It looks so:
$ grep ' set_gdbarch_process_record ' gdb/*
amd64-linux-tdep.c: set_gdbarch_process_record (gdbarch, i386_process_record);
arm-linux-tdep.c: set_gdbarch_process_record (gdbarch, arm_process_record);
i386-linux-tdep.c: set_gdbarch_process_record (gdbarch, i386_process_record);
moxie-tdep.c: set_gdbarch_process_record (gdbarch, moxie_process_record);
But the OS dependent part seems to be missing there:
arm-tdep.h:
/* Parse swi insn args, sycall record. */
int (*arm_swi_record) (struct regcache *regcache);
- which does not seem to be set anywhere
So the current set_gdbarch_process_record initialization could be possibly
moved to arm-tdep.c. But I did not play more with it.
