Remove more nonstandard stuff from cosmopolitan.h Fixes #61 2021-03-01 07:42:35 +00:00			`#include "libc/macros.internal.h"`

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. 2021-02-08 17:19:00 +00:00			`// Stores XMM registers to buffer.`

			`// @note modern cpus have out-of-order execution engines`
Expose public garbage collector API for C language You can now do epic things like this: puts(_gc(xasprintf("%d", 123))); The _gc() API is shorthand for _defer() which works like Go's keyword: const char *s = xasprintf("%d", 123); _defer(free, s); puts(s); Be sure to always use -fno-omit-frame-pointer which makes code fast too. Enjoy! See also #114 2021-03-08 18:56:09 +00:00			`_savexmm:`
