Table 3.1: List of Functions
The examples for each was built using CGT 6.0.1 with the following options:
-v28 -mt -ml -g --diag_warning=225 --float_support=fpu32
The only exception being the fast sqrt example built with the options
-v28 -mt -ml -g -O2 --diag_warning=225 --optimize_with_debug --float_support=fpu32
Each example has a script SetupDebugEnv.js that can be used with the scripting console in
CCS to setup the watch windows and graphs automatically in the debug session. Please see
CCS4:Scripting Console for more information
