Hello world,
the attached patch puts temporary variables, and the statement they are
being generated for, in their own BLOCK.
This may or may not be useful for data locality, and for telling the
middle end explicitly about the lifetime of the temporary variables. It
is intended as a step towards eliminating redundant calls to
array-valued functions whose bounds are unknown at compile time, such as
the original test case for PR 22572.
No test case, as this should not change anything.
Regression-tested. OK for trunk?
