He would do so. Then approved minutes. -
Language Subsetting in an Industrial Context: a Comparison of MISRA C 1998 and MISRA C 2004
Language subsetting in an industrial context: a comparison of MISRA C 1998 and MISRA C 2004 Les Hatton CISM, University of Kingston∗ November 20, 2005 Abstract The MISRA C standard [7] first appeared in 1998 with the objective of providing a set of guidelines to restrict features in the ISO C language of known undefined or otherwise dangerous behaviour. The standard was assembled by representatives of a number of companies in the automobile sector in response to the rapidly growing use of C in electronic embedded systems in automobiles. The standard attempts to build on the earlier work of [6], [3] and others. Due to various perceived deficiencies, notably considerable ambiguity in the rule definitions, a revision was planned and eventually appeared in 2004. This paper measures how well the two stan- dards compare on the same population of software and also determines how well the 2004 version achieved its stated goals. Given its increasing influence, the results raise important concerns. Keywords: safer subsets, MISRA C, embedded control systems 1 Overview Pragmatic safer subsetting of languages to remove dependence on poorly defined features is finally becoming a mainstream activity with the recent recommen- dation to form a high-integrity study group under the auspices of the ISO, [8] with the intention of producing sets of rules to restrict features with undefined or otherwise dangerous behaviour in programming languages in common use. It frequently comes as a surprise to developers that significant parts of a pro- gramming language can fall into this category. In practice, all standardised programming languages contain problematic features for a variety of reasons which include the inability of the standardising committee to agree on the be- haviour of a particular feature, the use of unintentionally ambiguous language in the standards document itself, omitting to say anything at all and so on. -

MISRA-C Subset of the C Language for Critical Systems SAFETY-CRITICAL SYSTEMS
MISRA-C Subset of the C language for critical systems SAFETY-CRITICAL SYSTEMS System is safety-critical if people might die due to software bugs Examples Automobile stability / traction control Medical automation Many military applications You develop safety-critical software differently from non-critical software MISRA-C MISRA – Motor Industry Software Reliability Association Their bright idea: Can’t avoid C But can force developers to avoid features of C that are known to be problematic Some language flaws Some legitimate features that happen to be bad for embedded software Most of MISRA-C is just good common sense for any C programmer TERMINOLOGY Execution error: Something illegal done by a program Out-of-bounds array reference Divide by zero Uninitialized variable usage Trapped execution error: Immediately results in exception or program termination Untrapped execution error: Program keeps running But may fail in an unexpected way later on E.g., due to corrupted RAM In C, operations with undefined behavior are not trapped SAFETY A safe language does not allow untrapped execution errors A statically safe language catches all execution errors at compile time Useful languages can’t be completely statically safe Java is dynamically safe C and C++ are very unsafe MISRA C is not safe either However, adherence to MISRA-C can largely be statically checked This eliminates or reduces the likelihood of some kinds of untrapped execution errors MISRA-C RULE 1.2 No reliance shall be placed on undefined or unspecified behavior. Lots of things in C have undefined behavior Divide by zero Out-of-bounds memory access Signed integer overflow Lots of things in C have implementation-defined and unspecified behavior printf (“a”) + printf (“b”); Both of these hard to detect at compile time, in general Implementation-defined behavior is fine in MISRA-C Why? MISRA-C RULE 5.2 Identifiers in an inner scope shall not use the same name as an identifier in an outer scope, and therefore hide that identifier. -
