This is a misfeature that we inherited from LLVM: * https://reviews.llvm.org/D61259 * https://reviews.llvm.org/D61939 (`aarch64_32` and `arm64_32` are equivalent.) I truly have no idea why this triple passed review in LLVM. It is, to date, the *only* tag in the architecture component that is not, in fact, an architecture. In reality, it is just an ILP32 ABI for AArch64 (*not* AArch32). The triples that use `aarch64_32` look like `aarch64_32-apple-watchos`. Yes, that triple is exactly what you think; it has no ABI component. They really, seriously did this. Since only Apple could come up with silliness like this, it should come as no surprise that no one else uses `aarch64_32`. Later on, a GNU ILP32 ABI for AArch64 was developed, and support was added to LLVM: * https://reviews.llvm.org/D94143 * https://reviews.llvm.org/D104931 Here, sanity seems to have prevailed, and a triple using this ABI looks like `aarch64-linux-gnu_ilp32` as you would expect. As can be seen from the diffs in this commit, there was plenty of confusion throughout the Zig codebase about what exactly `aarch64_32` was. So let's just remove it. In its place, we'll use `aarch64-watchos-ilp32`, `aarch64-linux-gnuilp32`, and so on. We'll then translate these appropriately when talking to LLVM. Hence, this commit adds the `ilp32` ABI tag (we already have `gnuilp32`). |

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!
