I mostly agree with you. But in this case, it is already a hard register (rtl generated in epilogue). If the goal is to fix the bug changing only the powerpc end. I must use some constraint already coded in regrename.c. But, IMHO, I did not see anything appropriated. So I resorted to the solution I posted ... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44618
