GCC 7 To Have Better Test Coverage, Unit Testing

Red Hat developer David Malcolm has shared the work he's been doing on improving the GCC compiler's internal testing to ensure the GNU Compiler Collection is working as anticipated and is generating correct code.

GCC 7 has many new features while Malcom's focus recently has been improving GCC's own test suite to ensure the quality and correctness of the code being generated.

With GCC 7, developers have extended the C front-end so that fragments of GIMPLE (basically GCC's IR) and RTL (closer to machine code) can be embedded for testing, unit testing support has been added to GCC 7, and other low-level improvements.

Those curious about the latest GCC 7 compiler testing improvements can read this Red Hat blog post for all the details.
