Stefan Gränitz 949d1d9937 [JITLink] Remove some std::move(MemoryBufferRef) below createLinkGraphFromObject() (NFC) 2021-03-02 15:07:34 +01:00
Lang Hames ec6b71df70 [JITLink][ORC] Enable creation / linking of raw jitlink::LinkGraphs.
Separates link graph creation from linking. This allows raw LinkGraphs to be
created and passed to a link. ObjectLinkingLayer is updated to support emission
of raw LinkGraphs in addition to object buffers.

Raw LinkGraphs can be created by in-memory compilers to bypass object encoding /
decoding (though this prevents caching, as LinkGraphs have do not have an
on-disk representation), and by utility code to add programatically generated
data structures to the JIT target process.

Lang Hames 7113a9a654 [JITLink] Fix endianness bug fedd32e2fa.
The ByteSwap_NN functions return their result rather than modifying their
argument in-place, so we need to write the result back to CPUType here.

Lang Hames fedd32e2fa [JITLink] Read MachO Header CPU field only in jitLink_MachO.
It's the only field we need in this function.

Lang Hames 3cc04f6a41 [JITLink] Add an initial implementation of JITLink for MachO/AArch64.
This implementation has support for all relocation types except TLV.

Compact unwind sections are not yet supported, so exceptions/unwinding will not
work.

Lang Hames 88816bdd2f [ORC][JITLink] Name in-memory compiled objects after their source modules.
In-memory compiled object buffer identifiers will now be derived from the
identifiers of their source IR modules. This makes it easier to connect
in-memory objects with their source modules in debugging output.
