RENESAS TOOL NEWS [September 1, 2003: RSO-SQMlint-030901D]
MISRA C Rule Checker
SQMlint V.1.00 Release 1 Released
|
|---|
We have released the SQMlint V.1.00 Release 1, a MISRA C rule checker, for the M32R and M16C families of Renesas MCUs.
- Descriptions
- 1.1 Outline
- The SQMlint, a MISRA C rule checker, is a tool for checking source programs written in C language under the MISRA C rules (*).
When installed, the SQMlint automatically detects the faulty descriptions in a source program that violate the MISRA C rules
by simply compiling the program with the option for using the SQMlint being selected.
The detected faulty descriptions in the source program can be modified as easily as the compile errors in it.
| Note: |
| * |
The MISRA C is Guidelines for the Use of the C Language in Vehicle Based Software.
They were prepared by a non-profit group MISRA (Motor Industry Software Reliability Association) organized
by Japan's automobile industry for software reliability promotion.
The guidelines lay down 127 rules regarding C-language programs for automotive use. |
- 1.2 Features
-
- Checks can be made on 86 rules out of MISRA C's 127 rules.
- Using appropriate options can make checks at compilation.
- Options can be selected to conduct checks on all 86 supported rules, on the specified rules, and on all 86 rules except the specified ones.
- The results of checks are reported in the following two types of message:
- Message in Complaining Level
Delivered if any of the 86 supported rules is violated.
- Message in Warning Level
Delivered if any of the 86 rules may be violated.
- Checks can be conducted in a half or less of time required to compile a program.
- Supported by Renesas's integrated development environments, High-performance Embedded Workshop and TM: descriptions in a C source file can be displayed by tag-jumping from the output message and then modified (the SQMlint is not provided with the function for modifying C-source files).
- Supported by Renesas-specific C-compiler options: for example, when such a special option that interprets variables of type double
as float is used, the SQMlint checks C-source files that have been affected by the option.
For details of the SQMlint, see its datasheet on the Web site.
