How to dissociate constants from text

[Riadh Elloumi]

Hi all,

We are using GCC 3.3.3 cross compilation to ARM9e target. In our ARM9 
chip, we have TCM (tightly coupled memory) which is divided in 32K 
instrcutions (I-TCM) and 32K data (D-TCM). As this memory has a Harvard 
architecture, we get 1 wait state when loading a data from the 
instruction part (I-TCM), and zero wait state when fetching it from 
D-TCM. But arm-elf-gcc involves some constants in the end of functions 
and this makes the code slower when executed in I-TCM than in cache...

Is there any option in gcc, or a patch to make him separate these 
constants from the functions, and map them in, let's say, a .constants 
section that we can load in D-TCM.

Thank you in advance for your help.

Riadh.
