test syntax as per binary integer comparisons with the option of a unary indirection operator on either expression. eg. 'test *40000 -eq 12345678' checks location 40000 for the value 12345678. I've only implemented 32 bit word indirection - does anyone think it useful to provide half-word and byte as well - in which case what should the syntax look like?
How about using something similar to what the i2c commands use?
<addr>.4 4 byte addr <addr>.2 2 byte addr <addr>.1 1 byte addr
or maybe
<addr>.l 4 byte addr <addr>.w 2 byte addr <addr>.b 1 byte addr
If .<byte-size> isn't specified, then default to the .4 or .l address size.
Potential examples:
test *40000.4 -eq 12345678 test *40000 -eq 12345678 test *40000.2 -eq 1234 test *40000.1 -eq 12
As it happens, the simple_strtoul() parsing is quite happy with a trailing '.' so either should code up easily enough. Thanks for the input...
Last day before the break tomorrow so we'll see what gets done :-))
