documentation.
3.3.2 Compiler options starting with –o are deprecated
All compiler options starting with –o are deprecated. These will be replaced by new options
preceded with –q. For example, -opt-report should now be –qopt-report. This is to improve
compatibility with third-party tools that expect –o<text> to always refer to output filenames.
3.3.3 –ansi-alias is enabled by default
To align more closely with gcc, -ansi-alias is enabled by default at –O2 and above. This option
allows the compiler to assume the code follows ANSI aliasing rules when generating code. If
your code does not follow these rules, incorrect code may be generated. To disable this, use –
no-ansi-alias.
3.3.4 Use -I- to control if search path is used for include files with angle brackets
Use of –I- effectively splits the command line include paths specified. Any directories specified
with -I options before -I- are searched only for headers included with the "#include "file""
directive. They are not searched for headers included with angle brackets as in "#include
<file>". If additional directories are specified with -I options after the -I- in the command line,
those directories are searched for all #include directives. In addition, -I- inhibits the use of the
