The test gcc.dg/pr35065.c fails on i686-apple-darwin9 with:

Excess errors:

Whoops, sorry. I fixed the warnings in a different copy of the testcase
than the one I committed :-( Committed the right version now. (Yes, it still
tests what it should test, without the var-tracking patch it runs

This is not sufficient.
block_New, nal_get_annexeb, block_ChainGather still don't have prototypes and
thus:
warning: cast to pointer from integer of different size
is reported on each of the casts of these function

Actually the code in var-tracking.c does handle the situation that a reg
contains multiple decls. Or better it tries to. If there weren't an
obvious bug in clobber_variable_part(). With that fixed the looping

The immediate problem is that the solution iterates between two orders.
On my machine (i686) it all happen around basic block 231. The even
iterations (after 128 iterations) the var-track info for bb 231 starts with:

Richi,
I looked at this code once but I really do not know this code at all and really
do not want to learn it. It will take a fair amount of time to try to figure
