Description j.vanbemmel 2003-01-08 13:06:01 UTC 
Code below will trigger an ICE:
src/test.cpp:22: Internal compiler error in emit_move_insn, at expr.c:2769

struct X {
   short a,b,c,d;
   short e,f,g,h; // without these, I get "impossible register constraint"
};

class I
{
public:
   virtual bool f( X& p1 ) const = 0;
};

class C : public I
{
   virtual bool f( X& p1 ) const;

   static void g( X& p1 ) asm( "g" );
};

bool
C::f( X& p1 ) const
{
   __asm__ __volatile__( "call g" :  : "r"(p1) : "memory" );
   return true;
}

Release:
gcc version 3.2 20020927 (prerelease) under cygwin

Environment:
cygwin under Win2000

How-To-Repeat:
gcc -c test.cpp

 Hello,
 
 I can confirm that this bug is still present and 3.2.3, 3.3 branch and  
 mainline (20030509) all ICE on the testcase.

State-Changed-From-To: open->analyzed
State-Changed-Why: Confirmed with current CVS.
Comment 4 Dara Hazeghi 2003-06-05 04:11:52 UTC 
Reconfirmed with gcc 3.3 branch and mainline (20030604).
Comment 5 Dara Hazeghi 2003-07-11 21:28:09 UTC 
Reconfirmed with current branch and mainline on i686-linux. This problem is not
specific to cygwin, so changing target appropriately.
