Description Segher Boessenkool 2018-03-07 14:17:23 UTC 
Try rs6000 with -mstring for example:

$ powerpc-linux-gcc -Wall -W -O2 -S 0.c -mstring   
powerpc-linux-gcc: warning: '-mstring' is deprecated
cc1: warning: '-mstring' is deprecated


Or on another target:

$ arc-elf-gcc -Wall -W -O2 -S 0.c -mcrc
arc-elf-gcc: warning: '-mcrc' is deprecated
cc1: warning: '-mcrc' is deprecated

Confirmed with a powepc64le cross:

$ gcc -S -mstring -xc - < /dev/null
xgcc: warning: ‘-mstring’ is deprecated
cc1: warning: ‘-mstring’ is deprecated

With a native x86_64 gcc:

$ gcc -S -mpcommit -xc - < /dev/null
xgcc: warning: ‘-mpcommit’ was deprecated
cc1: warning: ‘-mpcommit’ was deprecated
