Looking in latex.el shows something like
(TeX-add-style-hook "pdftex" 'TeX-PDF-mode-on)
(TeX-add-style-hook "pdftricks" 'TeX-PDF-mode-on)
(TeX-add-style-hook "pst-pdf" 'TeX-PDF-mode-on)
(TeX-add-style-hook "dvips" 'TeX-PDF-mode-off)
;; This is now done in style/pstricks.el because it prevents other
;; pstricks style files from being loaded.
;; (TeX-add-style-hook "pstricks" 'TeX-PDF-mode-off)
(TeX-add-style-hook "psfrag" 'TeX-PDF-mode-off)
(TeX-add-style-hook "dvipdf" 'TeX-PDF-mode-off)
(TeX-add-style-hook "dvipdfm" 'TeX-PDF-mode-off)
;; (TeX-add-style-hook "DVIoutput" 'TeX-PDF-mode-off)
;;
;; Well, DVIoutput indicates that we want to run PDFTeX and expect to
;; get DVI output. Ugh.
(TeX-add-style-hook "ifpdf" (lambda ()
(TeX-PDF-mode-on)
(TeX-PDF-mode-off)))
;; ifpdf indicates that we cater for either. So calling both
;; functions will make sure that the default will get used unless the
;; user overrode it.
