And I don't understand why he is using two ldrb instructions!
Both compilers were called with "-g -O0" Using -O3 creates smaller code but still uses ldrb.
Passing "-march=armv4" seems to help. Passing "-mcpu=arm920t" instead helps too.
I used Dan's crosstool to build the toolchain. How can I built a tool chain that makes "good code" (TM) for an arm920t _by default_?
Doesn't crosstool have an arm7tdmi example? I'd start there.
