[Qemu-devel] [PATCH v2 0/5] disas: add libvixl to support A64 disassembly

[Peter Maydell]

Hi. This is a rebased and mildly cleaned up version of Claudio's
RFC patchset from last year to add libvixl to QEMU and use it
for A64 disassembly.

NOTE NOTE NOTE
 * we now link with g++, not gcc (even if the target doesn't
   happen to need the A64 disassembler, since it's a bit hard
   to tell whether there's a C++-source .o file in the link)
 * I've tested Linux (including static link of linux-user) and
   MacOS hosts, but not Windows
 * if you have a visceral dislike of the idea of C++ in the
   QEMU binary now would be a good time to say OMG WTF BBQ


Changes v1 -> v2:
 * fixed minor libvixl bugs that meant it didn't build on 32 bit
   hosts or on Windows
 * only import the files we need from libvixl, rather than
   pulling in 10000 lines of code we never even compile
 * merge aarch64-cxx.cc and aarch64.c into one file
 * rename 'aarch64' to 'A64' since the instruction set we're
   disassembling here is named A64, not AArch64
 * tidied the makefiles a little so we only apply the libvixl
   specific flags to those files

Changes RFC -> v1:
 * some support for C++ compilation is already in master, so
   the rules.mak changes are smaller and simpler
 * I've fixed the output to better fit in a qemu debug log trace
 * I simplified the interface between aarch64-cxx.cc and aarch64.c
   a little bit
 * correctly handle the "no C++ compiler, so no A64 disassembler"
   build case
 * added support for using this as a disassembler for A64 targets
   as well as hosts

This patchset sits on top of target-arm.next.
