Table 8 − 1. Summary of Options and Their Effects
(a) Options that control the compiler shell
Option Effect
− g Enables symbolic debugging
− r register Reserves global register
− v xx Specifies target processor TMS320C xx (25, 50, 2xx)
(b) Options that control the parser
Option Effect
− pk Makes code K&R compatible
− pw Suppresses warning messages
− p? Enables trigraph expansion
(c) Options that control the optimizer
Option Effect
− o0 Compiles with optimization; register optimization
− o1 Compiles with optimization; + local optimization
− o2 (or − o) Compiles with optimization; + global optimization
− o3 Compiles with optimization; + file optimization
Note that dspmk automatically sets
− oI0 and − op0.
− oe Assumes no calls by interrupts
− ox (equivalent to − x2) Defines _ above + invoke optimizer (at − o2
if not specified differently)
(d) Options that control definition-controlled inline function expansion
Option Effect
− x1 Enables intrinsic function inlining
− x2 (or − x) Defines _ above + invoke optimizer (at − o2
if not specified differently)
