These tools are for use by developers so that they can create more robust applications. Especially of use to those developing multi-threaded applications in C++ with templates. Includes TCMalloc, heap-checker, heap-profiler and cpu-profiler. Recent news:
Customizing Printf - The GNU C Library
12.13 Customizing printf The GNU C Library lets you define your own custom conversion specifiers for printf template strings, to teach printf clever ways to print the important data structures of your program. The way you do this is by registering the conversion with the function register_printf_function ; see Registering New Conversions . One of the arguments you pass to this function is a pointer to a handler function that produces the actual output; see Defining the Output Handler , for information on how to write this function.Top 10 Ways to be Screwed by "C"
To get on this list, a bug has to be able to cause at least half a day of futile head scratching, and has to be aggravated by the poor design of the "C" language. In the interests of equal time, and to see how the world has progressed in the 20-odd years since "C" escaped from its spawning ground, see my Top 10 Ways to be Screwed by the Java programming language , and for more general ways to waste a lot of time due to bad software, try my Adventures in Hell page. A better language would allow fallible programmers to be more productive. Infallible programmers, of the type unix' and "C" designers anticipated, need read no further.

The GNU C Library
Embedded software often runs on processors with limited computation power, thus optimizing the code becomes a necessity. In this article we will explore the following optimization techniques for C and C++ code developed for Real-time and Embedded Systems. Many techniques discussed here have roots in the material we covered in the articles dealing with C to Assembly translation.

Before you begin to use the LLVM system, review the requirements given below. This may save you some trouble by knowing ahead of time what hardware and software you will need. Hardware LLVM is known to work on the following platforms: LLVM has partial support for the following platforms: Note
