#785 global variable load error

[Josef Pavlik]

hi all,
compiling the following program, the load of the variable stdout is moved outside the loop, so when the function returns, the content of stdout is 1 instead of 0
try to compile it with --model-small

sdcc --version

#include "8051.h"

data unsigned char stdout=0;
void putchar(char x) {}
volatile unsigned char ch;
void main(void)
{
while (1)
{
stdout=1;
printf("x");
stdout=0; // this load is moved before the loop
if (ch=='Z') return;
}
}
-------------------
_main:
;bg.c:8: while (1)
; genAssign
mov _stdout,#0x00

;bg.c:10: stdout=1;
; genAssign
mov _stdout,#0x01
;bg.c:11: printf("x");
