(In reply to comment #10)
It fails on arm-eabi with -mthumb and/or -fPIC.
Currently -fPIC is not well tested.
I have created a separate PR36240 to track all PIC issues.

Please provide a self-contained testcase (see http://gcc.gnu.org/bugs.html )
that ideally abort()s on a wrong result.

While not really useful, i dare to state that SCC(N)-VN unfortunately misses a
lot of what it is ment to serve (IMHO), generally:
1) PR11832

It compiles just fine with the old RA.
If the =r is wrong, then shouldn't it be rejected also with -fno-ira?
