[arm-gnu] Illegal Instruction

[Stephen Kuo <stephenkuo@xxxxxxxxx>]

Hi Grus


I would like to ask a simple question, it is about "Illegal  
Instruction".
I used the arm-none-linux-gnueabi(2008q1-126) compiler to compile a  
program, the program simply adds 2 float number and output the result.
When I executed the program, I got the "Illegal Instruction".

I have used the same toolchain to build Linux kernel (2.6.25.16) and  
busybox on my ARM9 board (S3C2440),
the kernel and busybox works fine.
(I have enabled the ARM EABI feature in the kernel, which is "Kernel  
Features --> Use the ARM EABI to compile the kernel" in menuconfig)
In addition to add the "-msoft-float" option, do I have to add another  
option to get it run?
S3C2440 does support EABI, right?

By the way, to do more research on this problem, I have used crosstool- 
ng to build a eabi toolchain myself.
Well, all I got is still "Illegal Instruction".
