Unicorn-Engine MSVC Native Port Notes
Zak Escano - January 2017
These notes are to help myself and others with the upkeep of the msvc native port
of unicorn-engine.
:: Build settings
Visual Studio Version: Visual Studio 2012 v11.061219.00 Update 5
Platform Toolset: Visual Studio 2012 - Windows XP (v110_xp)
Character Set: Use Multi-Byte Character Set
Runtime Library Debug: Multi-threaded Debug (/MTd)
Runtime Library Release: Multi-threaded (/MT)
Precompiled Header: Not Using Precompiled Headers
Additional Options: /wd4018 /wd4244 /wd4267
:: Winsock inclusion
One of the hacks done for this was to implement usleep() in windows using a
sockets select() function. This then forces the inclusion of winsock stuff
that would otherwise not be required.
usleep() is only used in the second thread that is executed in order to
timeout code that would otherwise continue to execute. So if this is ever
changed to no longer require the usleep() calls, the winsock related code
can be removed entirely.
:: Changes porting unicorn from GNU/GCC to MSVC.
There were many many many changes to make this also build in MSVC
while still retaining the ability to build in GNU/GCC.
Most were due to either GCC specific things or MSVC lack of decent
standard C support especially in VS2012. Also some were for
posix/platform specific stuff that is not present in windows.
Some of the more common changes were:
* Compatibility for GCC style __attribute__'s.
* Change GCC switch case ranges to specify every case individually, ie:
"case 1 ... 3:" changes to "case 1: case 2: case 3:"
* Change GCC struct member initialisation to the more generic
initialisation of all members in order, ie:
{ .value = 1, .stuff = 2 } to { 1, 2 }
* Remove GCC style macro return values which MSVC does not support, ie:
#define RETURN_ONE(x) ({ some stuff; (void)1; })
* Compatibility for posix headers that are missing in windows, ie:
stdbool.h, stdint.h, sys/time.h, unistd.h
:: CPU specific libraries
The gnu/gcc way of building the qemu portion of unicorn-engine involves makefile magic

* The Qemu code for GNU/GCC seems to rely on __i386__ or __x86_64__ defined if
the host is 32bit or 64bit respectively.
So when building 32bit libs in msvc we define __i386__.
And when building 64bit libs in msvc we define __x86_64__.

It is NOT built separately as part of the *.c files built for the project.
This is done using "#include tcg-target.c"
