Compiler crash when using special integers sizes

[Inky-developer]

After reading the first lines of the zig documentation, I found out that zig supports special integers sizes like i7 or i65535. However, the following program:

const std = @import("std");
const print = std.debug.print;

pub fn main() void {
    var strange_int: i129 = 14;
    print("{}\n", .{strange_int});
}

fails with:

>>> zig run hello.zig 
Assertion failed at /home/andy/dev/bootstrap-zig/zig/src/stage1/analyze.cpp:9586 in get_llvm_type. This is a bug in the Zig compiler.
Unable to dump stack trace: debug info stripped

Interestingely, when using an integer type of i185 or higher, the error changes to:

LLVM ERROR: Unsupported library call operation!

integers below i129 seem to work fine for me.

I am using windows with zig version 0.7.0.

with latest compiler:

• compiler no longer asserts
• appears this was fixed after 0.10.0
• it may have been partially fixed at 0.10.0 but missing symbol __umodei4

repro.zig

const std = @import("std");
const print = std.debug.print;

pub fn main() void {
    var num1: i129 = 14;
    print("0x{x}\n", .{num1});

    var num2: i185 = 15;
    print("0x{x}\n", .{num2});

    var num3: i185 = std.math.maxInt(i185);
    print("0x{x}\n", .{num3});

    var num4: i256 = @as(i256, num1) + @as(i256, num2) + @as(i256, num3);
    print("0x{x}\n", .{num4});
}

this was a duplicate of #1485 and fixed with the switch to llvm 15
