Thanks, I thought you were using -ipa and I thought you were referring to the
IPA summary phase in IPL.
For the lightweight inliner, you are right. In case anyone is interested, if
you
were using the GNU3-based front-end, then you will still see WHILE_DO in
lw_inline.

Gautam:
I just use lw_inline(_LIGHTWEIGHT_INLINER), compiling using
$TOOLROOT/bin/opencc -show -keep -c -INLINE:preempt foo.c
opencc is v4.2.3
thanks
