Subject: [Bug target/30936] const attribute in nanf prototype causes gcc not producing correct code.
Date: Mon, 26 Feb 2007 08:21:00 -0000 [thread overview]
Message-ID: <20070226082148.11493.qmail@sourceware.org> (raw)
In-Reply-To: <bug-30936-14151@http.gcc.gnu.org/bugzilla/>
------- Comment #4 from pinskia at gcc dot gnu dot org 2007-02-26 08:21 -------
No, the const attribute does not cause to produce wrong code.
On powerpc-darwin with your testcase, I get:
mflr r0
lis r3,ha16(LC0)
la r3,lo16(LC0)(r3)
stw r0,8(r1)
stwu r1,-64(r1)
bl _nanf
li r3,0
fcmpu cr7,f1,f1
bne- cr7,L5
You can see the floating point compare happens but only one call to nanf.
