From 3b1aa7dba7c006b473855a6b199b15fa3a3d77a0 Mon Sep 17 00:00:00 2001 From: Moritz Angermann Date: Thu, 22 Oct 2020 12:08:34 +0800 Subject: Adds AArch64 Native Code Generator In which we add a new code generator to the Glasgow Haskell Compiler. This codegen supports ELF and Mach-O targets, thus covering Linux, macOS, and BSDs in principle. It was tested only on macOS and Linux. The NCG follows a similar structure as the other native code generators we already have, and should therfore be realtively easy to follow. It supports most of the features required for a proper native code generator, but does not claim to be perfect or fully optimised. There are still opportunities for optimisations.
