The HP Code Advisor, a source code analysis tool
This release introduces a new tool, HP Code Advisor (cadvise) that enables programmers to detect various
programming errors in C and C++ source code. This tool helps you to identify potential coding errors,
porting issues, and security errors.
You can invoke this tool from /opt/cadvise/bin/cadvise in the command line. For more information
on how to use the various options in this tool, see the HP code Advisor Release Notes.
The updated version of the HP Code Advisor is also available for free download at:

The -fshort-enums Command-Line Option
This new command-line option allocates only as many bytes as required for the declared range of possible
values to an enum type. The enum type is equivalent to the smallest integral type, which has enough memory
space for the declared enumerator range.
NOTE Using -fshort-enums causes the compiler to generate code that may be binary
incompatible with the code generated without this option. To generate compatible code, do
not use or define external enumerators (defined or used in other source files or shared
libraries) that are compiled without this option.
