+ # Assembler
+ This compiler includes an assembler,see `asmtest.hc` for usage. **Put global variables and functions in reigsters before addressing them,the OS may put them within a range that isnt within range of a 32bit jump**(Most memory operations use 32bit offsets,see `MOFFSxx` in `HCRT/Opcodes.DD` if you really want to.).
+ ```
+ U0 Hi() {
+  asm {
+ 	 MOV RAX, &Hello;
+ 	 CALL RAX;
+  }
+ }
+ ```
+ If you suspect the assembler is acting up,open in gdb and type `disas GetVariable("Func_with_asm_in_it").func.funcptr,+100` for a dissambly. I would love to fix any problems in the assembler. Also,make sure you follow the ABI for your OS when using assembler code. And **DONT JUMP INTO ASM BLOCKS FROM HolyC Code**. All registers are unloaded prior to entering an asm block and before any label that an asm block jumps to.

 # Internals
 This compiler uses a modified myjit which runs under windows(new feature),linux(and breifly tested on FreeBSD). The main part of the Compiler is in compile.c. The compiler uses a value stack for temporary values(if they are on the stack on the same time they interfere). The grammar is in `HolyC.y`. The lexer uses a rope data structure provided by a patched `ext/mropes`.  I plan on making a game with this compiler so I will add to the runtime as needed. If you want to add functions,look at `runtime.c`,but a functional text editor is provided in `HolyEd/EDITOR.HC`.
