## Turn on PAC entries with the -z pac-plt command line option. There are no
## warnings in this case as the choice to use PAC in PLT entries is orthogonal
## to the choice of using PAC in relocatable objects. The presence of the PAC
## .note.gnu.property is an indication of preference by the relocatable object.
## Turn on PAC entries with the -z pac-plt command line option. For files w/o
## GNU_PROPERTY_AARCH64_FEATURE_1_PAC set in GNU_PROPERTY_AARCH64_FEATURE_1_AND
## property, emit a warning.
