This is gnat.dg/pack9.ad[sb].  You need a bare cross-compiler to s390x-linux: 
configure, build with make CFLAGS=-g, when the build fails, do gcc/ada then 
make gnatlib.  Go back to the build dir, copy gnat.dg/pack9.ad[sb] and do:

gcc/xgcc -Bgcc -S -O2 -gnatp pack9.adb -Igcc/ada/rts -fdump-tree-optimized

The .optimized dump shouldn't contain any call to gnat_rcheck_21.


If you install a change, please mention PR tree-optimization/51775.  TIA.
