    • M
      feat(bazel/windows/xp/sp2/inference): implement inference on windows xp · c68e6695
      由 Megvii Engine Team 提交于 
      (os vesion >= sp2) build with bazel

* bazel build support(define __DEPLOY_ON_XP_SP2__ when deploy on xp sp2):
(dbg)./bazel build //brain/megbrain:load_and_run --cpu='x86_windows_xp'
--compiler='clang_cl' -c dbg --copt "-D__DEPLOY_ON_XP_SP2__=1"

(opt)./bazel build //brain/megbrain:load_and_run --cpu='x86_windows_xp'
--compiler='clang_cl' -c opt --copt "-D__DEPLOY_ON_XP_SP2__=1"

* internal behavior:
will define MGB_HAVE_THREAD=0 when enable __DEPLOY_ON_XP_SP2__

* refer to
https://docs.microsoft.com/en-us/cpp/build/configuring-programs-for-windows-xp?view=msvc-160
xp sp2(x86) do not support vc runtime fully, casused by KERNEL32.dll do not
implement some base apis for c++ std function, for example,
std::mutex/std::thread/std::condition_variable as a workround, we will
disable some MegEngine features on xp sp2 env, for exampe, multi-thread etc!

* about DNN_MUTEX/MGB_MUTEX, if your code will build in inference
code (even CPU backends), please replace std::mutex to DNN_MUTEX/MGB_MUTEX,

* about multi-thread, if you code need multi-thread support, please
enable it when MGB_HAVE_THREAD=1

* about test build env status
1: Visual Studio 2019(MSVC version <= 14.26.28801)---- pass
2: Visual Studio 2019(MSVC version > 14.26.28801) ---- failed
   caused by this 'new' version will put VCR depends on win7
   KERNEL32.DLL, this may be fixed at Visual Studio 2019 later version
   but we do not test at this MR merge point
3: Visual Studio 2017   ---------- pass
4: Visual Studio 2014   ---------- pass
