Global program analysis

The complete program is analyzed and Coverity Fortran Syntax Analysis will flag unreferenced procedures, unreferenced and undefined common blocks, unreferenced and undefined common-block objects, unreferenced modules, unreferenced and undefined public module variables, unreferenced public module constants and unreferenced public module derived types. If the -anref option and the -rigorous are also in effect the call tree will be traversed to detect unsaved common blocks and modules with unsaved public data which are not specified in the root of referencing program units. See also Analysis of the reference structure, Verification of common blocks and Verification of modules. Default: -nancmpl.

Verify the consistency of the global program. If this option is not in effect, only the individual

program units are analyzed. See Global program analysis. Default: -anprg.

Analyze the reference structure. See also Reference structure (Call tree). Default: -anref.

Global program analysis options are global only and must be specified before the filename of any source or library file.
