(GCC is catching up in this area)&lt;p&gt;- Modular design -- if an IDE wants to have syntax highlighting or an Xcode&amp;#x2F;Eclipse&amp;#x2F;IntelliJ like &amp;quot;fix it&amp;quot; feature, they can use the clang frontend to parse the code. Also, GCC&amp;#x27;s &amp;quot;big ball of mud&amp;quot; design (iirc they do some optimizations like constant folding in the parser) makes it harder to hack on unless you&amp;#x27;re already pretty familiar with the codebase.&lt;p&gt;- Less hostile community -- people have tried to clean up GCC but their patches were rejected (see the RMS email link below)&lt;p&gt;- Helps you with standards compliance -- clang will still compile code with compiler-specific extensions but it has an option to output a warning. There are some codebases that have come to rely on these behaviors so clang&amp;#x27;s warnings can help make sure you don&amp;#x27;t end up tied to one specific compiler.&lt;p&gt;- Personally, I like AddressSanitizer (ASan). It does similar checks as Valgrind, but using compile-time instrumentation -- just pass in an additional flag. Gets rid of a dependency.</text><parent_chain><item><author>noobermin</author><text>I&amp;#x27;m not sure if this will stoke a flamewar, because I&amp;#x27;ve never seen a discussion here on this (might just be hanging around different articles).
