Error message unrecognized opcode 'addl' in gcc-4.1.0 powerpc-eabi

[Jeffi Edward.J]

Hi,

I'm using gcc-4.1.0 powerpc-eabi cross compiler.

While compiling an application, the following error messages were issued from the assembler.

/tmp/ccQ2aTtY.s:100:Error: Unrecognized opcode 'addl'
/tmp/ccQ2aTtY.s:110:Error: Unrecognized opcode 'adcl'
....

I checked the PowerPC instruction set manual and I couldn't find out 'addl', 'adcl' instructions.

Does gcc generate wrong assembly code? Is this a bug in 4.1.0? What can be the cause?

br,
Jeff

Those look like x86 instructions.  Are you sure you have a
powerpc-eabi cross-compiler?

Yes. Its powerpc cross tool.
I traced out the problem in the application. These instructions are inline asm from freebsd source with GNU C extension (__GNUC__) conditional compilation flag. I could proceed by undefining the flag for that file. Sorry!

Thanks.

The right way would be to conditionalize the code on an architecture
specific definition like __i386__. IMO you should try to inform the
authors/maintainers of that code to fix it.
