Hi Brian,
Hi every one. I need help with debugging u-boot. If I comple u-Boot without -Os optimization, I get bunch of errors about missing functions. They are inline functions (in_be32, out_be32, out_8, etc) and I'm not sure how to make sure they are included when building the code without optimization.
I'm using ELDK4.1 for windows and u-Boot-1.3.3
Any help or pointers will be appreciated.
You have seen by now, that you cannot disable all optimization to successfully build U-Boot (Linux is the same btw.). I still do wonder, why you want to disable optimization for debugging. Is it because GCC reorders some statements, so gdb seems to jump around in the source lines?
If so, you can suppress the reordering as documented in our DULG[1]:
Add "-fno-schedule-insns -fno-schedule-insns2" to the CFLAGS for U-Boot.
Cheers Detlev
