Error : Unrecognizable insn

[Mosfet <forumer@xxxxxxxxxxxxxxx>]

Hi,

We are trying to build a language D cross compiler for arm smartphone
running under Windows Ce. It is based on gcc 4.1.x and we have used a patch
to add the D front end (http://dgcc.sourceforge.net/). It seems that we
successed in building the D cross compiler, but we have troubles with the
phobos library, which is the basic library of the D language. Here is the
first error that we got :

/home/baptiste/cegcc/src/gcc/libphobos/std/c/windows/com.d: In member
function 'AddRef':
/home/baptiste/cegcc/src/gcc/libphobos/std/c/windows/com.d:225: error:

                (call (mem:SI (reg/f:SI 105) [0 S4 A32])
                    (const_int 0 [0x0])))
            (return)
            (use (const_int 0 [0x0]))
        ]) -1 (nil)
    (nil)
    (expr_list:REG_DEP_TRUE (use (reg:SI 0 r0))
        (nil)))
/home/baptiste/cegcc/src/gcc/libphobos/std/c/windows/com.d:225: internal
compiler error: in extract_insn, at recog.c:2084

We have tried to comment the line 225, of course it temporary solved this
problem but we got similar errors at other lines.

Can anybody explains me what means the "unrecognizable insn" error ?

Thanks in advance,

Baptiste
