Are you sure? At the moment with PAC we get:
patch_pc at address 0x0000fffff58edf98 [0x0068ffffed17b5fc ->
0x00abffffed17b7f8]
With both signed and unsigned you'd have:
patch_pc at address 0x0000fffff58edf98 [0x0068ffffed17b5fc (0x0000ffffed17b5fc)
-> 0x00abffffed17b7f8 (0x0000ffffed17b7f8)]
I prefer the first - it's shorter and you can infer the address from the signed
version. Happy to go with the longer version if you think the shorter version
is confusing.
