 Optimization ideas:
-- 64-bit atoms in 64-bit mode ?
+- use 64 bit JSValue in 64 bit mode
+- use JSValue as atoms and use a specific constant pool in functions to
+  reference atoms from the bytecode
 - reuse stack slots for disjoint scopes, if strip
 - add heuristic to avoid some cycles in closures
-- small String (0-2 charcodes) with immediate storage
+- small String (1 codepoint) with immediate storage
 - perform static string concatenation at compile time
-- optimize string concatenation with ropes or miniropes?
 - add implicit numeric strings for Uint32 numbers?
 - optimize `s += a + b`, `s += a.b` and similar simple expressions
 - ensure string canonical representation and optimise comparisons and hashes?
-- remove JSObject.first_weak_ref, use bit+context based hashed array for weak references
 - property access optimization on the global object, functions,
   prototypes and special non extensible objects.
 - create object literals with the correct length by backpatching length argument

+The executables included in this archive run on Linux, Mac, Windows,
+FreeBSD, OpenBSD and NetBSD for both the ARM64 and x86_64
+architectures.
+
+Platform Notes:
+
+- if you get errors on Linux, you should disable the binfmt_misc
+  module which automatically invokes wine with Windows executable:
+
+sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/cli'     # remove Ubuntu's MZ interpreter
+sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/status'  # remove ALL binfmt_misc entries
+
+- Under Windows, you can rename the executables with a .exe extension.
+
+- Use the --assimilate option to build a platform specific binary for
+  better startup time:
+
+  ./qjs --assimilate
+
+- See https://github.com/jart/cosmopolitan for more information about
+  platform specific issues.
