RE: Function call problem

["Duszczak, Richard" <richd@enikia.com>]

I would agree with you except that I am looking at a listing generated
directly from the executable.  i.e.:

make ads-test
	compiles test.c to test.o
	Links test.o with crt0.o, libads.a, etc. into ads-test.x (elf file)
	Converts ads-test.x to ads-test.srec
	objdump -d ads-test.x > ads-test.dis

The file ads-test.dis shows that the test() and test2() functions are not
being called.
The same thing shows up when I load it into the dev board.  Wherever test is
called there is a 'bl 100b0' which is the beginning of '.Etext0'.

It seems that the linker does not resolve all function calls.

Anything else you can think of?  I'm going to play around, see if I can
build a plain vanilla program (no library calls, minimal makefile, etc.)

Thanks again for your help,

It looks to me like perhaps you are compiling the new source file, but 
somehow still linking with the old object file that was compiled
before your changes.  This causes the debugger to incorrectly display
stuff, because it is looking at the load map and the new object file,
but memory is from the old object file.  YMMV
