The resulted a.exe will be free from libgcc_s. Please try.
Using compiler-rt instead of libgcc_s requires extra attention in Cygwin,
because the emulated TLS functionality implemented in compiler-rt can't
share the storage across DLL boundaries.
Thanks for pointing this out.
The comment in the emutls.c explains that.
https://github.com/llvm/llvm-project/blob/main/compiler-rt/lib/builtins/emutls.c#L378-L389
Do you think this is a defect we should accept?
Is there a reason why llvm/clang/compiler-rt can not use Cygwin TLS and must use
Emulated TLS?
Should this discussion be moved to -developers as that level of knowledge seems
to be required?
