Ahmed Bougacha	f77c948d56	[Triple][MachO] Define "arm64e", an AArch64 subarch for Pointer Auth. ... This also teaches MachO writers/readers about the MachO cpu subtype, beyond the minimal subtype reader support present at the moment. This also defines a preprocessor macro to allow users to distinguish __arm64__ from __arm64e__. arm64e defaults to an "apple-a12" CPU, which supports v8.3a, allowing pointer-authentication codegen. It also currently defaults to ios14 and macos11. Differential Revision: https://reviews.llvm.org/D87095	2020-12-03 07:53:59 -08:00

Francis Visoiu Mistrih	7b0a5683fa	[MachO] Add cpu(sub)type tests and improve error handling ... Add checks for triples that don't use mach-o, and unit tests for everything.	2020-02-24 10:44:42 -08:00
Francis Visoiu Mistrih	1874dee566	[macho][NFC] Extract all CPU_(SUB_)TYPE logic to BinaryFormat ... This moves all the logic of converting LLVM Triples to MachO::CPU_(SUB_)TYPE from the specific target (Target)AsmBackend to more convenient functions in lib/BinaryFormat. This also gets rid of the separate two X86AsmBackend classes. The previous attempt was to add it to libObject, but that adds an unnecessary dependency to libObject from all the targets.
