Then it must external program interfering with pacman. Some of them are listed here: https://cygwin.com/faq/faq.html#faq.using.bloda pt., 15 cze 2018 o 00:58 waynehamberg napisał(a): > Done that and it still does...

I suppose this is one of GCC emulatedTLS bugs. You'd probably have to use Clang from CLANG64 subsystem to workaround it. Otherwise the best way to solve it is reporting...

I doubt it has anything to do with Clang itself but is probably related to libc++, less likely compiler-rt or libunwind. We would need some profiling results to know what...

Unfortunately I have no idea about profiling on Windows, on Linux I'd start with `perf` and create flamegraph from it.

I don't get how coverage would help here but you'd probably need also `-rtlib=compiler-rt`.

Symlinks don't work without administrator privileges for most of the users so they cannot be used.

@stevenleeS0ht `ln` by default does copy instead of symlink unless you uncomment `set MSYS=winsymlinks:nativestrict`. Then it will use Windows symlinks (which require an elevation).

Generally response files are the solution for such problems but probably there is no easy way to use it with pkgconf.

Regarding this topic: I have made crude Cygwin targets for LLVM but quickly given up since building Cygwin seems to require huge amount of linker scripts magic (tested with x86_64...

FWIW upcoming Zig version will support LLVM 14 but we are moving to LLVM 15 already... So yeah, we need special version for it.
