[tuples] [PATCH] make gimple-pretty-print.c unary expression print more correctly

[Andrew Pinski]

Hi,
  This patch makes gimple-pretty-print.c more closer to what
tree-pretty-print.c did for unary expressions.  I changed the
conversions; add paren and abs expressions; and fixed up negate
expression.  This fixed a couple of regressions, though it exposed a
new testcase failure (but that is because it was not matching before).

OK?  Bootstrapped and tested on i686-linux-gnu with no regressions.

Thanks,
Andrew Pinski

ChangeLog:

* gimple-pretty-print.c (dump_unary_rhs): Handle conversions correctly.
Handle PAREN_EXPR, ABS_EXPR, and NEGATE_EXPR.
