The original Generic_GCC driver can be built on Cygwin, but does not work on non trivial cases. Even Cygwin's old outdated llvm patches use a driver modified from MinGW driver . https://cygwin.com/git-cygwin-packages/ https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/clang.git;a=summary git://cygwin.com/git/cygwin-packages/clang.git https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/llvm.git;a=summary git://cygwin.com/git/cygwin-packages/llvm.git Combining Cygwin and MinGW driver is simple. But the combined code may be ugly. https://github.com/llvm/llvm-project/pull/74933 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
