By default, without this option, alloptimizations are enabled. The options --OPT or --OPT=all also enable all optimizations. Optimizationsmay be disabled by using --OPT=none, or individual optimizers may be controlled, e.g.--OPT=as_all will only enable the assembler optimizer.2.4.36 --OUTPUT=type: Specify Output File TypeThis option allows the type of the output file to be specified. If no --OUTPUT option is specified, theoutput file’s name will be derived from the first source or object file specified on the command line.The available output file format are shown in Table 2.6.2.4.37 --PRE: Produce Preprocessed Source CodeThe --PRE option is used to generate preprocessed C source files with an extension .pre. This maybe useful to ensure that preprocessor macros have expanded to what you think they should. Useof this option can also create C source files which do not require any separate header files. This isuseful when sending files for technical support.17
