I've dug some deeper and found arch_setup_signal_frame in kernel/
arch/x86/arch_thread.cpp:
Haiku does in fact save EDI as ._reserved_2[0] and ESI
as ._reserved_2[1].
EBP however [is] not stored as .ebp but as ._reserved_2[2].
So from my view only EBX is missing.
Any comments on this, Axel? Is the EBP thing intentional? Or can I
change arch_setup/restore_signal_frame to put EBP into .ebp and
reuse ._reserved_2[2] for EBX?
An Internet search doesn't come up with much on this.
