Hi all,
a long time ago (in feb. 2005 !) I posted a small patch for a tiny speed-up
of gcc. (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19832)
According to the latest comment, gcc could be teached to detect such cases
in order to optimize it away by itself.
I do agree that such cases must not be common and that the corresponding
speed improvement in the generated code should be really small, but anyway I
was wondering if I could go up to the end of the story I started a few years
ago.
So, my point is :
* do you think that adding such a fonctionality is easy ? (i.e. for
someone involded in software development, mostly in C for several years and
who has basic knowledge on gcc internals and compilers theory in general)
* do you think it would be usefull ?
* does someone could give me some ideas on where is the best place to do
such a treatment ?
* does someone would agree to mentor it ?
