Strange loop behavior: two copies of variable?

HarlanRosenthal — Tue, 04 Jul 2006 04:11:07 GMT

I've got some very strange behavior in very simple code. Trying to read a hex number and translate it using successive multiplication, each hex digit seems to be added to an alternate copy of the accumulating variable. The architecture is ARM, so I thought of register bank switching, but the generated code is using registers from 0 to 7. Anyone ever see something like this before?

Have you checked the write_long()-routine? The behaviour could be explained if it only printed every second nibble.

Sten, my first reaction when I read your post was "I've gone over that already . . ."

. . . and fortunately I went back over it again. The typo was a *little* more subtle than that, but not much. Thank you!
