Body
What I want to do (high-level): use qsort_r on Android. There is no default implementation. So I've grabbed one from BSD. Unfortunately it needs fls functions which is also unavailable on Android. So I've grabbed Apple Open Source Libc library and copied ARM implementation into an inline assembly. Now I'm getting this: <pre><code>Assembler messages: Error: selected processor does not support Thumb mode `clz r3,r0' Error: cannot honor width suffix -- `rsb r0,r3,#32' </code></pre> AFAIR ARM-6 doesn't support it in Thumb mode. So how can I force non-Thumb mode for this one file, or is pure C implementation available for fls? (and God, why do I have to play such low-level just to have qsort_r...)

1. COIn your Android.mk file, add ".arm" to the filenames and they will get compiled as ARM mode instead of Thumb mode (e.g. sort.c.arm). I've had mixed Thumb/ARM code in an Android native library and it worked fine.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
