The new testcase works for me with older releases (-O2 is enough), but 2.95.4
fails as well. The difference from 4.2 to 4.3 is that 4.2 uses two induction
variables, while 4.3 uses one. After lreg 4.2 has

the original code uses -fomit-frame-pointer -fno-gcse -O2. I can verify that
-O3 fixes the issue.

Reproducible even with x86_64-linux - i686-darwin9 cross, at -Os as well as
-O2 -mno-accumulate-outgoing-args. The difference between i686-linux and
i686-darwin9 that matters here is

By disabling asserts, we can compare -O2 call frame for va-arg-25.c test
vs. what would -Os call frame look like:
gcc -O2 -fomit-frame-pointer:
main:
subl$76, %esp
movdqa .LC0, %xmm0

Since 4.x, libssp has had to be disabled for the AVR. Libssp is not required
for building the AVR. I've been meaning to reopen this bug report for a while.
Patch for disabling libssp for the AVR target is

Fixed. For 4.4 we should nuke CHANGE_DYNAMIC_TYPE_EXPR.

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 problem occurs equally with gnu89 extern inline functions as with c99
inline functions (as seen in the initial bug report), so using static inline

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
out what the underlying dataflow problem is and
