Reading specs from ./Linux_3.0/bin/../lib/gcc-lib/i686-pc-linux-gnu/3.0/specs
Configured with: /u/zosma/0/prisme/spion/gcc/gcc/configure --enable-languages=c++ --prefix=/u/zosma/0/prisme/spion/gcc/Linux_CVS
Thread model: single
gcc version 3.0
>Description:
The following function gets compiled into the following
assembly on x86.  GCC 2.95.3 correctly optimized it to
a simple "ret".

_Z1fv:
.LFB1:
        subl    $12, %esp
.LCFI0:
        addl    $12, %esp
.LCFI1:
        ret
>How-To-Repeat:
Compile with "g++ -O2 -S -fomit-frame-pointer" :

void f()
{
  try {}
  catch(...) {}
}
