Unable to build on x86 macOS using LLVM 17.0.6 about blst

[Colerar]

But I can build blst successfully with LLVM 16.

~/Developer/blst master*
❯ bash build.sh
+ /usr/local/opt/llvm@16/bin/clang -O2 -fno-builtin -fPIC -Wall -Wextra -Werror -D__ADX__ -c ./src/server.c
+ /usr/local/opt/llvm@16/bin/clang -O2 -fno-builtin -fPIC -Wall -Wextra -Werror -D__ADX__ -c ./build/assembly.S
+ llvm-ar rc libblst.a assembly.o server.o

~/Developer/blst master*
❯ clang --version
Homebrew clang version 16.0.6
Target: x86_64-apple-darwin23.4.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm@16/bin

I guess this post is related:

https://users.rust-lang.org/t/compiling-inline-asm-with-1-73-0-error-invalid-cfi-advance-loc-expression/101189

Because Rust 1.73.0 also upgrades LLVM to 17.

Seeing this as well.

The problem turns out to be that newer clang, non-Apple build[!?], gets disoriented by labels with dollars in their names. This sounds like a bug, a new one, because for example clang 10, 14, 15, 16 have no problem compiling assembly.S. In which case wouldn't it be more appropriate to say that it's an llvm problem, not blst? As for non-Apple clang build, the latest Apple build appears to be 15, so one can argue that it's not impossible that the problem surfaces down the path even with Apple-provided toolchain... For reference, it doesn't seem to be something homebrew missed when compiling it, because I can reproduce it even on Linux with --target=darwin-x86_64...

So maybe it's a good idea to report this issue to LLVM?
