Hi Jim,
Thanks very much for your email. Will gcc add the optimization support
in the future (method 1)? For method 2, if abs accept short/char, may
I give the function names as sabs and qabs? Gcc does already have cabs
as complex abs, doesn't it?
Best regards
Maggie

Will gcc add the optimization support in the future (method 1)?
Since GCC is a volunteer project, the answer for any sort of question
like that is if somebody writes it, it'll exist and if they don't, it
won't. There's no good way to predict what projects people will find
interesting.
