Unicorn-Engine MSVC Native Port Notes

These notes are to help myself and others with the upkeep of the msvc native port
|
|
of unicorn-engine.

:: 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
|
|
that builds the same set of sourcecode files multiple times. They are built once for each
|
|
supported CPU type and force "#include" a CPU specific header file to re-"#define"
|
|
function and variable names that would otherwise be the same for each build.
|
|
These multiple builds of the same files are then all linked together to form
|
|
the unicorn library.
|
|
|
|
As an example when building for "x86_64" cpu type the generated header file "x86_64.h"
|
|
is force included and it contains a bunch of defines such as:
|
|
#define phys_mem_clean phys_mem_clean_x86_64
|
|
So you can see that it adds the cpu type on to the end of each name in order
|
|
to keep the names unique over the multiple builds.
|
|
|
|
The way I handle this in MSVC is to build a seperate cpu specific library, containing
|
|
this set of repeatedly used sourcecode files, for each supported cpu type.
|
|
These cpu specific libraries are then linked together to build the unicorn library.
|
|
|
|
For each supported CPU type
|
|
|
|
* Each CPU specific lib has a "forced include" file specified at:
|
|
Configuration Properties -> C/C++ -> Advanced -> Forced Include File
|
|
so for x86-64 this is "the file "x86_64.h" which is a generated file.
|
|
|
|
|
|
:: Other things
|
|
|
|
* 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__.
|
|
|
|
* There is a tcg-target.c for each target that is included into tcg.c.
|
|
This is done using "#include tcg-target.c"
|
|
It is NOT built separately as part of the *.c files for the project.
|
|
|
|
|
|
:: Info from makefiles
|
|
|
|
This info is compiled here together to help with deciding on the build settings to use.
|
|
It may or may not be of use to anyone in the future once this all builds ok :)
