the patch to prevent loadable module build on cygwin
hi,
it seems that cygwin not support the loadable module. But the cmake build
system are going to build loadable module on cygwin, thats because cmake build
system think cygwin is a kind of unix, and the following statment in
/cmake/modules/AddLLVM.cmake lead a loadable module build in cygwin:
macro(add_llvm_loadable_module name)
if( NOT LLVM_ON_UNIX )
message(STATUS "Loadable modules not supported on this platform.
${name} ignored.")
else()
and the follow patch prevent cmake build loadable module on cygwin
diff --git a/cmake/modules/AddLLVM.cmake b/cmake/modules/AddLLVM.cmake
