Using the GCC compiler on Linux, the code above must be compiled using the -g flag in order to include appropriate debug information on the binary generated, thus making it possible to inspect it using GDB. Assuming that the file containing the code above is named example.c, the command for the compilation could be: $
stabs was an early format for debugging symbols on Unix-like systems. The newer DWARF format, for which formal specifications exist, has largely supplanted it. The specification allows any compatible compiler or assembler to create debug symbols in a standardized format, and for any debugger, such as the GNU Debugger (GDB), to gain access and display these symbols.
Research compilers are mostly not robust or complete enough to handle real, large applications. They are used mostly for fast prototyping new language features and new optimizations in research areas. Open64: A popular research compiler. Open64 merges the open source changes from the PathScale compiler mentioned.
The free software GNU toolchain (including GNU Compiler Collection (GCC), GNU Debugger (GDB), and GNU make) is available on many platforms, including Windows. [15] The pervasive Unix philosophy of "everything is a text stream" enables developers who favor command-line oriented tools to use editors with support for many of the standard Unix and ...
The GNU Binary Utilities, or binutils, is a collection of programming tools maintained by the GNU Project for working with executable code including assembly, linking and many other development operations.
Time travel debugging or time traveling debugging is the process of stepping back in time through source code to understand what is happening during execution of a computer program. [1]
The Python plugin, which links against libpython, and allows one to invoke arbitrary Python scripts from inside the compiler. The aim is to allow GCC plugins to be written in Python. The MELT plugin provides a high-level Lisp-like language to extend GCC. [71] The support of plugins was once a contentious issue in 2007. [72] C++ transactional memory
Some programming language implementations expose their debugging functions for use by other programs. For example, some FORTRAN dialects have an AT statement, which was originally intended to act as an instruction breakpoint. Python implements a debugger accessible from a Python program. [6]
