Hi,

I am trying to port some code over to MIPSEL from i386. However, I got the
following error:

Please advise what should be the appropriate opcodes for MIPS.

Thanks.

Are you sure you want to assemble for the mips1 target?

I know these both opcodes are valid MIPS32 opcodes, but don't
know if they exist for the mips1 target.

You might want to look for something like

	http://www.cs.cornell.edu/courses/cs314/2005FA/resources/MIPS_Vol2.pdf

but this one is for MIPS32. If you need mips1 you better search
for a likewise document.

HI Freddy,

Thanks a lot for your help.

my target is a MIPS32. Based on what you advised, it must be a wrong
configuration in Linux header files. I'll check and see what'll happen.

Thanks again.

David

I added compiler flag "-Os -pipe -mips32 -mtune=mips32 -funit-at-a-time" .
however I got the following error:

{standard input}: Assembler messages:
{standard input}:8068: Error: Cannot branch to symbol in another section.
{standard input}:8100: Error: Cannot branch to symbol in another section.
{standard input}:8161: Error: Cannot branch to symbol in another section.
{standard input}:8344: Error: Cannot branch to symbol in another section.
{standard input}:8452: Error: Cannot branch to symbol in another section.
{standard input}:8539: Error: Cannot branch to symbol in another section.
{standard input}:8571: Error: Cannot branch to symbol in another section.

I have no platform specific knowledge. Most of my time are on Intel
environment. It does not mean anythign to me. How can this be rectified?

Thanks.
David

You need to use the exactly same compilation options as used for the
kernel. This will fix the problem you see, plus many others you haven't
seen yet.

I could not figure it out in more than 2 hours. I don't even know what
compliantion options used for kernel. I need more instructions and help.

Thanks.

To elaborate on what Thiemo said, take a look at
    http://www.linux-mips.org/wiki/Modules
In particular, see the fourth sentence of the first paragraph.  I think
this solves your problem.
