Using ARM's OpenMAX DL with GNU compiler

Note: This was originally posted on 27th October 2010 at http://forums.arm.com

Hello,

I have a project in XCode with the target having an ARM11 processor. I would like a faster FFT, so wanted to check out ARM's OpenMAX DL implementation. When I try building with the source files included, I am getting bad instruction errors in all of the .s files. I have been doing some research and people have suggested that there is a different syntax between the ARM RVCT, used to create these .s files, and GNU compliers, which I am using in XCode. Could this be causing these errors? If so, are there any resources on the differnces between the two compilers?

Thanks!
Jamie

The following might be a good starting point for understanding the GNU assembler syntax:

The following would be a good starting point for understanding the ARM assembler syntax:

I understand there are a few scripts out there that can help translate from ARM to GAS. Search for ads2gas.pl and you should be able to find one, but note they aren't perfect and you will probably need to check and alter the resulting source file.
