Get codebase completely working with LLVM You can now build Cosmopolitan with Clang: make -j8 MODE=llvm o/llvm/examples/hello.com The assembler and linker code is now friendly to LLVM too. So it's not needed to configure Clang to use binutils under the hood. If you love LLVM then you can now use pure LLVM.

Change support vector to Windows 8+ Doing this makes binaries tinier, since we don't need to have all the extra code for supporting a 32-bit address space. It also benefits us because we're able to use WIN32 futexes, which makes locking simpler. b69f3d2488dbaf9dcc541e699f5b7c09fbf046e0 is what officially ended our Windows 7 support. This change is merely a formalization. You can use old versions of Cosmo now and forevermore if you need Windows 7 since our repository is hermetic and vendors all its dependencies. Won't fix #617

Introduce post-linker that converts ELF to PE If you build a static ELF executable in `ld -q` mode (which leaves rela sections inside the binary) then you can run it through the elf2pe.com program afterwards, which will turn it into a PE executable. We have a new trick for defining WIN32 DLL imports in C without any assembly code. This also achieves the optimally tiny and perfect PE binary structure. We need this because it isn't possible to have a GNU ld linker script generate a PE file where the virtual pointer and the file pointer can drift apart. This post-linker can do that. One cool benefit is we can now use a smaller 512-byte alignment in the file, and an even bigger 64kb alignment for the segment virtual addresses, and the executable ends up being smaller. Another program introduced by this change is pecheck.com which can do extensive linting of PE static executables to help explain why Windows won't load it.
