Example 40 Generating a detailed diff report using -approot option

$ cadvise report -pdb new.pdb -basepdb old.pdb -approot old:new -all

Report generated using "HP Code Advisor C.XX.XX [Release Date]" on <Machine Name> at <Time> Report command line: "Report Command Line"

New Pdb:	new.pdb
Base Pdb:	old.pdb
Regressions:	0 Improvements:	1 =>2549(1)

As shown in above examples, warning#2223 is emitted at line 4 and is common in both PDBs. User might want to ignore such duplicate warnings while comparing two different versions of PDBs, and hence the -approot option serves the purpose for effective comparison of different PDBs.

6.16 Report options file

All the options that you want to use to generate the report can be consolidated in a single configuration file using the +opts <file> option. This reduces the clutter on the command line and provides a single place to specify the customized options. Comment lines can also be inserted in the +opts configuration file. This option is used for reading reporting options from the specified <file>. The following example shows the reading of report options from a specific file.
