GCC has some functions, variables & type attributes which can be used as aliases
for some of the SAL annotations. Although it's not as rich & precise, it's still useful
since we actually enable -Werror on GCC builds whereas we don't use such an option
on MSVC builds.
For now, _Must_inspect_result_ is aliased to warn_result_unused attribute.
config*.cmake files are constantly getting out of sync between
each other. Besides that, the parameters are not really dependent
on a target architecture, but rather on a compiler (except *ARCH)
This approach seems to be more future-prone, and allows to see
all the options in one file (there are really not that many of them)
- Updated toolchain file
- set GCC variable when using CLang in "GCC mode"
- Properly retrieve GCC support libraries
- Various flags needed to get this going
in favor of add_compile_options and the like with generator expressions
Also take this as an opportunity to remove the C++11 standard hack, GCC 8 now defaults to C++14
Instead of messing with global variables and the like, we introduce two target properties:
- WITH_CXX_EXCEPTIONS: if you want to use C++ exceptions
- WITH_CXX_RTTI: if you need RTTI in your module
You can use the newly introduced set_target_cpp_properties function, with WITH_EXCEPTIONS and WITH_RTTI arguments
We also introduce two libraries :
- cpprt: for C++ runtime routines
- cppstl: for the C++ standard template library
NB: On GCC, this requires to create imported libraries with the related built-in libraries:libsupc++, limingwex, libstdc++
Finally, we manage the relevant flags with the ad-hoc generator expressions
So, if you don't need exceptions, nor RTTI, nor use any runtime at all: you simply have nothing else to do than add your C++ file to your module
Since binutils can not add this, we re-introduce pefixup.
It searches for the exported symbol '_load_config_used',
and uses that to fill out the LOAD_CONFIG directory in the PE header
For MSVC, marking the section as discardable will do this automatically.
For GCC, we use a linker script that places it after the .reloc section
(which should be the last "real" section, check ld --verbose output for the
default linker script).
This fixes what seems to be a regression from r55835 (!).
This prevents some errors like this one:
In file included from ../dll/win32/wldap32/ber.c:27:0:
../sdk/include/reactos/wine/debug.h:378:48: error: '__wine_dbch___default' defined but not used [-Werror=unused-const-variable=]

Up to CMake 3.3 LINK_DEPENDS was ignored in non-Makefile generators. See also http://www.cmake.org/pipermail/cmake/2010-May/037206.html. Since CMake 3.4 it is no longer ignored, but requires CMP0005 policy to be set to NEW and it requires a full path which was already correctly used on GCC, but not on MSVC builds.
* [CMAKE] Fix for CMP0018
The new behaviour lets us explicitly disabling position independent code, avoiding the need to change undocumented variables
* LINK_DEPENDS is semicolon separated
* [CMAKE] Fix for CMP0005
it seems impossible to have cmake correct escape PROXY_CLSID_IS so move it to the header
_IMPLICIT_LINK_DIRECTORIES
Othrewise, if you link a RC module with a static C library (as done for
fusion DLLs), you get the standard C libraries from GCC. This is not
what we want.
This might have to be done for MSVC builds. Check build.ninja to verify
this.
