It is common practice with powerpc to use 'rN' to refer to register 'N'. However
when using the pt_regs_offset table we have to use 'gprN'.
So add aliases such that both 'rN' and 'gprN' can be used.
For example, we can currently do:
$ su -
$ cd /sys/kernel/debug/tracing
$ echo "p:probe/sys_fchownat sys_fchownat %gpr3:s32 +0(%gpr4):string %gpr5:s32 %gpr6:s32 %gpr7:s32" > kprobe_events
$ echo 1 > events/probe/sys_fchownat/enable
$ touch /tmp/foo
$ chown root /tmp/foo
$ echo 0 > events/enable
$ cat trace
chown-2925 [014] d... 76.160657: sys_fchownat: (SyS_fchownat+0x8/0x1a0) arg1=-100 arg2="/tmp/foo" arg3=0 arg4=-1 arg5=0
Instead we'd like to be able to use:
$ echo "p:probe/sys_fchownat sys_fchownat %r3:s32 +0(%r4):string %r5:s32 %r6:s32 %r7:s32" > kprobe_events
