The '__' prefix should only be used for the parts of the ORC runtime that
implement compiler / loader runtime details (e.g. ORC-RT's __tlv_get_addr
implementations).
This patch only fixes the public API. Future changes will fix internal names.
This change enables integrating orc::LLJIT with the ORCv2
platforms (MachOPlatform and ELFNixPlatform) and the compiler-rt orc
runtime. Changes include:
- Adding SPS wrapper functions for the orc runtime's dlfcn emulation
functions, allowing initialization and deinitialization to be invoked
by LLJIT.
- Changing the LLJIT code generation default to add UseInitArray so
that .init_array constructors are generated for ELF platforms.
- Integrating the ORCv2 Platforms into lli, and adding a
PlatformSupport implementation to the LLJIT instance used by lli which
implements initialization and deinitialization by calling the new
wrapper functions in the runtime.
