Ok, that's probably caused by

and should be fixed by adjusting the testcase to scan not the gimple dump
but the ccp1 dump.  Can you try that?

Indeed, have verified this with the cross-compiler and the attached patch
should cure this.

I have applied the patch for testing but hit pr65522 regression. 
Restarted build without ada.
Will take about a day to confirm fix.

This test was also failing for target arm-none-eabi, also fixed by Jakub's
