Linking code from multiple separate QAPI schemata into the same
program is possible, but involves some weirdness around built-in
types:
* We generate code for built-in types into .c only with option
--builtins. The user is responsible for generating code for exactly
one QAPI schema per program with --builtins.
* We generate code for built-in types into .h regardless of
--builtins, but guarded by #ifndef QAPI_VISIT_BUILTIN. Because all
copies of this code are exactly the same, including any combination
of these headers works.
Replace this contraption by something more conventional: generate code
for built-in types into their very own files: qapi-builtin-types.c,
qapi-builtin-visit.c, qapi-builtin-types.h, qapi-builtin-visit.h, but
only with --builtins. Obey --output-dir, but ignore --prefix for
them.
Make qapi-types.h include qapi-builtin-types.h. With multiple
schemata you now have multiple qapi-types.[ch], but only one
qapi-builtin-types.[ch]. Same for qapi-visit.[ch] and
qapi-builtin-visit.[ch].
Bonus: if all you need is built-in stuff, you can include a much
smaller header. To be exploited shortly.
Backports commit cdb6610ae4283720037bae2af1f78bd40eb5fe71 from qemu
Whenever qapi-schema.json changes, we run six programs eleven times to
update eleven files. Similar for qga/qapi-schema.json. This is
silly. Replace the six programs by a single program that spits out
all eleven files.
The programs become modules in new Python package qapi, along with the
helper library. This requires moving them to scripts/qapi/. While
moving them, consistently drop executable mode bits.
Backports commit fb0bc835e56b894cbc7236294921e5393c786ad8 from qemu
- in appveyor, install clang and cmake in cygwin, enable package upgrades, and build cmocka and enable testing for gcc only
- in `gitignore`, ignore generated cmocka folder
- in travis, use brew in osx to install cmocka, and enable testing for gcc and clang on os x and linux
- in `Makefile`, change to use `uname -s` to determine os type
- make `install-cmocka-linux.sh`, a simple shell script to download and install cmocka on linux
- in `bindings/Makefile`, enable `make -c` to call subdirectory makefiles instead of `cd [dir] && make` and include environment variables for runtime access to generated libraries
- in `samples/Makefile`, change to use `uname -s` to determine os type, remove `clean_bins` from `all` command, and include `Werror` for compile strictness
- in `tests/unit/Makefile`, add `cflags` for compile time access to cmocka headers and library, include execute vars for runtime access to cmocka and unicorn libs
- in `tests/unit/test_tb_x86.c`, comment out assert that would not compile
While uc_mem_unmap does unmap memory regions from Unicorn, it does not
free the memory. It accumulates over time when reusing a single Unicorn
instance.
This lets you import the pre-built unicorn.dll files with Microsoft
Visual C++ projects.
There is support for static and dynamic linking of dlls. This has been
tested as working for both 32bit and 64bit versions.
The dynamic linking code should also work in Linux, though I have not
tested it.
