This patch adds support for the `malloc` and `free` functions. These currently aren't implemented in-tree so we first add the interface filies. This patch provides the most basic support for a true `malloc` and `free` by using the RPC interface. This is functional, but in the future we will want to implement a more intelligent system and primarily use the RPC interface more as a `brk()` or `sbrk()` interface only called when absolutely necessary. We will need to design an intelligent allocator in the future. The semantics of these memory allocations will need to be checked. I am somewhat iffy on the details. I've heard that HSA can allocate asynchronously which seems to work with my tests at least. CUDA uses an implicit synchronization scheme so we need to use an explicitly separate stream from the one launching the kernel or the default stream. I will need to test the NVPTX case. I would appreciate if anyone more experienced with the implementation details here could chime in for the HSA and CUDA cases.

The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Getting the Source Code and Building LLVM

Getting in touch
Join the LLVM Discourse forums, Discord chat, or #llvm IRC channel on OFTC.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
