qapi: Generate a nicer struct for flat unions 
The struct generated for a flat union is weird: the members of its
base are at the end, except for the union tag, which is at the
beginning.

Example: qapi-schema-test.json has

{ 'struct': 'UserDefUnionBase',
'data': { 'string': 'str', 'enum1': 'EnumOne' } }

{ 'union': 'UserDefFlatUnion',
'base': 'UserDefUnionBase',
'discriminator': 'enum1',
'data': { 'value1' : 'UserDefA',
'value2' : 'UserDefB',
'value3' : 'UserDefB' } }

We generate:

struct UserDefFlatUnion
{
EnumOne enum1;
union {
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
char *string;
};

Change to put all base members at the beginning, unadulterated. Not
only is this easier to understand, it also permits casting the flat
union to its base, if that should become useful.

We now generate:

struct UserDefFlatUnion
{
/* Members inherited from UserDefUnionBase: */
char *string;
EnumOne enum1;
/* Own members: */
union { /* union tag is @enum1 */
void *data;
UserDefA *value1;
UserDefB *value2;
UserDefB *value3;
};
};

Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framework based on QEMU.

Unicorn offers some unparalleled features:

  • Multi-architecture: ARM, ARM64 (ARMv8), M68K, MIPS, SPARC, and X86 (16, 32, 64-bit)
  • Clean/simple/lightweight/intuitive architecture-neutral API
  • Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal and Haskell.
  • Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
  • High performance via Just-In-Time compilation
  • Support for fine-grained instrumentation at various levels
  • Thread-safety by design
  • Distributed under free software license GPLv2
