freebsd/target_os_signal.h since it's architecture agnostic on FreeBSD.

2021-09-10bsd-user: Add target_arch_reg to describe a target's register setWarner Losh1-0/+92
target_reg_t is the normal register. target_fpreg_t is the floating point registers. target_copy_regs copies the registers out of CPU context for things like core dumps.

2021-09-10bsd-user: Add architecture specific signal tramp codeWarner Losh1-0/+29
Add a stubbed out version of setup_sigtramp. This is not yet used for x86, but is used for other architectures. This will be connected in future commits.

2021-09-10bsd-user: pull in target_arch_thread.h update target_arch_elf.hWarner Losh2-35/+43
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.

2021-05-11bsd-user: remove target_signal.h, it's unusedWarner Losh1-19/+0
Remove the target_signal.h file. None of its contents are currently used and the bsd-user fork doesn't use them (so this reduces the diffs there). Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Warner Losh <imp@bsdimp.com>
