The company I work for has long-stable software implementation based on uCLinux
Coldfire.
Some of our apps are approaching a size limit that I believe is caused by the
use of -msep-data (which I believe is used for XIP support - which we don't
use). Here's a typical link error from this change:
hacl.elf2flt(.text+0x938): In function `hacl_InitTimer':
hacl.c:250: relocation truncated to fit: R_68K_GOT16O
haclid_HaclServer_infoGet_Handler
So I tried to build the entire product with DISABLE_XIP=1. This caused
problems that appear to be an error in disk image creation (there seemed to be
nothing in the mounted root filesystem).
So I then tried to remove the -msep-data for just this one application. In
that case the application appears to crash:

I am using gcc v3.4.0 (we've been using the same toolchain and distribution
source code for some time now).
Are there any general suggestions? It seems if I try to adjust anything in
this regards there are severe negative consequences.
Thanks!
