Package: tcc
Version: 0.9.26~git20120612.ad5f375-3
Severity: important
Forwarded:
http://lists.nongnu.org/archive/html/tinycc-devel/2012-06/msg00037.html
The behavior on the following program is incorrect with tcc:
#include <stdio.h>
#define M1 (1 << (int) 1)
#define M2 (1 << (unsigned int) 1)
#define M3 (1 << (long) 1)
#define M4 (1 << (unsigned long) 1)
#define M5 (1 << (long long) 1)
#define M6 (1 << (unsigned long long) 1)
#define OUT(M) \
printf ("%d %s\n", (int) sizeof(M), -M < 0 ? "signed" : "unsigned")
int main (void)
{
OUT(M1);
OUT(M2);
OUT(M3);
OUT(M4);
OUT(M5);
OUT(M6);
return 0;
}
ISO C99 TC3 says: [6.5.7#3] "The integer promotions are performed on
each of the operands. The type of the result is that of the promoted
left operand."
Thus the type of the shift result should be int in the 6 cases.
Correct behavior (with gcc):
4 signed
4 signed
4 signed
4 signed
4 signed
4 signed
Incorrect behavior (with tcc):
4 signed
4 unsigned
8 signed
8 unsigned
8 signed
8 unsigned
