# MZC8051
code will be changed to this rep:
https://github.com/Jiangshan00001/llvm-mcs51-backend
-------------
https://jiangshan00001.github.io/
a c compiler for mcu8051.
示例程序：
```
void main()
{
int a=4;
}
```
生成对应的ir
```
func:$main;
ret_type: $__main_ret,u0;
{:
def_var: $a,i16;
opr: "init", null;, iconst:0x4:0x10;, %a;
};
func_end:%main;
```
生成对应的8051asm:
```
ORG 0000H; program entry
LJMP __main_before;
__main_before:
MOV 0x81, #0x7f; sp<-#0x7f
NOP;
NOP;
NOP;
LCALL _func___init_global_var;
LJMP _func_main;
_func___init_global_var:
_func___init_global_var_ret_LABEL:
RET;
_func_main:
;def_var: $a,i16;
;addr: 0x8
;opr: "init", null;, iconst:0x4:0x8;, %a;
MOV 0x8, #0x4;
MOV 0x9, #0x0;
_func_main_ret_LABEL:
RET;
```
生成对应的hex:
```
:1000000002000375817F00000012000F0200102221
:0700100075080475090022C8
:00000001FF
```
欢迎任何人参与和完善：一个人可以走的很快，但是一群人却可以走的更远。
