Invalid instruction on Raspberry pi 4B

[melonedo]

Zig Version

0.11.0

Steps to Reproduce and Observed Behavior

zig build run this code (extracted from std.http.Client):

const std = @import("std");

pub fn main() void {
    var x = std.crypto.hash.sha2.Sha256.init(.{});
    const msg: []const u8 = "hello" ** 100;
    x.update(msg);
}

Will crash because of illegal instuction sha256h in the feature set crypto is not supported. Note that -Dcpu=cortex_a72-crypto does not make a difference:

Edit: -Dcpu=cortex_a72-sha2 works.

Expected Behavior

The code above should not crash.
