Lots of code in the sparc backend dealing with computing
the frame size uses 'int' where HOST_WIDE_INT is more
appropriate.  The attached testcase, when compiled for
any sparc target will show the errors that result,
such as "save" instructions with an immediate operand
being a very large negative number.
Compile above program on Sparc, look at assembler
output or try to run the testcase :-)
Make Sparc backend use HOST_WIDE_INT as appropriate.
