gnatcheck(1) The GNAT rule checking tool


gnatcheck [OPTION]... filename [-cargs gcc_switches] [-rules rule_switches]

gnatcheck [OPTION]... -files=filename [-cargs gcc_switches] [-rules rule_switches]


gnatcheck checks the conformance of Ada source text with rules and produces a report file for later analysis as well as on standard output.

In the first form, gnatcheck examines the specified Ada source files (wildcards are allowed).

In the second form, gnatcheck examines the Ada source files listed in the specified file.

gnatcheck is an ASIS application developed on top of the ASIS implementation for GNAT. As such, it reads tree files (*.adt) produced by the compiler to accomplish its goals, and invokes gnatgcc for this.


Process RTL units.
-cargs gcc_switches
Pass gcc_switches to GCC when producing the tree files.
Debug mode.
Progress indicator mode, for use in the GNAT Programming Studio.
Print the list of built-in rules.
Full source location chains in report file.
Quiet mode: do not report detections on standard output.
-rules rule_switches

Read rule options from file
