please enjoy: my Wasm-hosted, Wasm-targeting build of Clang/Clang++/LLD: a self-contained, 25 MiB (gzipped) pure function

here's how you can use it to "just-in-time" compile and run any C (or C++) code you'd like:

you can also compile executables using printf(), fopen(), etc; indeed in theory you could bootstrap (recompile) LLVM using this very compiler! although CMake makes it fairly annoying to figure out how to run it

this C compiler is really fast! it can compile and link a simple C program in ~65 ms on my machine. (this involves spawning three Wasm "processes")

on the same machine, running the same command with a very similar Clang build natively takes ~80 ms.

this is fast enough for update-as-you-type live coding!

@whitequark Be careful, someone's gonna try to compile the linux kernel with that in hope it's gonna be faster

@whitequark OKAY!! 🥳

@whitequark Catherine I’m worried if you don’t stop we’ll discover it’s webassembly all the way down

@s0 I'm actually more focused on building _up_ than _down_; I did this so that I could compile CXXRTL simulation code and immediately run it in the browser

@whitequark well consider me deeply impressed & respectful as always.

@s0 *bows* thank you!

@whitequark @s0 I look forward to the day I can get steam achievements for formally verifying an AXI interconnect.

@whitequark @s0 and now i'm picturing a character designer screen where you get to choose AMBA, Avalon, or Wishbone instead of a gender

@azonenberg @whitequark @s0 What about an alternative universe with (widened) ISA/68000/maybe 6502 buses used internally?
Show threadAndrew ZonenbergOct 26

@snowfox @whitequark @s0 I don't think any of those support multiple pipelined transactions so it would be super slow.

Would be interesting to imagine what a pipelined variant would look like though

@s0 move over string theory,

@s0 not bad, actually. Build once, optimise closer to the end user CPU

@mo @s0 @whitequark hopefully the WebAssembly Modules work will make this a more common way of providing interoperable libraries with well-defined interfaces.
