[llvm-dev] Is OrcJIT compile-on-demand thread safe?

[Siu Kwan Lam via llvm-dev]

Hi all,

I am trying OrcMCJITReplacement but I am seeing failures whenever multiple
threads calls the same function concurrently.  I am suspecting that the
compile-on-demand feature is not thread safe.

Details of my usecase:

A single JIT engine compiles code and sends the jitted function address to
multiple threads.  So, all threads could be enter the lazy function stub
concurrently.
