This was added as an architecture to LLVM's target triple parser and the Clang driver in 2015. No backend ever materialized as far as I can see (same for GCC). In 2016, other code referring to it started using "Myriad" instead. Ultimately, all code related to it that isn't in the target triple parser was removed. It seems to be a real product, just... literally no one seems to know anything about the ISA. I figure after almost a decade with no public ISA documentation to speak of, and no LLVM backend to reference, it's probably safe to assume that we're not going to learn much about this ISA, making it useless for Zig.

Aro
A C compiler with the goal of providing fast compilation and low memory usage with good diagnostics.
Aro is included as an alternative C frontend in the Zig compiler
for translate-c and eventually compiling C files by translating them to Zig first.
Aro is developed in https://github.com/Vexu/arocc and the Zig dependency is
updated from there when needed.
Currently most of standard C is supported up to C23 and as are many of the common extensions from GNU, MSVC, and Clang
Basic code generation is supported for x86-64 linux and can produce a valid hello world:
$ cat hello.c
extern int printf(const char *restrict fmt, ...);
int main(void) {
printf("Hello, world!\n");
return 0;
}
$ zig build && ./zig-out/bin/arocc hello.c -o hello
$ ./hello
Hello, world!
