If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

The Keil Compiler Models

CodeSonar provides the c51 and c251 compiler models for the Keil C51 and C251 C compilers, respectively.

For the Keil MDG-ARM Microcontroller Development Kit C/C++ Compiler, use the armcc compiler model

Overview

Compiler model	Modeled native compiler	Source file extensions (case-insensitive)
c51	Keil C51 C Compiler	C source file: .c C++ source file: .cpp, .cxx
c251	Keil C251 C Compiler	C source file: .c C++ source file: .cpp, .cxx

Compiler model

Modeled native compiler

Source file extensions (case-insensitive)

c51

Availability

Platform Availability

The c51 and c251 compiler models are available for Windows only.

Default Recognition/Handling

By default, compilations are recognized and handled as follows.

Platform	Native Compiler	Model Used
Windows only	c251.exe	c251
Windows only	c51.exe	c51

Specifying Additional Mappings

If your compiler executable has a different name, specify a corresponding COMPILER_MODELS rule to map your executable name to the c51 or c251 model.

Model-Specific ABI Key Format	There is no model-specific ABI key format for the c51 and c251 compiler models.
Compilation Mode	Compilation mode for each source file is determined from the file extension as described above. Source files with other extensions are ignored.
Include paths	Include paths will be: c51_install_path/../INC , where c51_install_path is considered to be the parent of the directory containing the compiler executable, and each dir listed in the value of environment variable C51INC (for c51 model) / C251INC (for c251 model), and each dir specified with compiler directive INCDIR(dir).
Preinclude path	The model will specify --preinclude $CSONAR/csurf/csinclude/cs51_builtins.h unless environment variable CS_NO_C51_BUILTINS is defined. (Where $CSONAR is the CodeSonar installation directory.)
Environment Variables	Environment variables and their values are determined from the system environment (that is, the environment in which CodeSonar is invoked).

each dir listed in the value of environment variable C51INC (for c51 model) / C251INC (for c251 model), and
each dir specified with compiler directive INCDIR(dir).

Preinclude path

The model will specify --preinclude $CSONAR/csurf/csinclude/cs51_builtins.h unless environment variable CS_NO_C51_BUILTINS is defined.
(Where $CSONAR is the CodeSonar installation directory.)

Environment Variables

Environment variables and their values are determined from the system environment (that is, the environment in which CodeSonar is invoked).
