<pre>
    Hi, was able to build latest llvm from git on my MAcBookPro 16" M1 (macOS 12.4)
build produced "fat" libraries (x86_64 and arm64)
I wrote the small program
#include "llvm/Support/Host.h"
#include <iostream>

int main() {  
        std::string tripleDefault = llvm::sys::getDefaultTargetTriple();
        std::string tripleProcess = llvm::sys::getProcessTriple();
        std::cout << "default triple: " << tripleDefault << std::endl;
        std::cout << "process triple: " << tripleProcess << std::endl;
        return 0;
}

resulting binary was arm64 only architecture

when I run it I got
default triple: x86_64-apple-darwin21.5.0
process triple: x86_64-apple-darwin21.5.0

I was expecting to see something like
aarch64-apple-darwin21.5.0
or
arm64-apple-darwin21.5.0

anything but not x86_64

am I wrong?

or this is real issue?

thanks in advance

Dimitry Markman
