[U-Boot] Turning optimizations off

[Fahd Abidi]

Hello,
 
I am debugging u-boot with a BDI and am running into a case where a
variable gets optimized out. For the sake of debugging I am trying to
turn off optimizations.
I have the following in u-boot-2009.01/config.mk, but GDB still reports
optimizations:

OPTFLAGS= -Os -fno-schedule-insns -fno-schedule-insns2
#-fomit-frame-pointer

(gdb) stepi

0x0ff78750 in get_table_entry_name (table=<value optimized out>,

msg=0xff9e1a8 "Unknown Architecture", id=7) at image.c:544

544 }

Does anyone know how to completely turn optimization off? Using no -O
flag results in u-boot not compiling.
