GCC modification for ARM

[Charles Steaderman]

I am trying to port RTEMS to an ARM7 CPU. Unfortunately, the chip 
manufacturer has a bug in which data corruption can occur when using DMA 
when a SWP instruction is executed. I know that RTEMS uses patched 
compilers and libraries and I was wondering if anyone is familiar enough 
with GCC to direct me where to make a change to replace the SWP 
instruction with LDR and STR instructions.

Thanks,
- Charlie
