Remove RTC switch from configure.cmd, now MSVC runtime checks are
supposed to be enabled/disabled via CMake define (-DRUNTIME_CHECKS=1)
Prepare for adding more dynamic analysis options
- 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.
Some numbers (obtained with my local builds):
Before / After => Reduction
===========================
freeldr.sys : 443 KB ( 453.632 bytes) / 364 KB ( 372.736 bytes) => ~ 18%
win32k.sys : 1877 KB (1.922.048 bytes) / 1562 KB (1.599.488 bytes) => ~ 17%
ntoskrnl.exe : 2253 KB (2.307.072 bytes) / 1902 KB (1.947.136 bytes) => ~ 15.6%
kernel32.dll : 3008 KB (3.080.192 bytes) / 2906 KB (2.975.744 bytes) => ~ 3.4%
This is no official system DLL and WineD3D is its only user. But latest WineD3D prefers the libtxc_dxtn codebase instead of the alternative library we used.
This is also what Mesa uses and Fedora ships now that the patents have expired, so we should stick to the same.
I'm importing the libtxc_dxtn-1.0.1 codebase from https://people.freedesktop.org/~cbrill/libtxc_dxtn/
It compiles warning-free in our tree without modifying a single line!
I'm merging this Pull Request based on the positive response in CORE-12759.
I lack a proper test case myself, but my version at least shouldn't make things worse. In my opinion, the previous one was broken anyway due to using stdcall imports when WineD3D called cdecl ones.
This also removes the NSWPAT option from our buildsystem as dxtn was its latest user.
