Building Zig stage3 w/o LLVM and with -Dno-lib fails: TODO implement genBinOp for xor @Vector(32, u8)

[sskras]

Zig Version

Git commit 0c6cb8d

Steps to Reproduce and Observed Behavior

I followed instructions from PR #17892 on Ubuntu 20.04 and GCC 10.3, then added a missed final command line via hint from IRC channel and a workaround from the PR:

./zig2 build -p stage3 --zig-lib-dir lib
# Workaround:
./zig2 build -p stage3 --zig-lib-dir lib -Dno-lib

But the build process still fails:

$ ./zig2 build -p stage3 --zig-lib-dir lib -Dno-lib
zig build-exe zig Debug native: error: the following command failed with 3 compilation errors:

It says TODO implement genBinOp for xor @Vector(32, u8).

Here is the full log of the the terminal session: https://asciinema.org/a/622022
To reach the end of stage2 you may want to jump right to 20:00 or so . stage3 starts circa 21:25.

Expected Behavior

I expected it to finish the process or at least to tell what's wrong in my setup.

You might want to try with -Doptimize=Debug and/or -Dforce-link-libc (TBH already forgot which one worked for me)

[sskras]

Thanks @BratishkaErik. In my case it didn't help:

-Dno-langref -Dno-autodocs ? With these local bootstrapped zig2 builds stage3 fine for me. Just for clarity, I copied all them from https://github.com/gentoo/gentoo/pull/33868/files#diff-3161cd3b11e8ef662a999ec0a5c0bd1a8d8141430e44a40bffecf0d2fe11bb28R125 so this full combination 100% works

[sskras]

I tried these too (as suggested in the channel), no luck. Now I changed my cmd-line to look like yours. It still fails:

$ ./zig2 build install --prefix "$(pwd)/stage3/" -Dno-lib -Doptimize=Debug -Dforce-link-libc -Dno-autodocs -Dno-langref -Denable-llvm=false

I omitted -Dtarget and -Dcpu because I don't know the values you use.

Then our setups might differ in other ways. @BratishkaErik:

1, what is the last ziglang commit that you have built that way?
2, what CC version do you use for bootstrapping?

Thanks @BratishkaErik.

I checked out the same commit as you:

sskras@server-5aef8ee:~/src/github.com/ziglang/zig$ git rev-parse --short HEAD
8ca4a5240

... and built gcc13 from NetBSD/pkgsrc:

sskras@server-5aef8ee:~/src/github.com/ziglang/zig$ cc -v
Using built-in specs.

Then I made a makefile where I used almost identical command line for zig2 as in your build:

$ cat GNUmakefile
all:
        cc -o bootstrap -std=c99 bootstrap.c
        ./bootstrap build
        # ./zig2 build         -p               stage3           -Dno-lib                           -Dno-autodocs -Dno-langref                     --zig-lib-dir lib
        ./zig2 build install --prefix "/stage3" -Dno-lib -Doptimize=Debug -Dforce-link-libc -Dno-autodocs -Dno-langref -Denable-llvm=false

clean:
        git clean -fd

But result (minus some warnings) is largely the same:

@BratishkaErik, could you please find out the whole output of cc -v used for the Gentoo build ?

Tried comparing outputs of cc -v while breaking down and sorting options from the Configured with: ... line:

Red GCC configuration is failing, green configuration builds Zig.

Any ideas? Could that be due to me missing --enable-targets=all or having --disable-multilib ?

mm, would yoy like to try building zig with -Dtarget=native and -Dcpu=native again?

If I switch back to gcc10, the output is essentialy the same (with some warnings being different or just disappearing).
The ./zig2 cmd line is almost identical:

Maybe it's time for me to start learning and debugging Zig code?
Tried digging through the source code:

... but I have no idea of how to indicate the site (code line) that returns the actual self.fail().
