Implement PowerPC 64-bit native code backend for Linux
Extend the PowerPC 32-bit native code generator for "64-bit PowerPC ELF Application Binary Interface Supplement 1.9" by Ian Lance Taylor and "Power Architecture 64-Bit ELF V2 ABI Specification -- OpenPOWER ABI for Linux Supplement" by IBM. The latter ABI is mainly used on POWER7/7+ and POWER8 Linux systems running in little-endian mode. The code generator supports both static and dynamic linking. PowerPC 64-bit code for ELF ABI 1.9 and 2 is mostly position independent anyway, and thus so is all the code emitted by the code generator. In other words, -fPIC does not make a difference. rts/stg/SMP.h support is implemented. Following the spirit of the introductory comment in PPC/CodeGen.hs, the rest of the code is a straightforward extension of the 32-bit implementation. Limitations: * Code is generated only in the medium code model, which is also gcc's default * Local symbols are not accessed directly, which seems to also be the case for 32-bit * LLVM does not work, but this does not work on 32-bit either * Must use the system runtime linker in GHCi, because the GHC linker for "static" object files (rts/Linker.c) for PPC 64-bit is not implemented. The system runtime (dynamic) linker works. * The handling of the system stack (register 1) is not ELF- compliant so stack traces break. Instead of allocating a new stack frame, spill code should use the "official" spill area in the current stack frame and deallocation code should restore the back chain * DWARF support is missing Fixes #9863 Test Plan: validate (on powerpc, too) Reviewers: simonmar, trofi, erikd, austin Reviewed By: trofi Subscribers: bgamari, arnons1, kgardas, thomie Differential Revision: https://phabricator.haskell.org/D629 GHC Trac Issues: #9863
