[Bug c++/30637] New: The options -fno-unit-at-a-time and -finline-functions generates erroneous code

[steby at enea dot se]

When compiling the attached source code snippet test.cpp with the options
-fno-unit-at-a-time and -finline-functions, erroneous code is produced in form
of an infinite loop, see the attached disassembly file test.s.

Use the following command line to reproduce the bug:
powerpc-eabi-g++ -c -S -O2 -fno-unit-at-a-time -finline-functions -o test.s
test.cpp

A possible explanation for this bug may be that -fno-unit-at-a-time counteracts
-finline-functions; -finline-functions needs the whole compilation unit or more
while -finline-functions says don't use the whole compilation unit.
