--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Small testcase which ICEs all the back to GCC 4.1.2:
void g(float*);
void n()
{
    float f;
    int t;
    asm("":"=3Drmf"(f):"0"(0));
    g(&f);
}

The ICE between 4.4 and 4.7 is:
<source>: In function 'n':
<source>:8:1: internal compiler error: in inline_secondary_memory_needed, at
config/i386/i386.c:31107
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

4.1.2 ICE:
<source>: In function 'n':
<source>:8: internal compiler error: in ix86_secondary_memory_needed, at
config/i386/i386.c:15992
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.


The change of the function was r0-82161.=
