Clang-CL does not support #pragma function like CL. The alternative to this approach is to disable all intrinsics for this single source file, but that is not trivial to do, as it can only be done by removing a compiler switch, which we have no CMake support for. Therefore this solution is simpler and as good.
MSBuild, via the VS IDE, uses response files when calling CL or LINK.
We cannot specify a custom response file on the linker command-line,
since specifying response files from within response files is forbidden.
We therefore have to pre-process, at configuration time, the linker
script so as to retrieve the custom linker options to be appended
to the linker command-line.
Running out of pool is likely at least during kmtest:ExPools.
There is a chance of crashing when dereferencing these null pointers -- but
worse, there's also a chance of overwriting the IVT or BDA if a VDM BIOS
call is in progress, which can lead to crashes in non-obvious places later.
Modify the .code16 macro so that the 16-bit code segment can get a
chance to be correctly merged with other (possibly 32-bit) code
segments, without keeping generating multiple .text segments with
different attributes and generating the corresponding LNK4078 warning.
This fixes the warning when compiling NTOSKRNL on MSVC:
"v86.S.obj : warning LNK4078: multiple '.text' sections found with different attributes (C0520040)".
- Always use string pooling when building: this helps reducing the
size of the binaries due to string redundancy coming from the usage
of __FILE__ / __RELFILE__ in the debugging helper macros. Note also
that GCC builds use string pooling by default.
- Use suitable add_compile_flags() command.
- Add some explanative comments for some settings.
