[cfe-dev] lli: LLVM ERROR: Cannot select: X86ISD::WrapperRIP TargetGlobalTLSAddress:i64
> Unfortunately it doesn't look like lli has support for emulated TLS either,
though that would be pretty simple to add.
As an experiment I've `llvm::createLowerEmuTLSPass` into lli which
added @__emutls_v.x and @__emutls_v.t.
However i didn't have any __emultls_get_address calls in my IR.
Is there a llvm pass or compiler-flag that replaces thread_locals with
appropriate __emultls_get_address calls ?

[cfe-dev] lli: LLVM ERROR: Cannot select: X86ISD::WrapperRIP TargetGlobalTLSAddress:i64
What exactly do the compiler flags`-femulated-tls` and `tls-model` do ?
Why does tls-emulation not solve the problem ?
Looking at the generated IR, it seems not to remove thread_local variable
declarations.
What is the reasoning behind that ?
