	3.4.0 20040303 generates ICE. But
	3.4.0 20040227 work fine.

Environment:
System: Linux namsh 2.6.4-rc2 #63 Thu Mar 4 21:18:27 KST 2004 i686 athlon i386 GNU/Linux
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: m6811-unknown-none
configured with: ../configure --disable-nls --target=m6811-elf --prefix=/usr/GNUHCS --program-prefix=m6811-elf- --with-gnu-ld --with-gnu-as --disable-shared --enable-languages=c,c++ --without-headers --with-newlib

How-To-Repeat:
Just do 'm6811-elf-g++ -o tmp.o -c t.cpp -m68hc12'.

The t.ii is:
    # 1 "t.cpp"
    # 1 "<built-in>"
    # 1 "<command line>"
    # 1 "t.cpp"
    class CKMCLink {
    public:
	void LinkDelete(CKMCLink**);
    private:
	CKMCLink *m_prev;
    };

    void
    CKMCLink::LinkDelete(CKMCLink **head)
    {
     if (m_prev == this)
     {
	 *head = 0;
     }
    }
------- Additional Comments From namsh at kldp dot org  2004-03-06 05:26 -------
Fix:
    If I do 'm6811-elf-g++ -o tmp.o -c t.cpp -m68hc11'. No ICE.
    If I use m6811-elf-g++ 3.4.0 20040227 with -m68hc12, No ICE.

m6811-elf can never be considered critical.

Andrew didn't say that, but this must indeed be a target specific thing. It doesn't ICE 
on a compiler targeted for an  x86 linux box.

I test this with new m6811-elf-gcc 3.4.0 20040318.
And ICE occured. I didn't add ICE message for gcc 20040303.
Here it is generated by gcc 20040318.

$ m6811-elf-g++ -o tmp.o -c t.cpp -m68hc12
t.cpp: In member function `void CKMCLink::LinkDelete(CKMCLink**)':
t.cpp:15: internal compiler error: in change_address_1, at emit-rtl.c:1886
Please submit a full bug report,
with preprocessed source if appropriate.

        * config/m68hc11/m68hc11.md ("*lshrsi3_const"): Disable for 68HC12.
        ("*lshrsi3"): Also accept an immediate for 68HC12.

        ("*ashlsi3_const"): Likewise.
        ("*ashlsi3"): Likewise.
        ("cmphi_1_hc12"): Compare two hard register by pushing them and
        comparing with a pop; don't use a split for that.
        ("cmphi split"): Disable compare split for 68HC12.

        * config/m68hc11/m68hc11.c (m68hc11_notice_update_cc): Invalidate
        the status operands if they have side effects.

------- Additional Comments From ciceron at gcc dot gnu dot org  2004-06-06 14:01 -------
The bug was caused by a (MEM:HI (MEM:HI reg)) operand that must be split in two
part to access the low and high byte.  Such split is not possible as there is
no (MEM:HI (PLUS:HI (MEM:HI reg) (const_int 1))).  Fixed (see patches).
