9 years agoMove fold_trunc_transparent_mathfn to match.pd
Richard Sandiford [Fri, 23 Oct 2015 10:01:47 +0000 (10:01 +0000)]
Move fold_trunc_transparent_mathfn to match.pd

This moves the fold rules for trunc, floor, ceil, round, nearbyint and
rint in one go, since they're tested as a group.  Most of the code is
supporting the f(x)->x fold when x is known to be integer-valued.
Like with the non-negative test, this is probably more elegantly handled
by tracking range information for reals, but until that happens, I think
we should handle it analogously to tree_expr_nonnegative_p.

I've incorporated the fix for PR68031 in the new version of
integer_valued_real_p.  However, it seemed confusing to test for an
SSA name at the head of the function rather than the case statement,
and not fall through to tree_simple_nonnegative_warnv_p (which
conceptually shouldn't care whether an update is in progress).
But tree_simple_nonnegative_warnv_p is a no-op for SSA names,
so I simply changed it to:

          return (!name_registered_for_update_p (t)
      && depth < PARAM_VALUE (PARAM_MAX_SSA_NAME_QUERY_DEPTH)
      && gimple_stmt_nonnegative_warnv_p (SSA_NAME_DEF_STMT (t),
  strict_overflow_p, depth));

and used that in the new code too.

Doing these folds later meant that IPA would start to use information
about the aborting sinf and floor in 20030125-1.c before the folds
kicked in.  I changed them from noinline to weak to stop that.
