Subject: [Bug fortran/38822] Compile-time simplification of x**(real) / ICE in in gfc_target_encode_expr
Date: Tue, 13 Jan 2009 16:33:00 -0000 [thread overview]
Message-ID: <20090113163343.3101.qmail@sourceware.org> (raw)
In-Reply-To: <bug-38822-13404@http.gcc.gnu.org/bugzilla/>
------- Comment #1 from burnus at gcc dot gnu dot org 2009-01-13 16:33 -------
The problem is the following in arith.c:
if (op == INTRINSIC_POWER && op2->ts.type != BT_INTEGER)
goto runtime;
Thus it is only run-time evaluated. gfc_arith_power deals so far only with
(numeric_type)**(integer). We need to handle (complex)**(complex)
and (real)**(real).
I think Fortran 2003 allows ** in initialization expressions (at least I could
not find anything else) and thus one needs this. See also PR 38823.
