From: "fm3 at os dot inf.tu-dresden.de" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/55940] Incorrect code for accessing parameters with 32-bit Intel hosts Date: Tue, 15 Jan 2013 13:53:00 -0000 [thread overview] Message-ID: <bug-55940-4-WSnO0CG3hP@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-55940-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55940 --- Comment #4 from Frank Mehnert <fm3 at os dot inf.tu-dresden.de> 2013-01-15 13:53:04 UTC --- The problem is that I cannot reproduce this problem either. Some versions of gcc 4.7 might be affected (the affected user uses 'Exherbo gcc-4.7.2-r2'), others not. As far as I can tell, only Intel 32-bit code is affected. Regarding -mrtd: I don't know if this command line parameter is used at all. I've just asked the affected user for the complete command line. But a function with 'cdecl,regparm(0)' should pass all parameters on the stack on 32-bit x86 machines, right? And even if some parameters are passed in registers, EDI is normally not used, only EAX, EDX or ECX but never EDI.
