PC-lint/FlexeLint for C/C++ Features

Platforms:

• PC-lint for C/C++:
• Windows 7 / Vista / XP / NT / 2000 / 98 / 95 / ME
• DOS (built-in DOS extender)
• FlexeLint for C/C++:
• Unix and Unix-like platforms
  (Linux, AIX, HP-UX, Solaris, Tru64 Unix, MAC, etc.)
• OpenVMS
• Embedded Systems
• virtually any platform supporting C

Compatibility:

• supports K&R C, ANSI C, ANSI/ISO C++
• explicit support for Microsoft, GCC and most other major compilers and libraries
• support for most major embedded-system compilers including bit addressing.
• numerous options to support rogue compilers
• scalars sizes can be specified for cross-compiling

Special Checking Facilities:

• value tracking of auto and static (even global) variable, to detect subtle initialization and value misuse problems
• Inter-function Value Tracking -- The powerful inter-statement value tracking crosses function boundaries. Functions called with specific values are later processed, with these values used to initialize parameters.
• Multi-Pass -- To take full advantage of inter-function tracking and static variable tracking, a multi-pass operation has been introduced.  The user can control the number of passes. (See Designer's Notes)
• with value tracking as an enabling technology, we support ‘semantics’ checking for almost 100 library functions, this checking can be extended to user functions (see function mimicry)
• optional strong type checking (typedef-based) with a rich option set to detect nominal type differences. You can even form a fully checked type hierarchy of scalar types using only typedef
• user-defined semantic checking for function arguments and return values
• find unused macros, typedef's, classes, members, declarations, etc. across the entire project (see weak definials)
• checks flow of control for possibly uninitialized variables.
• explicit support for a subset of the MISRA C and MISRA C++ (TM) (Motor Industry Software Reliability Association) standards
• other special torture tests

Speed:

• Multiple modules are processed at high speed using pre-compiled headers

Message Suppression and Enabling:

• by message number
• by message number and symbol name (including wild cards)
• by message number and symbol type
• by message number and message parameter
• one-line suppression
• by macro name
• for library headers, by message number (a header is library depending on how it is included; this can be overridden via user options)
• for specified functions, by message number
• for expressions

Flexibility:

• indirect files (nested to any depth) can contain filenames, options, environment variables
• format of lint error messages can be customized to support integration with a wide variety of editors and IDEs
• all options can be embedded in user code

Performance:

• fast one-pass operation,  with a multi-pass option for inter-function value tracking
• robust - tables will expand as needed to handle large applications
