A commercial software static analysis tool produced by Vector Informatik (originally by Gimpel Software) for the C and C++ languages. PC-lint examines C or C++ programs and finds potential problem areas. PC-lint can look across several modules which allows it to determine issues that a compiler normally does not point out. Options also exist for the detection of MISRA rule violations. This tag is for questions regarding the usage of PC-lint/PC lint Plus.

How to disable evaluation of static_asserts in PC-lint
I am using C++'s static_assert feature to check things at compile time which usually should pass, e.g:
static_assert( SOME_CONSTANT < 1000u, "..." );

#define MACRO_CHECK(a, b, c) \
((a==b) ? b : (SET_VAR, c))
#define SET_VAR \
global_var = 0 \

What am I doing wrong in this lint error suppression attempt? And is there a better way?

And lint (PC-lint via Visual Lint, specifically) gives me a message 1924 on it ("C-style cast -- More Effective C++ #2").
FT_BITS_8 is #defined in a third party header file, and there's…

How does PC-Lint (by Gimpel) look across multiple modules?
I'm using Gimpel's PC-Lint v8.00 on a C codebase and am looking to understand how it traverses modules. The PC-lint manual only goes as far as to say that PC-Lint "looks across multiple modules". How does it do this? For example, does it start with…

Gimpel's PC-lint and Flexelint; Anyone used them?
So I've read a few magazine articles and the website for Gimpel's PC-lint and Flexelint C/C++ compiler.
It's really expensive (at least for me), but it seems like it might have some merit to warrant the cost.
So I'm wondering if anyone else has…
