Compiler strange behavior with variable that use the "const" modifier.

[Claude_Sylvain]

Hello,

I am using CodeWarrior V6.4 on Windows XP professionnal, on a project that use the MCF52223 MCU, and I have noticed a strange behavior of the compiler.

Below the explanation...

When defining an array like the following one:

/* +++ */

const unsigned char my_array[] = {0x01, 0x02, 0x03, 0x04, 0x05};

/* +++ */

This array is put in the .rodata section, and that's just what anybody expect.

But, when defining the save array with all value as 0x00, like the following:

/* +++ */

const unsigned char my_array[] = {0x00, 0x00, 0x00, 0x00, 0x00};

/* +++ */

The array is put in the .bss section !?!?

Why?

Is it a bug, or some strange feature that I do not understand ?

Hello

THere is already another thread around that topic.

You need to use the pragma explicit_zero_data on
