    • testsuite: annotate c-torture/compile tests with dg-require-stack-size · e9b8025b 
          
This patch annotates tests that make use of a significant a mount of
stack space.  Embedded and other restricted targets may have problems
compiling and running these tests.  Note that the annotations are in
many cases not exact.

    • opt-functions.awk: fix comparison of limit, begin and end · 4bc8aadf 
         
The function integer_range_info makes sure that, if provided, the
initial value fills in the especified range.  However, it is necessary
to convert the values to a numerical context before comparing, to make
sure awk is using arithmetical order and not lexicographical order.

    • RISC-V: Fix bad insn splits with paradoxical subregs. · 36ec3f57 
      Shifting by more than the size of a SUBREG_REG doesn't work, so we either
need to disable splits if an input is paradoxical, or else we need to
generate a clean temporary for intermediate results.

Jakub wrote the first version of this patch, so gets primary credit for it.
