I work at Red Hat onGCC, the GNU Compiler Collection. For the next major release of GCC,GCC 10, I've been implementing a new-fanalyzeroption: A static analysis pass to identify various problems at compile-time, rather than at runtime. My thinking here is that it's best to catch prob...
同时,这些错误还很难调试,因为它们涉及到程序中的三个不同的地方(分配内存、使用所分配内存以及释放内存),这些地方通常相距甚远,并且经常被指针的使用所掩盖。在这篇由两部分组成的文章中,我们将研究GCC 11的增强功能,这些增强功能有助于检测这些影响动态分配内存的错误。另外,David Malcolm在他的文章static analysis ...
astatic analysis passfor identifying various problems at compile-time, rather than at runtime. The initial implementation was aimed at early adopters, who found a few bugs, including a security vulnerability:CVE-2020-1967. Bernd Edlinger, who discovered the issue, had to wade ...
The name of the function. A number of bytes. One or more qualifiers: static, dynamic, bounded. The qualifier static means that the function manipulates the stack statically: a fixed number of bytes are allocated for the frame on function entry and released on function exit; no stack adjustmen...
Abstract: The abstract syntax tree (AST), as an important intermediate representation, plays an important role in the field of static analysis of code. This paper gives a method to reconstruct and visualize the AST based on the textual content of the AST generated by the GCC compiler. The co...

Clang is designed as anAPIfrom its inception, allowing it to be reused by source analysis tools, refactoring, IDEs (etc) as well as for code generation. GCC is built as a monolithic static compiler, which makes it extremely difficult to use as an API and integrate into other tools. Furthe...
