Compiler command for aligning all arrays

helferog — Mon, 15 Jan 2018 07:34:49 GMT

Hey,

I am working with a S32R274 Processor and build the Code with the S32 Studio.

I face the issue, that parameter arrays which are loaded by the SPT must be aligned.

Currently I use global arrays like:

uint32_t fft256_command_list[] __attribute__ ((aligned (8))) = { ... };

and add the alignment manually to each array.

Is there a way to set this alignment by default (as compiler setting) ?

Thanks and best regards

Roger

Hello Roger,

I am afraid, the only possibility is add attribute aligned manually to each array. I tried to search another solution, but it seems gcc does not allow anything else.

Martin
