Mesa now has only two build systems

Mesa has only two build systems

For the first time since I started the project to use Meson in Mesa, we now only have two build systems in tree, the fewest we’ve had since we started. Yesterday the SCons build system for Mesa was removed, VMWare felt confident enough in Meson to ship a product using Meson instead (both on Windows and Linux). This commit, removed 3600 lines of code and dropped Mesa down to just Meson and Android.mk build files. For reference autotools was removed in 2019, and accounted for 13,000 lines of code.

The first Meson build definition landed in Mesa in 2017, and the process has been a wild ride for me since then. I’ve written wrappers for LLVM dependency handling; fixed Meson on Solaris/OpenIndiana, Haiku, FreeBSD, OpenBSD, and GNU/Hurd; added and fixed hundreds of bugs in Meson; and generally put a ton of effort into the process.

It’s very exciting to see one of the big promises of using Meson for Mesa pay off, we’re down to only 2 in tree build systems.

This Weekend in Meson++ (December 15th)

 It's been a while since I wrote about Meson++, or even worked on it, but I have made some changes since the last time I posted, and I thought it would be a good idea to write about them. Rewriting How Basic Blocks and Instructions are iterated, twice.  The two biggest changes are tightly coupled, and hard to talk about separately. The rewriting of the Basic Block iteration code and the rewriting of the Global Value Numbering pass (GVN). GVN is a critical piece of an SSA based compiler, it tags every variable read and write with a globally unique number. With this information (and with phi nodes), we can easily simplify the program, and eventually propagate raw values into function calls. Our original block walking code had some issues. Those were correctness, and performance. On the correctness side it had two problems, the first is that it didn't necessarily walk the CFG (Control Flow Graph) such that a blocks predecessors were all visited before it was, despite the fact tha...

Rust in Meson — 0.57 Edition

Rust in Meson 0.57 Most people by now have heard of the meson build system I hope (at least anyone who would bother to read this blog post), and Rust is the cool new language everyone wants to use because it guards against specific kinds of memory bugs and has some neat features. The question of course is how to add rust to your existing project using C, C++ or another language. The answer of course, should be build your project with meson. I’m not going to go into whether using Rust is a good idea, whether it’s going to solve all of your problems, eat your puppy, or any of that. Rust, like everything else we do in programming comes with a set of trade-offs. I’ll say though, for the record, that I like Rust as a programming language form the relatively small amount of it I’ve done. So here’s a run down of what’s coming in the meson 0.57.0 release for Rust. Meson level handling for rust editions. Rust editions, for the uninitiated, are roughly equivalent to standards in C and C++. ...

This Weekend in Meson++ (February 6th)

 Meson++ is 1 year old! It's strange to think that February 9th, 2021, was the first commit to meson++, and a year later, we have a working flex+bison C++ frontend, an optimizing mid level IR, a file based backend IR, and the ability to generate simple ninja programs! It's a strange and proud feeling.  Anyway, I haven't implemented any sweepingly huge features this week, but we have landed support for `declare_dependency`, an important first step toward real dependencies (like those found by pkg-config). I also implemented a simple optimization for finding unreachable code. In this case, we look for the `error` function, and mark any instructions after that as dead, as well as removing any next block. Currently, there are no other non-returning functions implemented, but eventually `subdir_done()` will also need to be handled (though `subdir_done()` may present other problems for me). I also started implementing some neat argument pack based variant argument extractors. The...
