Hi,
compiling command is:
opencc -Wunused -IPA:cprop=off -IPA:dce=off -WOPT:ivar_pre=off
-WOPT:icopy=off:copy=off -Wb,-tt32:0x00000400 -O0 --vv hello.c
The input is:
#include<stdio.h>
#define N 100
int main()
{
int i, j, k;
i = 0;
k = 0;
int a[N];
for( j = 0; j < N; j++)
a[j] = j + 4;
return 0;
}
The output is:(there were no i and k)
#include "hello.w2c.h"
extern _INT32 main()
{
_INT32 j;
_INT32 a[100LL];
j = 0;
while(j <= 99)
{
_514 :;
(a)[j] = j + 4;
j = j + 1;
_258 :;
}
goto _770;
_770 :;
return 0;
} /* main */

In the MIPSpro compilers they would be removed in the frontend.
You might want to check where it gets removed starting from the frontend.

Do you mean the compiler does not reserve space on the stack? The place to
look at is the data layout component in CG. Should be simple to keep them with
simple change.

Hi, all
a example(main.c) as follow:
int main()
{
int sum;
int i, j, k;
for( i = 0; i < 100; i++ )
sum = i + 9;
return 0;
}
when I compile it: opencc -CLIST:: main.c
In the file main.w2c.c, there are no j and k, but I need them.Does someone
know how to do?
Thanks!
Eric
