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.
:: CPU specific libraries
The gnu/gcc way of building the qemu portion of unicorn-engine involves makefile magic
@ -46,34 +53,22 @@ there is a "config-target.h-timestamp" inside each ???-softmmu dir.
* are the following files required? it looks like they might be used by target specific stuff:
gen_all_header.sh (not called)
header_gen.py (can be called by Makefile in unicorn root, but is it ever called)

qemu/arm.h

:: Other things
* GNU 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.
It is NOT built separately as part of the *.c files built for the project.
might have to make intermediate libs, one or each target
* make intermediate libs for every ???-softmmu.
* each intermediate lib has makefiles:
qemu/x86_64-softmmu/Makefile
qemu/config-host.mak
qemu/x86_64-softmmu/config-target.mak
qemu/x86_64-softmmu/config-devices.mak
qemu/Makefile.objs
:: 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 else once this builds ok :)
