Do I have to specify The -Wo and -XTb and CA703000: C compiler bug options

Latest Updated:12/01/2011


The -Wo and -XTb options are recommended as a measure for preventing the CA703000: C compiler bug (SBG-T-2264-E: 5.3 1-bit manipulation using &,|, or ^).
Do I have to specify both of these options?


Both options must be specified consecutively, as "-Wo, -XTb". If only one option is specified without specifying the other or if these options are specified in branched locations, the operation cannot be guaranteed.
Be sure to describe both of them in succession as "-Wo, -XTb".
