From: "dje at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug ada/23519] Dividing fixed point number by zero returns zero. Date: Wed, 31 Aug 2005 16:19:00 -0000 [thread overview] Message-ID: <20050831161807.11465.qmail@sourceware.org> (raw) In-Reply-To: <20050822201829.23519.listor1.rombobeorn@comhem.se> ------- Additional Comments From dje at gcc dot gnu dot org 2005-08-31 16:18 ------- On PowerPC, one needs to emit arithmetic instructions using the mnemonic with the "o" suffix to test for overflow (including divide by zero). The GCC language and/or front-end would need to inform the backend that this is required. Currently GCC cannot represent that overflow test or divide by zero test is required, e.g., with a different RTL code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23519
