Hi, Can a gatekeeper please review the appended patch that fixes the issue described below?
Here are testcases that produce failing result when compiled with opencc.
------------------------------
#include <stdio.h>
char myfunc(char i)
{
return i*2;
}
int main()
{
int i=0x40;
printf("size of char %d\n", sizeof(char));
if(myfunc(i) != (char)(i*2.0))
printf("Failed\n");
else
printf("Passed\n");
return 0;
}
------------------------------
#include <stdio.h>
int main()
{
int i=0x40;
if((char)0x80 != (char)(i*2.0))
printf("Failed\n");
else
printf("Passed\n");
return 0;
}
------------------------------
The following test from the GCC 4.2 regression suite:
.../testsuite/gcc.dg/sync-2.c
Problem/Fix Description:
The problem is that the types of the sub-expressions (operands) of a gspin
GS_NE_EXPR operator are not converted correctly during the translation to
a WHIRL I4I4NE expression. The types of the GS_NE_EXPR operands are both
"char" and the translation produces WHIRL sub-expressions of type "int".
The fix is to check the types of the gspin comparison node's sub-expressions
and add conversions as necessary.
Thanks
Pallavi
