[Bug c++/13781] New: [x86-64] Assembler messages: "operands invalid" for mov in kopete 0.8beta2

I tried to compile kopete 0.8beta2 on an x86-64 CPU running SuSE Professional
9.0, and it failed with the following error:

make[4]: *** [kopetepluginmanager.lo] Error 1

/tmp/cc6r4y77.s looks like:

        movl    $0, 136(%rsp)
        movl    $0, 140(%rsp)
        movl    $0, 144(%rsp)
#APP
        movl %rcx, %eax   **** This is where the error occurs ****
        movl %esi, %edx
        roll $29, %eax ; roll $3, %eax
        rorl $27, %eax ; rorl $5, %eax
        roll $13, %eax ; roll $19, %eax

The default version of gcc is:

Reading specs from /usr/lib64/gcc-lib/x86_64-suse-linux/3.3.1/specs
Configured with: ../configure --enable-threads=posix --prefix=/usr
--with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man

x86_64-suse-linux
Thread model: posix
gcc version 3.3.1 (SuSE Linux)

I have also attempted to compile it from the gcc-3_4-branch and
hammer-3_3-branch, and in both cases the make process stopped in the same place.

Incidentally, it will compile if the -m32 flag is set - it appears to be a code
generation problem only with the x86-64.

Not a gcc bug, the inline-asm is wrong.

There doesn't appear to be any inline assembly code in kopetepluginmanager.cpp,
its pure C++.  Am I missing something?

but it might something in a header, can you attach the __preprocessed__ source file?

This inline-asm is wrong:
asm volatile("movl %1, %%eax\n\t" "movl %2, %%edx\n\t" "roll $29, %%eax ; roll $3, %%eax\n\t" "rorl 
$27, %%eax ; rorl $5, %%eax\n\t" "roll $13, %%eax ; roll $19, %%eax\n\t" "movl %%edx, %0\t" : "=r" 
(_qzz_res) : "r" (&_zzq_args[0]), "r" (0) : "eax", "edx", "cc", "memory" );

%1 can be (and is for x86_64 because pointers are 64bit) one of the 64bit registers.
