[LLVMdev] How to cache MCJIT compiled object into memory?
Hi, All
I m not sure if this question has been asked or not. I'd like cache the
MCJIT compiled object into memory buffer so it can be reused later. I
followed the Andy Kaylor's example wrote an inherited class from
ObjectCache and use raw_fd_ostream to save the cache and load the cache
from a file. I checked raw_ostream and its subclass, maybe I am wrong but I
don't see one is fit to

[ThinLTO] static library failure with object files with the same name
...he archive made with llvm-ar does not store the full
path). The library contains object files that have been compiled with
`-flto=thin` (compiled with LDC, not clang, but that shouldn't matter).
When linking to that static library, I get the error:
Assertion failed: (ModuleMap.find(ModuleBuffer.getBufferIdentifier()) ==
ModuleMap.end() && "Expect unique Buffer Identifier"), function
generateModuleMap, file ../lib/LTO/ThinLTOCodeGenerator.cpp, line 138.
The error occurs because the buffer identifier uses the filename of the
objects inside the archive, and those are identical for the two fil...

Except that MemoryBuffer is about reading which is "getting". OutputBuffer is about writing, so the "get" part seems wrong. That said, some of the methods could use "const". And there should be an accessor for getting the file path. If wanted to be C++11...

[LLVMdev] [RFC] llvm/include/Support/OutputBuffer.h
For the reasons listed in my 03-May-2012 email, I am proposing a new llvm/Support class for using in writing binary files:
/// OutputBuffer - This interface provides simple way to create an in-memory
/// buffer which when done will be written to a file. During the lifetime of
/// these objects, the content or existence of the specified file is undefined.
/// That is, creating an OutputBuffer
