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 run -- hello.c -o hello
$ ./hello
Hello, world!
$
