Description Volker Reichelt 2006-07-05 12:56:19 UTC 
The following invalid code snippet triggers an ICE since GCC 3.1:

============================================================
void foo(long double d)
{
  asm("" :: "a" (d));
}
============================================================

bug.c: In function 'foo':
bug.c:3: error: impossible register constraint in 'asm'
bug.c:4: internal compiler error: in ix86_secondary_memory_needed, at config/i386/i386.c:16554
Please submit a full bug report, [etc.]
