|
* llvmjit_types.c
|
|
* List of types needed by JIT emitting code.
|
|
*
|
|
* JIT emitting code often needs to access struct elements, create functions
|
|
* with the correct signature etc. To allow synchronizing these types with a
|
|
* low chance of definitions getting out of sync, this file lists types and
|
|
* functions that directly need to be accessed from LLVM.
|
|
*
|
|
* When LLVM is first used in a backend, a bitcode version of this file will
|
|
* be loaded. The needed types and signatures will be stored into Struct*,
|
|
* Type*, Func* variables.
|
|
*
|
|
* NB: This file will not be linked into the server, it's just converted to
|
|
* bitcode.
