Taking three or more registers as in the test cases from comment #5 and
from Bug 21469, or using regparam, is just asking for trouble on a target
with only six registers available, total. While this is a regression, we
also have cases that didn't compile with old compilers and now do. It is
just a matter of luck if you're going to fix registers -- even the order
in which the statements are expanded to RTL can matter for the register
pressure, and in this case y'all are so unlucky to need a larger number of
registers than what you've left available to the compiler.
I believe this bug should be closed as SUSPEND unless test cases exist
that use neither regparam nor global register variables.
