Data alignment,

mantu55 · 05-24-2012, 01:02 AM

Hi,

I am getting the following warning for the below piece of code when I have build using GNU on Linux,

code:
#pragma DATA_ALIGN(hal_firmware_1b7, 32)

where "hal_firmware_1b7" is a array variable of type short and trying to make array should start at 32 byte aligned memory address.

warning: ignoring #pragma DATA_ALIGN

Are there any other alternatives on GNU/Linux to clear this warning?

Regards,
Mahantesh

Yes, using __attribute__((aligned (32)) when defining the variable (or a type). See Type Attributes in the GCC documentation for details.

Thank you very much...

My warnings are cleared by the following changes,

UInt16 hal_firmware_1b7[] __attribute__ ((aligned(32)));
