I was just checking because alpha hardware is quite antique, it's single-core
so a full compile with bootstrap takes around ~72 hours. I don't know how long
the test suite takes because I've never run it on this machine, but I would
expect it to add a couple additional days to that. If that's fine I'll kick it
off, just want to be clear on what exactly you'd like to see.

I have already checked that it doesn't ICE with a crosscompiler. Regarding the
bootstrap, please note that --enable-bootstrap is the default nowadays, so the
option it is not needed to make a full build ("bootstrap"). Also, "make -j N -k
check-gcc" should be enough to test the compiler, since other parts of the
compiler never exercise -mbuild-constants (N in the command should be
substituted with a number of processors to parallelize the testsuite run).

I can queue this up to test on real hardware. By bootstrap, do you mean with --enable-bootstrap, and by test do you mean a full testsuite run or just checking that it doesn't ICE on the reproducer here?
