[LLVMdev] [PATCH] New calling convention for use by GHC
Hi all,
As previously mentioned on this list the Haskell compiler GHC has a new
LLVM based back-end. The back-end needs a new calling convention to
efficiently use LLVM and that is what this patch does, just for X86 at
the moment.
Breakdown:
1) Need actual calling convention
Touches:
- include/llvm/CallingConv.h
- lib/Target/X86/X86CallingConv.td
2) Handling new calling

__attribute__((apple_abi)): targeting Apple/ARM64 ABI from Linux (and others)
Hello everyone,
I made a quick patch to clang/llvm to introduce an "apple_abi" function attribute
(https://github.com/aguinet/llvm-project/commit/c4905ded3afb3182435df30e527955031cb0d098),
to be able to compile functions for the Apple ARM64 ABI when targeting other ARM64 OSes
(e.g. Linux). This can be seen as the Apple version of the already existing "ms_abi"
attribute.
