As part of the 7.7 release, IDA bundles a new C++ parser based on the libclang library from the LLVM project.
In addition to that, we wrote a new command-line utility, which allows you to build custom type libraries from C/C++ codebases. (Note: this link is protected by the download area password, included in your latest download e-mail)
Given how powerful those new features are (both the bundled IDA plugin, and the command-line utility), we also created a brand new tutorial, demonstrating how they can be used – from basic usage, to building type libraries for large projects such as the Linux kernel & the iOS SDK.
We hope you find the new tutorial informative!
