Subject: [Bug target/30336]  New: -mtune=native is wrong when not built with gcc
Date: Sun, 31 Dec 2006 00:15:00 -0000	[thread overview]
Message-ID: <bug-30336-682@http.gcc.gnu.org/bugzilla/> (raw)

When gcc isn't built with gcc, we get

  if (arch)
    {   
      /* FIXME: i386 is wrong for 64bit compiler.  How can we tell if
         we are generating 64bit or 32bit code?  */
      cpu = "i386";
    }   
  else
    cpu = "generic";

It is suggested to use size of (void *):

http://gcc.gnu.org/ml/gcc/2006-12/msg00651.html

However, it only checks the pointer size  of the compiler which  is used to
build
gcc, not the pointer size of the gcc.
